Reptiles of Venezuela -  an updated and commented checklist (2012)

César Molina

The occurrence of Gymnophthalmus lineatus in Venezuela is established for the first time based on a specimen collected on Las Aves Archipelago. We also document the first records of Phyllodactylus ventralis from Los Frailes Archipelago, Amphisbaena alba from Isla de Margarita, and report the occurrence of Thecadactylus cf. rapicauda on Las Aves Archipelago. Additionally we expand the distribution of the snake Leptophis ahaetulla on Isla de Margarita and report the third specimen known from that island. We also present information on the lepidosis and coloration for all species when pertinent.

Introduced species and dubious or erroneous records are discussed. Taxonomic, nomenclatural and distributional comments are provided when required. Considering species of probable occurrence in the country (known to occur in Colombia, Brazil and Guyana at localities very close to the Venezuelan border) and still undescribed taxa, we estimate that the total number of species in Venezuela could exceed 400. Resumen Se actualiza la lista de reptiles de Venezuela a un total de 370 especies (cuatro de ellas exóticas), pertenecientes a 122 géneros (un exótico), 30 familias y tres órdenes. Se discuten las especies introducidas, los registros dudosos o erróneos y se proporcionan comentarios taxonómicos, nomenclaturales o de distribución en casos necesarios. Después de considerar las especies de probable presencia en el país (registros conocidos cercanos a la frontera con Colombia, Brasil y Guyana) y los taxones aun no descritos, se estima que el número total de especies en Venezuela podría superar las 400 especies. Key words: Diversity, Reptiles, South America, Venezuela. Introduction South America harbours some of the most species-rich regions of the world (e.g. the Amazon Basin and the Andes). Venezuela is located at the northernmost portion of the continent and is considered the ninth most reptile diverse country in the world (Aguilera et al. 2003). Partial lists of Venezuelan reptiles have been published using taxonomy-based (Roze 1966; Donoso-Barros 1968; Lancini 1979; Medem 1983; Pritchard & Trebbau 1984) or distribution-based approaches (Roze 1964b; Staton & Dixon 1977; Rivas & Oliveros 1997; Gorzula & Señaris 1999; Markezich 2002; Mijares-Urrutia & Arends 2000; Molina et al. 2004; Rivas Fuenmayor & Barrio-Amorós 2005), but few studies have focused on complete checklists of the Venezuelan herpetofauna (Péfaur 1992; La Marca 1997; Péfaur & Rivero 2000). Among these, only the publication by Péfaur and Rivero (2000) is considered a comprehensive analysis of all Venezuelan bioregions, but their contribution is currently outdated, especially considering all the new species that have been described over the last 10+ years. Venezuela has a considerable diverse reptile fauna. Knowledge of the country’s reptiles has improved considerably in the last two decades, thanks to research conducted by both Venezuelan and foreign herpetologists. Most recent research has been carried out in the Venezuelan Guayana, the Andean region, and the Coastal Ranges. The number of reptile species currently known from Venezuela increased to 370, which is fewer than in Ecuador (414 REPTILES OF VENEZUELA Zootaxa 3211 © 2012 Magnolia Press · 3 species), Colombia (578 species), and Brazil (721 species), but more than in other neighbouring countries like Guyana (170 species), Suriname (143 species) and French Guiana (162 species) (Hoogmoed 1973; Pritchard & Trebbau 1984; Avila-Pires 1995; Métrailler & Le Gratiet 1996; Starace 1998; Abuys 2003; de Massary 2004; Bérnils 2010; Torres-Carvajal & Salazar-Valenzuela 2011; Uetz 2011). Fair comparison between these countries is difficult due to tremendous differences in countries size and varying intensity of collecting efforts. Checklists are dynamic and should be considered as a still frame in time that has no lasting value, only showing the state of knowledge at a peculiar moment. Reports of new species, synonymisations and elevation of old synonyms to specific status, clarification of prior mistakes and new data about species distributions rapidly change our knowledge of biological diversity in tropical countries. With this paper we present the current state of knowledge of the reptile diversity in Venezuela. Materials and methods All data on species geographic distributions are based on published records and voucher specimens housed in museum collections (except in very rare occasions, see specific comments). With few exceptions we examined specimens from all species recorded in this work. No formal record based only on field observations is provided, except for Hydrops martii because a catalogued photographic voucher exists. In order to provide the most accurate species list possible we consulted the pertinent literature published, mostly until march 2011, including: Albuquerque and McDiarmid 2010; Avila-Pires 2005; Avila-Pires and Hoogmoed 2000;

FIGURE 1. Map of Venezuela showing the delimitation of the bioregions considered in this study, which are: 1. Marine (Marina); 2. Insular; 3. Maracaibo Lake Basin (Depresión del Lago de Maracaibo); 4. Mountain Range of Mérida (Cordillera de Mérida); 5. Mountain Range of Perijá (Sierra de Perijá); 6. Lara-Falcón Hill System (Sistema de Colinas Lara-Falcón); 7. Coastal Area (línea costera; highlighted by a grey line); 8. Central Coastal Range (Cordillera de la costa central); 9. Eastern Coastal Range (Cordillera de la costa oriental); 10. Orinoco Delta (Delta del Orinoco); 11. Llanos; 12. Guayana; 13. Amazonia. Note: the Pantepui (fourteenth bioregion considered in this paper) corresponds to the highlands (>1500 m elevation) of the Guiana Shield in the Amazonia and Guayana bioregions. MARN (2001) divided Venezuela into ten main bioregions based on vegetational and climatic characteristics. We consider the Mountain Range of Perijá (Sierra de Perijá) and the Mountain Range of Mérida (Cordillera de Mérida) as distinct bioregions instead of subdivisions of the Andes as proposed by MARN (2001). We also consider the Central and Eastern Coastal Ranges as separate bioregions instead of a single area named “Coastal range” by MARN (2001), and the Amazonia, Guayana and Pantepui as distinct bioregions instead of grouping them under the single term “Guayana” as proposed by MARN (2001), the latter following Hoogmoed (1979), McDiarmid and Donnelly (2005) and Rodríguez et al. (2010). Significant endemism (in flora and fauna) is in favour of considering REPTILES OF VENEZUELA Zootaxa 3211 © 2012 Magnolia Press · 5 these bioregions as separate entities. We thus recognise the following 14 Venezuelan bioregions: 1) Marine; 2) Insular; 3) Maracaibo Lake Basin; 4) Mountain Range of Perijá; 5) Mountain Range of Mérida; 6) Lara-Falcón Hill System; 7) Coastal Area; 8) Central Coastal Range; 9) Eastern Coastal Range; 10) Orinoco Delta; 11) Llanos; 12) Guayana (< 1500 m); 13) Amazonia; and 14) Pantepui [≥ 1500 m above sea level following McDiarmid and Donnelly (2005), even if we agree that this implies some arbitrariness] (Fig. 1). These bioregions also differ from those proposed by Barrio (1998) for amphibians and by Péfaur and Rivero (2000) for amphibians and reptiles. Each bioregion is characterized by a number of taxonomic entities (i.e. orders, families, genera and species) and endemic species. A cluster analysis with Jaccard's coefficient and centroid clustering method was applied to the presence/absence of reptile species to reveal affinities between biogeographical regions. Introduced and/or translocated species, those of dubious occurrence or erroneously reported, and species requiring taxonomic, nomenclatural or distributional comments are also discussed. Museum acronyms follow Leviton et al. (1985), except for MHNLS (Museo de Historia Natural La Salle, Caracas, Venezuela) and MBLUZ (Museo de Biologia, la Universidad del Zulia, Maracaibo, Venezuela). Results Taxonomic Richness We recorded three orders, 30 families, 122 genera (one exotic), and 370 reptile species (four exotics), in Venezuela (Table 1). Previous publications listed 292 (La Marca 1997) and 299 species (Péfaur & Rivero 2000). Although these taxa do occur in Venezuela, the introduced species (Anolis extremus, Ctenosaura similis, Hemidactylus frenatus and H. mabouia) are not included in our species richness analysis. The order Squamata contains 92.0% of the taxa (337 species), followed by Testudines (6.6%, 24 species) and Crocodylia (1.4%, 5 species). The most diverse families within Squamata are Dipsadidae (31.8%, 107 species), followed by Gymnophthalmidae (15.4%, 52 species), Colubridae (11.0%, 37 species), Sphaerodactylidae (7.4%, 25 species), Polychrotidae (7.1%, 24 species), Teiidae (5.0%, 17 species), Elapidae (3.9%, 13 species) and Viperidae (3.6%, 12 species), whereas the most speciose genera are Atractus (8.9%, 30 species), Anolis (6.8%, 23 species), Gonatodes (5.0%, 17 species), Liophis (4.2%, 14 species), Micrurus (3.6%, 12 species), and Anadia and Thamnodynastes with 3.0 % (10 species each).

However, some bioregions are inadequately surveyed (e.g. Guayana, Lara-Falcón Hill System and Perijá) and future work is needed to assess the accurate reptile diversity at these locations. Based on species composition and shared species, bioregions can be clustered in seven groups (Fig. 2; arranged in descending order according to shared species): Guayana + Amazonia; Llanos + Orinoco Delta; Moun- REPTILES OF VENEZUELA Zootaxa 3211 © 2012 Magnolia Press · 27 tain Ranges of Mérida and Perijá; Maracaibo Lake Basin + Central Coastal Range + Lara-Falcón Hill System; Coastal + Insular areas + Eastern Coastal Range. Pantepui and the Marine bioregion are independent entities. Some species (e.g. Pseudoboa neuwiedii, Tantilla melanocephala and Leptodeira annulata) are common elements of the lowlands of the Maracaibo Lake Basin and the Central Coastal Range. Other species (e.g. Anadia steyeri and Euspondylus acutirostris) are known only from the Central Coastal Range and the Lara-Falcón Hill System, whereas other taxa (e.g. Thamnodynastes paraguanae and Cnemidophorus arenivagus) occur only in the Lara-Falcon Hill System and the Maracaibo Lake Basin. Overlapping distributions are thus not consistent and are affected by many ecological factors. The great Andean Mountain chain splits into two branches in extreme northern Colombia (in a region known as the Pamplona knot), one extending northeast into Venezuela being the origin of the Cordillera de Mérida, while the other extends north being the origin of the Sierra de Perijá, which has more affinities with the Cordillera Oriental de Colombia than with the Cordillera de Mérida. Although they are considered as being the Venezuelan Andes, along with the Tamá massif, these two mountain ranges have both geological and biogeographical differences (Ataroff & Sarmiento 1994). Both regions share several Andean and Middle American species (e.g. Anolis jacare, A. biporcatus, Atractus ventrimaculatus, and Lampropeltis triangulum). FIGURE 2. Cluster analysis, with Jaccard's coefficient and centroid clustering method showing the taxonomic similarities between the bioregions considered. Although Pantepui and Marine cluster together they do not share any similarity, these two bioregions are clearly distinct from all other bioregions. Some aquatic species like Paleosuchus palpebrosus, Eunectes murinus, Chelus fimbriatus, Podocnemis expansa, P. unifilis, Hydrops triangularis and Helicops angulatus are distributed throughout the Llanos and the Orinoco Delta. Many of these taxa are also present throughout the Guiana Shield. Anolis onca, Gonatodes vittatus, Mabuya falconensis, and Mastigodryas pleei are all associated with habitats found along the Venezuelan coast. Such habitats are also common on many islands off the Caribbean coast of Venezuela. Endemic taxa found in the mountains of Península de Paria and Turimiquire are related to species from Trinidad, the Guiana Shield lowlands and the forests of the central portion of the Venezuelan Coastal Range (see Schargel et al. 2005). 28 · Zootaxa 3211 © 2012 Magnolia Press RIVAS ET AL. Species endemism One hundred twenty one (33.0%) reptile species are endemic to Venezuela (Table 2, see also Figs. 3 and 4). One hundred nineteen species of these endemics (98.3%) belong to the order Squamata and two species (1.7%) to Testudines. The family Dipsadidae (42 species) is the richest endemic family, followed by Gymnophthalmidae (31 species), Sphaerodactylidae (12 species) and Polychrotidae (10 species). The richest genera in endemic species are Atractus (22 species), Anolis (10 species), Gonatodes (9 species, see Fig. 3), Anadia (9 species), Liophis (6 species), Thamnodynastes (6 species), and Riama (4 species). Only one reptile genus is endemic to Venezuela, Ardecosaurus, which is monotypic and currently known only from the Yutajé-Corocoro massif in the northwestern tepui area (Amazonas State) (Myers & Donnelly 2001). The bioregion with the highest percentage of known endemic species is Pantepui (67.6%), followed by the Mountain Range of Mérida (28.7%), the Central Coastal Range (23.5%), the Insular region (18.4%), the Lara-Falcón hill system (16.3%), the Eastern Coastal Range (16.0%), Perijá (7.2%), Amazonia (6.9%) and Guayana (6.2%). The six remaining bioregions have 5.0% or less (Table 2). Endangered Species In the third edition of the Red Book of the Venezuelan fauna (Rodríguez & Rojas-Suárez 2008), 22 species (6.0% of total species) were listed as critically endangered (CE), endangered (E) or vulnerable (V). Among them, 10 species belong to the order Testudines, five of which are marine turtles (Caretta caretta [E], Chelonia mydas [E], Dermochelys coriacea [CE], Eretmochelys imbricata [CE], and Lepidochelys olivacea [E]) and five are freshwater turtles (Batrachemys zuliae [V], Peltocephalus dumerilianus [V], Podocnemis expansa [CE], P. unifilis [V] and Rhinoclemmys diademata [V]); ten belong to the order Squamata, eight of which are lizards (Ameiva provitaae [V], Anadia blakei [V], A. pariaensis [V], Anolis euskalerriari [V], A. tetarii [V], Euspondylus monsfumus [V], Lepidoblepharis montecanoensis [CE] and Mabuya croizati [V]), and two are snakes (Atractus matthewi [V] and A. turikensis [V]); and two belong to the order Crocodylia (Crocodylus acutus [E] and C. intermedius [CE]) (see Table 1). With respect to the bioregions harbouring species included in the IUCN Red List, Marine is first with 100% of threatened species, followed by the Eastern Coastal Range (7.4%), the Llanos (5.8%), the Mountain Range of Perijá (4.3%), the Maracaibo Lake Basin (4.4%), and the Orinoco Delta (4.3%), the remaining bioregions have 3% or less of threatened species (Table 2).

Rivero-Blanco to J. Peters (Peters & Donoso-Barros 1970). We had the opportunity to examine some specimens of that taxon (MCZ 110294−95 and MBUCV 1889), all of them collected in the city of Caracas, confirming their identification. An additional male specimen, collected in June 2011 in eastern Caracas, was recently brought to the Parque del Este Zoo in Caracas (Fig. 5). This new record confirms that the species is still present in the country, and one of us (GR) also observed A. extremus on the wall of a nursery near Macaracuay, eastern Caracas. This anole, native to the Lesser Antilles, has also been introduced to Trinidad. Ctenosaura similis.—This iguanid lizard originating from Central America has been introduced during recent decades into North America (Savage 2002; Krysko et al. 2003). The Venezuelan population is the first record of the genus in mainland South America, the species inhabits dry forest in the Coastal Area near Barcelona city (BarrioAmorós & Rivas-Fuenmayor 2008; Flores & Esqueda 2008). Date of introduction is unknown. Hemidactylus mabouia.—This species originates from Africa and has long been established in South America, including Venezuela (Kluge 1969). We here report the first record of H. mabouia from the Mountain Range of Mérida, based on a juvenile specimen (MBLUZ 1033) collected on a steel roof beam in the parking lot of a building in Ejido, Mérida. On 12 December 2010 on the Isla La Orchila, Dependencias Federales, we observed several H. mabouia (two collected, MBLUZ 1049–50) in the installations of the national military base. The geckos were very common on building walls as well as on small trees (mainly under loose bark) surrounding the area. In April 2011 we observed H. mabouia mainly on building walls (two juveniles were found on trees within an open area) on the island of Gran Roque, part of Los Roques Archipelago National Park. This species was not found on Los Roques archipelago nor on the island of La Orchila in 1950 (Roze 1954). We presume that these populations were introduced along with construction materials from mainland Venezuela (probably from La Guaira Bayard, Maiquetia International Airport). These specimens are the first records of H. mabouia on oceanic islands of the Venezuelan Caribbean. The species had been previously recorded from other Venezuelan islands, but only of continental origin (e.g. Isla Margarita). Hemidactylus frenatus.—An Asiatic species, which has only recently been recorded in Venezuela (Rivas Fuenmayor et al. 2005b) and appears to be expanding its range in South America (Jadin et al. 2009). 30 · Zootaxa 3211 © 2012 Magnolia Press RIVAS ET AL. Three Venezuelan turtles have been translocated from their natural habitats in Venezuela to other locations inside the country: Chelonoidis carbonaria.—The species was recorded by Meek (1910, as Testudo tabulata) from Los Testigos, an archipelago composed of 16 islands, located 68 km north of the eastern coast of Venezuela. The islands of Los Testigos have different climatic conditions than other archipelagos of the Venezuelan Caribbean Sea. Rainfall reaches an average of 400 mm per year, which allows a greater vegetation cover (Bisbal 2008). Meek (1910) did not mention the origin of this population, which is of special interest because of the early dates of collection (1908−1909). There are two possible origins for that population: (1) Amerindians carried specimens from the mainland as a food source prior to the arrival of Europeans or (2) turtles were brought by pirates, who frequently released goats and tortoises on different islands for food storage. Chelonoidis carbonaria is well known on many Caribbean islands. The population from Isla Margarita has also apparently been introduced (Roze 1964b). Podocnemis expansa.— That species, native to the Orinoco Delta and the most endangered turtle in Venezuela, has become rare in its natural geographic distribution (Barrio-Amorós & Narbaiza 2008). Podocnemis expansa occurs outside its original range at Lago de Valencia, a large lake in the Central Coastal Range, where it is highly endangered as well. The species was introduced in that area in the middle of the last century by the Ministerio de Agricultura y Cría (Fernández 1968). Podocnemis vogli.—Also native to the Orinoco Delta. A population of P. vogli inhabits an artificial reservoir in “Represa Burro Negro” in the Maracaibo Lake Basin. We cannot confirm when this species was introduced, but it was only recently recorded from that locality (Rojas-Runjaic et al. 2007). An adult P. vogli (EBRG 5133) was recently collected in Parroquia Río Negro, Municipio Perijá, Estado Zulia (09°30’15” N, 72°28’47”W). The specimen was collected in a stream bordered by a small gallery forest in a savannah surrounded by flat areas heavily modified by livestock (pastures). The stream is ca. 2 km from Santa Rosa River and about 1 km from the farm “Ecuador”. Apparently specimens of P. vogli were released in some ponds of the farm, which explains the origin of that population. More turtles, both adults and young specimens, were observed on the banks of two artificial lagoons (called Jagueyes) inside the farm. The impact of this population on the local wildlife needs to be evaluated. Undescribed species To our knowledge, at least 30 new species of Venezuelan Squamata are currently being described by various authors. The lizard genera Anadia, Cnemidophorus, Gonatodes and Phyllodactylus still have several species that remain to be formally described (Rivero-Blanco 1979; McBee et al. 1984; unpubl. data from the authors). These genera are speciose and Venezuela could have more species than any other country in which these genera occur. The Guianan-Amazonian genus Neusticurus needs a taxonomic revision, especially the populations under the names N. rudis and N. racenisi (Barrio-Amorós & Brewer Carías 2008; Myers & Donnelly 2008; pers. obs. from the authors), which could lead to the description of new taxa. The family Polychrotidae and the genus Atractus in Venezuela are being revised by GU and GR, and P. Passos and colleagues, respectively, which will certainly yield some additional new species. Species erroneously reported from Venezuela A number of species have been cited erroneously from Venezuela (e.g. in Peters & Orejas-Miranda 1970; Peters & Donoso-Barros 1970; La Marca 1997; Péfaur 1992; Péfaur & Rivero 2000). These species are listed below in alphabetical order with arguments for excluding them from the reptile fauna of Venezuela. REPTILES OF VENEZUELA Zootaxa 3211 © 2012 Magnolia Press · 31 FIGURE 3.

REPTILES OF VENEZUELA Zootaxa 3211 © 2012 Magnolia Press · 33 Order TESTUDINES Batrachemys nasuta.—The species has been cited from Venezuela, but there is no Venezuelan voucher specimen of this taxon. The Batrachemys nasuta specimens mentioned in Pritchard and Trebbau (1984) were captive animals without proper locality of occurrence. Bour and Pauler (1987) and McCord et al. (2001) do not list this species as part of the Venezuelan turtle fauna. Barrio-Amorós and Narbaiza (2008) made similar comments on this case. Podocnemis lewyana.—This species was reported from Venezuela based on a single specimen found in a bend of the Tarra River, south of Maracaibo Lake, near the town of Casigua (Pauler & Trebbau 1995). Podocnemis lewyana is endemic to the Magdalena River, Colombia, with populations decreasing due to poaching. Three of us (GR, TB & CBA) conducted field studies on Chelus fimbriatus in the Maracaibo Lake Basin (Rivas et al. 2007) and interviewed the farmer who caught the original specimen behind his house along the Tarra River. That river is often used by Colombians to bring food supplies and they might very well bring turtles as well. It was the first and only occasion the farmer saw such a turtle and interviews with other local people show no familiarity with P. lewyana. No additional specimen has ever been reported, and apparently no population established successfully in Venezuela, therefore we do not consider the species as part of the herpetofauna of Venezuela. Order SQUAMATA Amphisbaena spurrelli.—This species was erroneously cited from Venezuela by Donoso-Barros (1968) because the author mistakenly synonymised A. rozei under A. spurrelli. Several authors followed this arrangement (see La Marca 1997; Péfaur & Rivero 2000). Amphisbaena spurrelli is restricted to the Pacific versant of Colombia and Panama, west of the Andes, while A. rozei is known from the Guayana region in Venezuela (thus well east of the Andes). Gans and Mathers (1977), and more recently Vanzolini (2002), showed substantial morphological differences between these species. Anolis frenatus.—Although this species has repeatedly been included as part of the Venezuelan herpetofauna, no voucher specimen exists to confirm its presence in the country. FIGURE 5. Anolis extremus, an adult male from eastern Caracas, Venezuela. Photo by Luis A. Rodriguez. 34 · Zootaxa 3211 © 2012 Magnolia Press RIVAS ET AL. Anolis gibbiceps.—This species was described based on a single female from “Caracas” (Cope 1864). Anolis gibbiceps was subsequently reported from northeastern South America, northern Venezuela and Guyana (Burt & Burt 1933; Parker 1935; Donoso-Barros 1968; Peters & Donoso-Barros 1970), but none of these authors listed specific localities other than that of the holotype. Anolis gibbiceps is closely allied to A. fuscoauratus (Savage & Guyer 1989). The species was not considered by Williams (1976) in his grouping of South American anoles. The validity of this taxon is highly dubious. Based on the original description, the inclusion of this species in the A. fuscoauratus group does not seem appropriate. Moreover, we have been unable to find additional information about this taxon other than the original and brief description (Donoso-Barros 1968; Peters & Donoso-Barros 1970). Examination of specimens assigned to A. gibbiceps from Venezuela revealed misidentified anoles of other species (e.g. A. squamulatus). Recently, C. McCarthy (NHM) sent us photographs of the holotype (BMNH 1946.8.13.35, formerly 1846.10.28.5, Fig. 6) and informed us that the original catalogue entry (dated 1846) states that the specimen is from Jamaica. Written with the holotype is an added undated comment in the handwriting of Miss A.G.C. Grandison, who worked in the collection between 1951–1984, stating: “type locality given as Caracas in Cope’s description”. It is unclear on which basis the locality was changed from “Jamaica” to “Caracas”, but after examining the photographs of the holotype we observed similarities between that specimen and three of the seven anole species found in Jamaica (A. grahami, A. lineatopus and A. opalinus) and conclude that the holotype indeed belongs to a taxon of Caribbean or Central American origin. Thus, the type locality reported by Cope is likely in error. Because we have not examined the holotype in detail we refrain from assigning it to any particular species. It is clear, however, that this taxon does not belong to the Venezuelan herpetofauna. Anolis roquet.—This species was reported in Venezuela as Anolis roquet extremus (Peters & Donoso-Barros 1970); see our comments about A. extremus in the Introduced species section. Anolis transversalis.—Donoso-Barros (1968) mentioned this species from Venezuelan Amazonas, but there is no voucher specimen to confirm the record. Nor Williams and Vanzolini (1966) or Avila-Pires (1995) considered the species present in Venezuela. Atractus badius.—This species was erroneously recorded from the Coastal Range and the Cordillera de Mérida (Roze 1966; Lancini 1979). According to Hoogmoed (1980) this taxon probably includes several distinct species and A. badius has a limited distribution in the Guiana Shield. It is likely that the specimens cited as A. badius from Venezuela are in fact A. univittatus or A. lancinii, at least those from the Coastal Range records (W. Schargel and P. Passos, pers. comm.). Specimens from the Cordillera de Mérida could belong to an undescribed taxon. The species is not considered in our analysis, or as belonging to the Venezuelan herpetofauna. Coleodactylus meridionalis.—No voucher specimen of this species is known from Venezuela. The inclusion of this taxon in the Venezuelan herpetofauna (Rivero-Blanco 1967) is based on misidentified specimens of C. septentrionalis (Vanzolini 1980; Rivas Fuenmayor & Molina 2001). Coleodactylus meridionalis is restricted to northeastern Brazil (Geurgas et al. 2008). Gonatodes ocellatus.—This species was recorded based on individuals from Isla Margarita (Roze 1964b). Later, Rivero-Blanco (1979) examined these specimens and suggested that they belong to an undescribed species. RiveroBlanco (1979) restricted the distribution of G. ocellatus to the island of Tobago. Gymnophthalmus lineatus.—This species has been reported from Tucacas, Falcón State by Mijares-Urrutia and Arends (2000). Their record is based on a single specimen (Museo de Ciencias Naturales de Caracas 195), and the authors mentioned that its identification needs to be confirmed. Although we could not examine that specimen, we consider very likely that it represents a misidentified specimen of G. speciosus, which is present at the same locality (a possibility also suggested by Mijares-Urrutia & Arends 2000). Gymnophthalmus lineatus is thus not included in our list at this stage, even if, as mentioned below, the species could eventually be found in the Las Aves Archipelago. Micrurus lemniscatus helleri.—This subspecies has often been mentioned from Venezuela and its presence was accepted by Roze (1967, 1983). The southern Amazonas population was assigned to this subspecies, but no voucher is provided (Roze 1987). Cunha and Nascimento (1993) pointed out that meristic characters of M. l. helleri REPTILES OF VENEZUELA Zootaxa 3211 © 2012 Magnolia Press · 35 are similar to those of M. l. lemniscatus, and thus that helleri should be considered a synonym of lemniscatus. Barrio-Amorós and Calcaño (2003) followed this statement, assigning the helleri population of Amazonas and a new one from Barinas to M. l. lemniscatus. Oxyrhopus trigeminus.—The species was recorded from Venezuela (Lancini 1979), but Zaher and Caramaschi (1992) re-identified the original photographs published by Lancini as O. aff. melanogenys. According to MacCulloch et al. (2009) the occurrence of O. trigeminus north to the Amazon River, and thus in Venezuela, remains highly doubtful and we follow these authors recommendation. Pliocercus psychoides.—This species was described from the border between Brazil and Venezuela with an unknown date of collection and collector (Smith & Chiszar 1996). In the original description, the authors stated that the species is probably a mimic of Micrurus p. psyches, known from southern Venezuela and the Guianas. For this reason, they concluded that the only known specimen (holotype AMNH 4433), probably came from southern Venezuela. In a subsequent publication Smith and Chiszar (2001) re-identified the same specimen as P. elapoides aequalis with a probable origin from western central Guatemala. Similarly, in the Reptile Database (Uetz 2011), P. psychoides is considered a synonym of P. elapoides according to a personal communication of V. Wallach to the website. Pliocercus elapoides inhabits southeastern México, Belize, Guatemala, Honduras and El Salvador. Curiously, in the catalogue of AMNH, the specimen catalogued 4433 remains identified as Pliocercus euryzonus, a bicolour species that ranges from Nicaragua to western Ecuador (currently placed in the genus Urotheca) and also includes the problematic locality data “Venezuela, Brazil”. Given the lack of verifiable information, we do not consider that any species or subspecies of the genus Pliocercus occurs in Venezuela. Taeniophallus brevirostris.—This species was mentioned from Venezuela as Rhadinaea brevirostris based on two specimens collected in the Sierra de Perijá, Zulia State (Alemán 1953). Dixon and Michaud (1992) correctly assigned one specimen (MHNLS 399) to Liophis melanotus lamari (see Rivas 2001c), while the second (MHNLS 1298) also proved to be L. m. lamari; see our comments below about species of possible occurrence in Venezuela. Taxonomic, nomenclatural and distributional comments Taxa that most deserve nomenclatural/taxonomic/distributional comments are listed below and are arranged alphabetically. Order TESTUDINES Batrachemys/Mesoclemmys spp.—Bour and Zaher (2005) synonymised the genus Batrachemys as well as two recently described genera Ranacephala and Bufocephala with the genus Mesoclemmys. We follow the proposal of McCord et al. (2001) in considering these four genera distinct. Mesoclemmys thus becomes monotypic (M. gibba). Chelus fimbriatus.—The presence of that species in the Maracaibo Lake Basin has long been controversial. The first mention of C. fimbriatus from the area is probably that in Pritchard and Trebbau (1984), who based the record on a personal communication and did not provide any voucher specimen. Rueda-Almonacid et al. (2007) “confirmed” the presence of an isolated population of this species in the Maracaibo Lake Basin—again without any voucher support—a report further mentioned by Pritchard (2008). It must be highlighted that the mention by Rueda-Almonacid et al. (2007) is also based on a personal communication. During the years 2004–2005, TB, GR and CBA conducted fieldwork in the area in search of C. fimbriatus. More than 50 localities were sampled and many interviews with local people were conducted. Although a few local people stated that the species occurs in the area, being very rarely seen, it was confirmed that no voucher specimen has ever been collected. It is possible that an isolated population inhabits the area, but a collected specimen is needed to confirm this. It should also be noted that Orinocoan turtle species are often kept in farms in the southern Maracaibo Lake area. In case of the discovery of C. fimbriatus specimens in the region, molecular analyses will be needed to determine the exact origin of the population(s) (which could have been imported from the Llanos). 36 · Zootaxa 3211 © 2012 Magnolia Press RIVAS ET AL. Rhinoclemmys flammigera.—Gorzula and Señaris (1999) considered the subspecies R. punctularia flammigera (Paolillo 1985) as a western extreme clinal variant or aberration of R. punctularia punctularia. Barrio-Amorós and Narbaiza (2008) elevated the subspecies R. p. flammigera to full species status based on head pattern and biogeography. Herein we recognize R. flammigera as a species. Trachemys callirostris ssp.—Formerly known as subspecies of T. scripta, two forms of the Neotropical slider turtle inhabit Venezuela, T. c. callirostris and T. c. chichiriviche (Seidel 2002). The subspecies have been differentiated using molecular data (Jackson et al. 2008). Order SQUAMATA Ameiva ameiva.—Considered a polytypic species with 10 subspecies, four of them occurring in Venezuela. The validity of these subspecies was questioned by Vanzolini (1986). Avila-Pires (1995) followed Vanzolini noting that a thorough study of the variation in this species is necessary. Ameiva bifrontata.—Peters and Donoso-Barros (1970) recognized four subspecies of A. bifrontata, two of them from Venezuela, the nominal form on the mainland and A. b. insulana restricted to Los Testigos islands. The main difference presented by Ruthven (1924) to distinguish between the populations was the discontinuity of the brachials and antebrachials in the Los Testigos form. We do not believe that this represents more than a clinal variation and until more extensive and detailed studies of the insular form are made, we prefer to treat it as a synonym of the nominal mainland subspecies. Ameiva provitaae.—This species is a possible synonym of A. bifrontata and, until now, was not included in any taxonomic study. The characters thought to be unique to diagnose this species (such as a red snout, see García-Pérez 1995a) are present in different populations of A. bifrontata (GU, unpubl. data). Additional data are needed to clarify the status of this species. FIGURE 6. Holotype of Anolis gibbiceps (BMNH 1946.8.13.35, formerly 1846.10.28.5). Photo by Colin McCarthy. REPTILES OF VENEZUELA Zootaxa 3211 © 2012 Magnolia Press · 37 Anolis species.—The taxonomic status of the genus Anolis sensu lato has been unstable and in constant change. Molecular data (Nicholson 2002) indicate that within Anolis there is a distinct clade (Norops) morphologically characterized by having the autotomy septa lying anterior to anteriorly directed transverse process (Etheridge 1960). However, the other clade (Anolis) is not monophyletic and, although the name Norops is recognized by several authors, we refrain from doing so as this would render the remaining anoles a paraphyletic group. The monophyletic status of Anolis (including Norops) has been recently reassessed based on osteology, internal anatomy, chromosomes, molecular data, allozymes, and immunology (Poe 2004). Anolis biporcatus.—The species is reported for the first time from the Maracaibo Lake Basin based on MBLUZ 992, a specimen collected in a gallery forest along the Palmar river (Km 75 on the road Maracaibo-Machiques, Zulia state, Venezuela). Previous records in Venezuela are from the Mountain Range of Perijá and the Mountain Range of Mérida (Rivas Fuenmayor & Barrio-Amorós 2003). FIGURE 7. Adult male of Anolis bonairensis (FMNH 2684) in lateral (upper) and ventral (below) views, from an undetermined locality in Las Aves Archipelago, Venezuela. Photo by Kathleen Kelly. 38 · Zootaxa 3211 © 2012 Magnolia Press RIVAS ET AL. Anolis bonairensis.—Meek (1910) reported a specimen (FMNH 2684, Fig. 7) as A. alligator from Las Aves Archipelago. GU examined this specimen, which indeed agrees in most diagnostic characters with A. bonairensis. We acknowledge the presence of this species in Las Aves Archipelago, but stress that it needs to be formally confirmed by additional material. Anolis chrysolepis vs Anolis nitens.—The nomenclatural history of these species has been controversial (see Myers & Donnelly 1997, Myers 2008, Cadle 2009 for further details). We agree with these authors and no longer recognize the name Anolis nitens. D’Angiolella et al. (2011) reviewed the Anolis chrysolepis species group based on morphology and molecular data and elevated all subspecies of A. chrysolepis to species status. The species present in Venezuela is thus A. planiceps (type locality Caracas, Venezuela). Anolis eewi.—Vanzolini and Williams (1970) synonymised this species with A. chrysolepis. Gorzula and Señaris (1999) noted that the species is distinguished from A. chrysolepis by shorter legs. Myers and Donnelly (2008) synonymised the species with A. chrysolepis again. We believe that Anolis eewi is a valid species, but until new data are obtained, A. eewi is not included in the list presented herein. Atractus tamessari.—This recently described species (Kok 2006) was known only from Kaieteur National Park, western central Guyana. In the description of Atractus surucucu from Roraima State in Brazil, Prudente and Passos (2008) cited two specimens of A. tamessari from Venezuela in their list of material examined (MHNLS 15124 from Uei-tepui and MHNLS 5950 from “El Dorado-Santa Elena de Uairen”). Since Prudente and Passos (2008) erroneously reported A. tamessari as having 17 dorsal scales rows (instead of 15) the exact identity of these museum specimens is doubtful. Only one of these individuals was available to us, MHNLS 15124, which is a juvenile female of an Atractus species having 15 dorsal scales rows that fits well the description of A. tamessari. We thus formally report the presence of A. tamessari for the first time in Venezuela and expand its known distribution ca. 130 km SWW. The specimen listed as A. tamessari from “El Dorado-Santa Elena de Uairen” by Prudente and Passos (2008) should be better examined to ascertain its identity. Atractus univittatus/fuliginosus.—The original description of A. fuliginosus was based on a single specimen from “200 milles of Caracas”, Venezuela and the status of that species remains unclear (as well as the precise type locality). Atractus fuliginosus was later recorded from the northeastern part of the country (Cerro Turimiquire), but that population has since been described as A. matthewi (Markezich & Barrio-Amorós 2004). Adding some more confusion, in their description of Atractus eriki, an Andean species, Esqueda et al. (2005a) mentioned a specimen of A. fuliginosus from San Juan de Los Morros, a locality lying in the Central Coastal Range with which they compared their new taxon. Surprisingly, these authors did not compare A. eriki with A. univittatus (even if it is listed in their material examined), despite the fact that both species possess 17-17-17 dorsal scale rows and that the localities provided for the A. univittatus specimens they examined (Guanare and Barinitas) are closer to the Venezuelan Andes than San Juan de Los Morros. It is not clear whether Esqueda and colleagues considered univittatus a synonym of fuliginosus, but it should be noted that if Coluber fuliginosus Hallowell 1845 and Rhabdosoma univittatus Jan 1862 are synonyms, the name fuliginosus would have priority. We unfortunately did not examine the holotype of A. fuliginosus and cannot confirm or infirm this possibility. No additional specimen of A. fuliginosus has been collected in recent years (Roze 1966; Lancini 1979) and a revision of the type material of A. fuliginosus compared to A. univittatus is badly needed to resolve this issue. Bachia flavescens complex.—Dixon (1973) recognized two species in the B. flavescens group, each with two subspecies: B. flavescens flavescens, B. f. schlegeli, B. monodactylus monodactylus and B. m. parkeri. Hoogmoed (1973) suggested that B. monodactylus is a synonym of B. cophias. Dixon (1973) distinguished the subspecies of each species based on “weak” and variable characters. According to Dixon (1973) few characters distinguish B. flavescens from B. monodactylus (B. cophias sensu Hoogmoed 1973) and additional material should attest that the two species are conspecific. Avila-Pires (1995), concluded that B. flavescens is a monotypic, highly variable species. Kizirian and McDiarmid (1998) considered that the variation in what is known as B. flavescens is impressive and that the taxon should be considered as a species complex. We agree with Kizirian and McDiarmid (1998) and consider Bachia flavescens to be a species complex in need of revision. REPTILES OF VENEZUELA Zootaxa 3211 © 2012 Magnolia Press · 39 Bachia heteropa ssp.—Bachia heteropa is a polytypic species composed of five subspecies, four of which are present in Venezuela. Populations of the genus Bachia in northern Venezuela, Trinidad, Tobago, Grenada, and the Grenadines were referred to six separate taxa (B. h. heteropa, B. h. alleni, B. h. trinitatis, B. h. lineata, B. h. marcelae and B. h. anomala) (Dixon 1973). Burt and Burt (1933) synonymised B. anomala (from El Mene, Falcón State) with B. lineata. Thomas (1965) considered B. trinitatis to be a subspecies of B. alleni. Later, Donoso-Barros (1968) considered B. marcelae to be a subspecies of B. lineata, retaining B. heteropa and B. alleni as separate species. The revision of the genus by Dixon (1973) provided a better understanding of the group. Dixon noted that there seems to be a progressive reduction in size and loss of prefrontal scales as well as toes from east to west. After examining most available specimens, Dixon (1973) considered all populations in northern Venezuela, Trinidad, Tobago, Grenada and Grenadines to be B. heteropa, which was the oldest name available for this group of lizards. Dixon considered the east to west cline an adaptation to more fossorial habits. Intermediate specimens between B. h. heteropa and B. h. trinitatis are known from eastern Venezuela but intermediates between B. h. lineata and B. h. heteropa are unknown although both subspecies have been recorded from nearby areas (B. h. heteropa from la Guaira, Vargas State and B. h. lineata from Distrito Federal, Caracas). More material is definitely needed to clarify the status of these subspecies. We consider that the significant amount of variation among populations of this taxon could indicate a complex of species, but a taxonomic revision of this taxon is out of the scope of this paper and we decide to treat B. heteropa as a monotypic taxon until this situation is resolved. Bothriechis schlegelii.—This species was reported from Ureña (Pifano et al. 1950), a semi-arid area in the Táchira depression, Táchira State. Pifano et al. (1950) provided a photograph of an individual, but no catalogue number or name of a collection housing a voucher specimen. The species has been cited from a Colombian locality nearby (Campbell & Lamar 2004), and despite the absence (loss?) of a voucher specimen we consider this species as belonging to the Venezuelan herpetofauna, stressing that a new voucher should confirm its presence. Bothriechis schlegelii usually inhabits tropical and mountain rainforest. It must be noted that Sandner-Montilla (1965) apparently also mentioned the species from the Amazonas State (as stated in Campbell & Lamar 2004). Campbell and Lamar (2004) considered that these records are likely erroneous and that they must be confirmed. We were unable to obtain a copy of Sandner-Montilla (1965), but we read a copy of the second edition of that booklet (SandnerMontilla 1975), in which there is no mention of B. schlegelii from the Amazonas State. We assume that the previous records were indeed erroneous and were removed by the author in the second edition of his work. The Bothrops asper-colombiensis-isabelae problem.—For many years a great deal of controversy has arisen about the proper name to be given to the Bothrops species inhabiting the lowlands of the Venezuelan Coastal Range. One of these names is B. colombiensis, used by numerous authors for a species present north of the Orinoco River (Lancini 1979). The type locality, “Republic of Colombia, within two hundred miles of Caracas, Venezuela” could be any locality in northern Venezuela instead of Colombia because the closest border with Colombia is located 700 km SW (approximately 450 miles) from Caracas. Sandner-Montilla (1979a) synonymised B. colombiensis with B. lanceolatus, the latter currently considered endemic to the island of Martinique, Lesser Antilles (Campbell & Lamar 2004; Fenwick et al. 2009), which is 437 km off mainland Venezuela. The same author later described B. l. aidae (Sandner-Montilla 1981), based on a specimen from the Colección de ejemplares vivos de la Familia Crotalidae del Serpentario del Instituto Venezolano de Ofidiología, Caracas (Collection of living specimens of the family Crotalidae of the Serpentarium of the Venezuelan Institute of Ophidiology, Caracas) from “Selvas de Guatopo, Estado Miranda”. Sandner-Montilla (1990) also described B. l. nacaritae from “Cariprima, N. de Valencia". “Cariprima” is not found on any available map, but both Estado Miranda and Valencia are in the Coastal Range. Both subspecies were considered synonyms of B. atrox by Campbell and Lamar (2004), although they probably meant B. asper since the Coastal Range is outside the geographic distribution of B. atrox (Campbell & Lamar 2004: 377, map 57), but inside the geographic distribution of B. asper (Campbell & Lamar 2004: 372, map 56). In any case, we consider the populations from Valencia and Guatopo as B. asper rather than B. atrox, except the population from the cloud forest that is B. venezuelensis. Johnson and Dixon (1984) considered B. colombiensis a synonym of B. atrox, but at least four species were involved under what they named B. atrox (as stated by Campbell & Lamar 2004). Sandner-Montilla (1979b) described an additional species from Guanare, in the foothills of the Venezuelan Andes: Bothrops isabelae (also based on living specimens kept in captivity under number “Bi No. 1”). Markezich and Taphorn (1993) in a study on the variation of some populations of Venezuelan Bothrops concluded that B. isabelae is not valid and synonymised 40 · Zootaxa 3211 © 2012 Magnolia Press RIVAS ET AL. it with B. atrox. Fenwick et al. (2009) in the first attempt to use both morphological and molecular evidence to study South American pit vipers, included sequence fragments of B. isabelae obtained from Wüster et al. (2002) (no specific locality was provided) in their analyses. In all analyses by Fenwick et al. (2009), B. isabelae falls together with B. atrox, with a seemingly low genetic distance. Nevertheless, Fenwick et al. (2009) included B. isabelae in their list of Bothrops species (therefore apparently recognizing it as a valid taxon). Some authors (e.g. Lancini 1979; Navarrete et al. 2009) still use B. colombiensis to refer to the most common pit vipers that inhabit northern Venezuela without any justification. These authors also consider B. isabelae to be a valid species (see Navarrete et al. 2009). We do not consider B. colombiensis, B. isabelae, B. l. nacaritae, and B. l. aidae as valid taxa until comparative systematic analyses involving both morphological and molecular evidence from specimens from the type localities are conducted. We follow Campbell and Lamar (2004) in the use of B. asper and B. atrox for these populations of northern Venezuela. Colubridae/Dipsadidae.—Two papers on the molecular phylogeny of the Colubroidea appeared recently, both suggesting changes to the current taxonomy of this group of snakes (Hedges et al. 2009; Zaher et al. 2009). These papers support the recognition of the subfamilies Xenodontinae and Dipsadinae within the family Dipsadidae Bonaparte, 1838 (including also the new subfamily Carphophiinae). Other changes suggested by these authors involving genera occurring in Venezuela are the resurrection of the genus Lygophis and the synonymisations of Lystrophis and Waglerophis with Xenodon, and of Erythrolamprus with Liophis. Curcio et al. (2009a) mentioned that the proposal of synonymising Erythrolamprus with Liophis is premature in view of the insufficient evidence provided by Zaher et al. (2009), proposing maintenance of the traditional recognition of both names as valid until new data become available based on a more comprehensive sampling with proper technical supporting evidence (e.g. inclusion of type species). Curcio et al. (2009a) also mentioned a similar problem with the resurrection of Lygophis, pointing out that such a taxonomic change should have been guided by reference to the type species of the genus, e.g. Herpetodryas lineatus Schlegel (=Liophis lineatus), which was not sampled by Zaher et al. (2009). However, we consider the arguments provided by Zaher et al. (2009) for the recognition of Lygophis sufficient for the resurrection of that genus, which is adopted in our list. Although Zaher et al. (2009) regarded Xenoxybelis as a synonym of Philodryas, we are not convinced by their arguments and prefer to wait for more analyses involving a larger number of species of the genus Philodryas. Vidal et al. (2000) also found Xenoxybelis nested within Philodryas. However, as mentioned by these authors, a more detailed phylogenetic analysis of the newly extended genus Philodryas might show the necessity of a partition of some Philodryas and the recovered monophyletic subunits. Other results of Zaher et al. (2009) involve the allocation of most West Indian snakes to the tribe Alsophiini, a group also studied by Hedges et al. (2009) who proposed a new reclassification for these snakes. Hedges et al. (2009) supported some of the changes proposed by Zaher et al. (2009), one of them being the partitioning of Colubridae. According to their proposal, the following subfamilies and genera are now considered as belonging to the family Dipsadidae: Dipsadinae: Atractus, Dipsas, Imantodes, Leptodeira, Ninia, Plesiodipsas, Sibon and Urotheca. Xenodontinae: Thamnodynastes (Tachymenini), Taeniophallus (Echinaterini), Clelia, Oxyrhopus, Phimophis, Pseudoboa, Siphlophis (Pseudoboini), Philodryas (Philodryadini), Hydrodynastes (Hydrodynastini), Hydrops, Helicops, Pseudoeryx (Hydropsini), Liophis, Erythrolamprus, Umbrivaga and Xenodon (Xenodontini). Dipsadidae incertae sedis: Enulius. Other genera currently remain in Colubridae. Cercosaura phelpsorum.—Euspondylus phelpsi was originally described by Lancini (1968) on the basis of a single female supposedly from Cerro Jaua (corrected to Cerro Sarisariñama by Steyermark & Brewer-Carías 1976). In his revision of the genus Prionodactylus, Uzzell (1973) did not reallocate E. phelpsi to Prionodactylus because a double widened row of gular scales—one of the diagnostic characters of the genus Prionodactylus according to Uzzell—was not mentioned in the original description. In 1996, Myers and Donnelly described a new species, E. goeleti from Cerro Yavi, Amazonas State, which according to the authors appears to be closely related to E. phelpsi but differs from it by having a pale vertebral stripe distinctly broadening posteriorly (vs maintaining the same width), greenish white ventral colouration (vs slate gray with black speckling), and distinctly keeled dorsal scales (vs weakly keeled). These authors also corrected the name of the species from E. phelpsi to E. phelpsorum (Myers & Donnelly 1996). Gorzula and Señaris (1999) reallocated the species to the genus Prionodactylus without providing any argument, and proposed to synonymise P. goeleti with P. phelpsorum based on (1) the fact that all the scale REPTILES OF VENEZUELA Zootaxa 3211 © 2012 Magnolia Press · 41 counts given by Lancini fall within the variation given by Myers and Donnelly (1996), (2) the subjectivity of the difference between the weakly keeled scales of P. phelpsorum and the distinctly keeled scales of P. goeleti, and (3) the likely misinterpretation of the ventral colouration and shape of the middorsal stripe. Soon after, Mijares-Urrutia (2000) reported the holotype of P. phelpsorum lost and concluded that in the absence of a neotype and additional material allowing further comparisons P. goeleti should be removed from the synonymy of P. phelpsorum. Myers and Donnelly (2001) partly agreed with Gorzula and Señaris (1999) mentioning that although neither Euspondylus nor Prionodactylus have enough characters that uniquely define each genus, the allocation of E. phelpsorum in Prionodactylus “has the practical advantage of associating them in the same group with the similar-appearing Andean Prionodactylus vertebralis”. However, Myers and Donnelly (2001) disagreed with Gorzula and Señaris (1999) stating: “In allocating the name Euspondylus goeleti to the synonymy of Prionodactylus phelpsorum, Gorzula and Señaris apparently confused ontogenetic variation with the kind of extensive intraspecific variation that is not correlated with age, sex or geography”. Myers and Donnelly (2001) insisted again on the differences in width between the vertebral stripe present in P. phelpsorum and that of P. goeleti, pointing out, with the support of photographs, that the vertebral stripe of the former species does not widen posteriorly but is equally narrow, as it is not the case in all known specimens of P. goeleti (less pronounced in juveniles). Myers and Donnelly (2001) considered the difference in ventral colouration as a secondary diagnostic character and noted: “But we took Lancini at face value that the throat and venter of the female specimen of phelpsorum were slate gray in life, and assumed that if the ventral ground colour in life had been pale he would have said so. If, however, he had misleadingly extrapolated ventral colour from the preserved specimen, it would be a different matter since female goeleti became light gray in preservative...”. Myers and Donnelly (2001) also noted that the two species belong to geographically remote populations, reinforcing their arguments. In her recent revision of the genera Cercosaura, Pantodactylus, and Prionodactylus, Doan (2003) concluded that P. goeleti shows variation in the size of the gular scales. One of the specimens examined by Doan exhibited a complete double row of gulars, another had no difference in size between the midventral gulars and the ventrolateral gulars, and another one had a double row widening posteriorly only. Doan (2003) also pointed out that this can be seen in the photographs provided by Myers and Donnelly (1996, 2001). Doan (2003) concluded: “I would be hesitant to decide on its generic status except for its obviously close relationship with P. nigroventris... a species that possesses all the diagnostic characters of Prionodactylus. Based on these similarities, I retain this species in Prionodactylus”. Doan (2003) also synonymised the genera Pantodactylus and Prionodactylus with Cercosaura and considered C. goeleti a junior synonym of C. phelpsorum. We examined four museum specimens identified as Cercosaura phelpsorum, three from the type locality of C. goeleti (MHNLS 11135, MHNLS 11141−42, all collected at 2550 m elevation), and one individual from Cerro Huachamacari, a mountain located about 200 km SWW from Cerro Sarisariñama and about 230 km S from Cerro Yavi (MHNLS 12518, collected at 1700 m elevation), and an unidentified Cercosaura from Cerro Autana (Fuentes & Rivas Fuenmayor 2000), a mountain located about 220 km NW from Cerro Sarisariñama and about 180 km SW from Cerro Yavi (MBUCV 7114, collected at 1450 m elevation). We could not find any pertinent morphological difference between these five preserved specimens and the description of C. goeleti. The degree of keeling is variable among them, the middorsal-scale counts varied between 38–42 (variation not related to geographical distribution), the widening of the vertebral stripe is always present and seems variable and related with age, from 3 (one juvenile) to 4–5 scales (four adults) in the inguinal region (as also highlighted by Myers & Donnelly 2001). Unfortunately ventral colour in life is unknown, but it is similar among all preserved specimens, except the juvenile. Because none of those specimens has the vertebral stripe exactly as described by Lancini (1968) in C. phelpsorum, the state of that stripe apparently remains the only obvious morphological difference between C. goeleti and C. phelpsorum. In our opinion, this single character is not sufficient to separate species and might well be considered as interpopulational variation. This is strengthened by the fact that “C. goeleti” has a much wider range than previously thought, and that if the species is present in Cerro Autana and Cerro Huachamacari there is no reason that it would be absent from Cerro Sarisariñama, which lies in the same biogeographic area. Our new distributional data are additional arguments to agree with Gorzula and Señaris (1999) and Doan (2003) concluding that because of the absence of convincing diagnostic characters between C. goeleti and C. phelpsorum the former should be considered a junior synonym of the latter. However, new collection efforts are needed in the Jaua-Sarisariñama area in order to better understand the inter-and intrapopulational variation of C. phelpsorum since the most recent herpetological expedition to Sarisariñama (Barrio-Amorós & Brewer-Carías 2008) has been unsuccessful in finding the species. 42 · Zootaxa 3211 © 2012 Magnolia Press RIVAS ET AL. Cnemidophorus lemniscatus ssp.—Clearly a complex of species. Reeder et al. (2002) placed C. l. splendidus and C. arenivagus as sister taxa, suggesting that a specific status of C. l. splendidus deserves re-evaluation. Markezich et al. (1997) previously stated: “...future work may well result in elevating C. l. splendidus and other forms to recognition as species also”. C. J. Cole (pers. comm.) is currently working at the recognition of C. l. splendidus as a full species. Coluber mentovarius ssp.—A species formerly placed in the genus Masticophis, a genus that has been synonymised with Coluber several times (Savage 2002). Recent phylogenetic data corroborate that Masticophis cannot be separated from Coluber, and thus the former must be treated as a junior synonym of the latter (Utiger et al. 2005). Herein, we adopt these taxonomic changes although they have not been universally accepted (Collins & Taggart 2008). There is considerable variation within each of the Venezuelan subspecies, but they still appear to be well differentiated and separated geographically. Our data (unpublished) suggest that C. m. centralis has a same pattern of geographic distribution as other lowland colubrid species, such as Drymarchon caudomaculatus and Thamnodynastes paraguanae, which could be used as models to test biogeographic hypotheses in northern South America. The population of this subspecies in Panama should be re-evaluated, and the populations in Colombia and Venezuela assigned to C. m. centralis might deserve full species status. Crotalus maricelae.—This species was described from an intra-Andean valley in the Cordillera de Mérida (GarcíaPérez 1995b). Crotalus maricelae was diagnosed based on cephalic scutellation, colour pattern and reduced adult size (García-Pérez 1995b, Vanzolini & Calleffo 2002; Campbell & Lamar 2004). The original description is very brief and the species is virtually indistinguishable from C. durissus cumanensis. Esqueda et al. (2001) suggested that C. maricelae is a nomen nudum and that this population does not deserve recognition because all diagnostic characters fall within the variation range of C. d. cumanensis. La Marca and Soriano (2004) considered Crotalus maricelae a valid taxon, using the same characters mentioned in the original description. This species is not included in the list and we follow Campbell and Lamar (2004) in considering this taxon a synonym of Crotalus durissus. Crotalus pifanorum.—The taxonomy of this species has been controversial because of the imprecise original description and the lack of type specimens. Originally described from the Llanos in southern Guárico (SandnerMontilla 1980), C. pifanorum has been considered a subspecies of C. durissus by Campbell and Lamar (2004). In an undergraduate unpublished dissertation, Pérez-Bidó (1992) compared pifanorum and cumanensis (karyotype, protein electrophoresis and microdermatoglyphs) and supported the recognition of C. pifanorum as a valid species. Several years later, the thesis was published (Pérez et al. 1997), but without providing a list of specimens examined and their geographic provenance. Pending additional data we still consider C. pifanorum a subspecies of C. durissus. Crotalus vegrandis.—The taxonomic history of C. vegrandis has been controversial as well. Originally described as a distinct species by Klauber (1941), the same author (Klauber 1956) relegated it to a subspecies of Crotalus durissus. Nevertheless, this arrangement was not followed by all authors, and C. vegrandis is often treated as a valid species (Lancini 1967; Peters & Orejas-Miranda 1970). In their recent revision, Campbell and Lamar (2004) treated C. vegrandis as a subspecies of C. durissus. We consider C. vegrandis a full species mostly based on the following morphological differences: smaller length, peculiar colour pattern composed of gray and/or reddish brown ground colour with large white flecks distributed as irregular rings (vs rhomboidal blotches in C. durissus). Crotalus vegrandis has an isolated distribution in the lowlands of Maturín and Anzoátegui States, northeastern Venezuela. Dipsas copei.—We follow Harvey (2009) in considering that D. copei is not a synonym of Leptognathus incertus (= D. incerta) and that D. incerta could be a valid species related to D. praeornata as first noted by Amaral (1929a, 1929b) and subsequently by Harvey (2009). Dipsas cf. indica.—This species is tentatively included in the Pantepui region based on a specimen reported from La Neblina (1515 m) by McDiarmid and Paolillo (1988) and by McDiarmid and Donnelly (2005). We did not REPTILES OF VENEZUELA Zootaxa 3211 © 2012 Magnolia Press · 43 examine that individual and its exact identity thus remains unconfirmed. The maximum known elevation reported for D. indica is 1000 m (see Natera-Mumaw & Battiston 2008). Dipsas peruana/D. latifrontalis.—Dipsas latifrontalis was originally described from Aricagua in the Venezuelan Andes (Boulenger 1905) and later recorded from some localities in Ecuador and the Venezuelan Coastal Range (Peters 1960; Esqueda et al. 2001). Harvey and Embert (2009) resurrected the name D. praeornata for the Venezuelan Coastal Range population and relegated D. latifrontalis to a synonym of D. peruana. The status of the Ecuadorian populations assigned to this species is unclear (Cadle 2005). We provide here preliminary data on the specimen CVULA 7883 from San Isidro, Estado Barinas, 1400 m, considered the second known specimen of D. peruana (Fig. 8) from Venezuela (along with the holotype of D. latifrontalis at the BMNH). The specimen has 1515-15 dorsal scales, 192 ventral scales, 109 subcaudal scales, 8 supralabials and 11 infralabials. FIGURE 8. Juvenile specimen of Dipsas peruana from San Isidro, Barinas (CVULA 7883). Photo: César L. Barrio-Amorós. Dipsas pratti.—This species was described based on a female from Medellin, Colombia at an elevation of 1700 m (Boulenger 1897). Four more species of Dipsas were later described (Cope 1899; Prado 1940, 1941; Werner 1916) and were found to be juveniles of the same species (the differences reported only reflected ontogenetic changes) and therefore synonymised with D. pratti (Peters 1960). However, the species’ systematics and natural history still remain unknown. The species is currently known only from a few specimens from the Cordillera Central and the Cordillera Oriental in Colombia, where it was recently reported in the departments of Santander and Bolívar (Moreno-Arias et al. 2006). Unfortunately these authors do not provide any information on the morphological variation and natural history. Recently, several specimens assigned to D. pratti were collected on the Venezuelan side of the Sierra de Perijá (Estado Zulia) at 1600 m. A redescription of this species including the Venezuelan specimens is in press (Barros et al. in press). Epicrates maurus.—Considered a subspecies of E. cenchria by some authors (e.g. Lancini & Kornacker 1989; Perez-Santos & Moreno 1988) or full species by others (e.g. Chippaux 1987; Gorzula & Señaris 1999; BarrioAmorós & Díaz de Pascual 2008). Recently, Passos and Fernandes (2008), on the basis of external morphology, osteology and hemipenial characteristics, showed that E. maurus is a distinct species. 44 · Zootaxa 3211 © 2012 Magnolia Press RIVAS ET AL. Gekkonidae.—Kluge (1967) considered five subfamilies in that family. Sphaerodactylinae was recently reviewed and elevated to family status (Sphaerodactylidae) containing the New World genera Coleodactylus, Gonatodes, Lepidoblepharis, Pseudogonatodes and Sphaerodactylus, and the Old World genera Saurodactylus, Quedenfeldtia, Aristelliger, Teratoscincus, Pristurus and Euleptes (Gamble et al. 2008a). Gamble et al. (2008b) recovered another monophyletic trans-Atlantic gecko clade (Phyllodactylidae) containing, among others, the genera Phyllodactylus and Thecadactylus. The Venezuelan species of Hemidactylus (native and introduced) remain in the family Gekkonidae. Gonatodes superciliaris.—Barrio-Amorós and Brewer-Carías (2008) described G. superciliaris as a Sarisariñamatepui endemic. The new species is morphologically indistinguishable from G. alexandermendesi (Cole & Kok 2006) and G. superciliaris is likely a junior synonym of this species. However, since preliminary phylogenetic analyses do not clearly corroborate this fact (see Schargel et al. 2010) and in the absence of additional data we still include the species in our list. Gonatodes vittatus ssp.—Roze (1956) described an insular taxon, G. vittatus roquensis, from El Gran Roque, archipiélago de los Roques, Venezuela. One of us (GR) noted that the holotype (MHNLS 1031) is an adult specimen of G. antillensis (MHNLS 1031, erroneously cited as MNHLS 10800). The remaining series of paratypes deposited in MHNLS (1032–1043) and MBUCV (MBUCV 1906–1909) are G. aff. vittatus. Thus, we do not consider roquensis as a valid subspecies, but wish to stress that these insular populations should be examined using molecular data to confirm their taxonomic identity. Helicops hogei.—Here we recognize the taxon as distinct, but a reassessment of the species is suggested in order to support its validity (see Rossman 2002). Hydrops martii.—We report for the first time H. martii in Venezuela from the conjunction of the Casiquiare arm and the Siapa river in southern Amazonas State, based on photographs taken by CBA in 1998 during a fluvial expedition in search of turtles (Fig. 9) (Barrio-Amorós & Narbaiza 2008). The specimen was not collected due to the lack of permits at that time. Based on the available photographs, the specimen has 173 ventrals, and the typical pattern of the species, consisting of black rings of 1–2 scales wide surrounded by an incomplete one scale wide ring and separated from the other by a reddish ring of 2–3 scales wide. The photographs agree well with other published illustrations of the species (Bartlett & Bartlett 2003; Campbell & Lamar 2004). We consider the pictures, kept in the collection of Fundación Andigena (FA 184–85), as photographic vouchers. Lampropeltis triangulum andesiana.—The occurrence of Lampropeltis triangulum in Venezuela was reported by Roze (1966) and subsequent workers (Lancini 1979; Kornacker 1999) as the subspecies L. t. micropholis. Barrio and Navarrete (1999) clarified the subspecies identity of the Venezuelan specimens and considered them to belong to L. t. andesiana. Leptophis ahaetulla ssp.—Three subspecies of L. ahaetulla have been recorded from Venezuela: L. a. ahaetulla, L. a. coeruleodorsus, and L. a. occidentalis (Lancini 1979; Albuquerque 2009). Leptophis a. coeruleodorsus has a wide distribution throughout the lowlands of Venezuela, east of the Andes, north and south of the Orinoco River and is also present on Isla Margarita. Leptophis a. ahaetulla in Venezuela was formerly considered to represent a distinct subspecies, L. a. copei. Both taxa were shown to be identical by Albuquerque (2009), and the name ahaetulla has precedence over copei. In Venezuela Leptophis a. ahaetulla is known from few specimens collected in the southern part of the Amazonas State. Leptophis a. occidentalis is present in north and northwestern Venezuela west of the Andes. This last form is the most morphologically differentiated among the subspecies found in Venezuela. The taxonomic status of this subspecies is still poorly understood and some populations have enough unique features to deserve specific status. N. R. de Albuquerque (pers. comm.) is currently working on a systematic revision of Leptophis. REPTILES OF VENEZUELA Zootaxa 3211 © 2012 Magnolia Press · 45 FIGURE 9. The only known specimen of Hydrops martii from Venezuela found dead on a beach at the conjunction of the Casiquiare arm and Siapa river in southern Amazonas State in January 1998. Photo: César L. Barrio-Amorós. Liophis miliaris.—A specimen of L. miliaris from the Amazonas State (Fuentes 2003) is herein re-identified as Liophis cf. zweifeli (see below) because, in addition to several colour pattern characteristics, it possesses a single apical pit in some dorsal scales and presents a low number of ventral scales (134). None of these characters has ever been found in any L. miliaris population (see account for L. zweifeli). Liophis miliaris is known in Venezuela from Bolívar State (Kornacker et al. 2002; Myers & Donnelly 2008). Liophis zweifeli.—We consider this species distinct from the L. reginae complex. Liophis zweifeli differs from L. reginae (meristic and colour characters taken from Dixon 1983a) in having a salt-and-pepper dorsal pattern (vs dorsum with dense pale and dark paravertebral flecking in L. reginae) and in having a higher number of subcaudal scales (69−88 vs 55−78 in L. r. reginae). Both species are forest snakes. Liophis zweifeli is found mainly throughout the Cordillera de Mérida and the Coastal Ranges in Venezuela, although some specimens of L. cf. zweifeli are known from localities in southern Venezuela. That species has been previously confused with individuals of L. miliaris from Bolívar, south of the Orinoco River (Kornacker et al. 2002). Dixon (1983a) recorded a specimen of L. zweifeli (as L. reginae zweifeli) from Cerro Yapacana in central Amazonas, Venezuela. We examined an additional specimen from the same locality (EBRG 1156, cited in Fuentes 2003), which fits generally well the description of L. zweifeli, except that it has fewer subcaudal scales, although the very tip of the tail is missing (47 vs 78–86 fide Roze [1966] and 69–88 fide Dixon [1983a]). A re-evaluation of this taxon and a revision of the L. reginae species complex are needed to properly determine the status of this population in the state of Amazonas. Oxyrhopus formosus/occipitalis.—We follow MacCulloch et al. (2009) and consider the specimens reported as O. formosus from Venezuela to be O. occipitalis. Oxyrhopus melanogenys (Fig. 10).—Lynch (2009) described Oxyrhopus vanidicus from Colombia. According to the original description, the new species only slightly differs in colour pattern from the very similar O. melanoge- 46 · Zootaxa 3211 © 2012 Magnolia Press RIVAS ET AL. nys. Lynch (2009) stated that some populations formerly assigned to O. melanogenys and O. aff. melanogenys from northern South America are Oxyrhopus vanidicus. We examined four specimens (EBRG 1536, 2069, MHNLS 11967, 11998) from Amazonas and Bolívar States in southern Venezuela, which fall within the variation reported for O. vanidicus. However, we could not find consistent differences between O. vanidicus and O. melanogenys. Pending additional evidence we consider all the specimens previously referred to O. aff. melanogenys and O. trigeminus in Venezuela as O. melanogenys (see also comments under Oxyrhopus trigeminus, and MacCulloch et al. 2009). FIGURE 10. Uncollected specimen of Oxyrhopus melanogenys photographed at night at Tobogán de la Selva near Puerto Ayacucho, Amazonas State. Photo: César L. Barrio-Amorós. Proctoporus cephalolineatus.—García-Pérez and Yustiz (1995) described Proctoporus cephalolineatus, providing a very brief and incomplete description, and suggested that it is closely related to P. achlyens and P. shrevei (P. luctuosus group). Doan and Schargel (2003) doubted that this species belongs to the P. luctuosus group and even rejected the fact that it belongs to Proctoporus because of the presence of prefrontal scales, but that it rather could belong to either Euspondylus or Pholidobolus. Including this species in the probably paraphyletic genus Euspondylus would bring more confusion. Pholidobolus is distributed far from the Venezuelan territory and is still poorly understood (Hillis 1985). The single specimen of P. cephalolineatus could be an aberrant specimen of the geographically close P. inanis, a species from the Andes of Mérida recently described and now in the genus Riama (Doan & Schargel 2003; Doan & Castoe 2005), in which case the name P. cephalolineatus would have priority. Rena dimidiata.—This species very likely occurs in Venezuela, but is not included in our list because no voucher specimen exists. The type locality of R. dimidiata has been restricted to an area within Roraima State, Brazil (close to the border with Venezuela) by Peters & Orejas-Miranda (1970). The first mention of the species in Venezuela was apparently by Lancini (1979), who based the record on Orejas-Miranda (1966, 1969) and cited the species from the country with no voucher mentioned. Based on this report the species was later reported from Venezuela by several authors (e.g. Lancini & Kornacker 1989; La Marca 1997; Péfaur & Rivero 2000). Orejas-Miranda (1966, 1969), however, did not mention R. dimidiata from Venezuela, but in 1970, Orejas-Miranda in Peters and OrejasMiranda (1970) provided the following distribution for the species: “Guianas, northern Brazil and southeastern REPTILES OF VENEZUELA Zootaxa 3211 © 2012 Magnolia Press · 47 Venezuela”. Hoogmoed (1977) stated: “According to Orejas-Miranda (1967) the species occurs in a restricted zone in the border area of Brazil, Guyana and Venezuela, coinciding with the Rupununi savanna and its extensions into Brazil and Venezuela. In 1970 the area is given as being slightly more extensive by the same author [=OrejasMiranda]". Hoogmoed did not explicitly report the species from Venezuela but tried to describe the general area south of Roraima given by Orejas-Miranda and also reported Orejas-Miranda´s 1970 extension of the distribution of R. dimidiata into Venezuela. Interestingly, there is no mention of R. dimidiata from Venezuela in that paper either. A revision of the family Leptotyphlopidae in Venezuela is needed, particularly to elucidate the taxonomic status of the Epictia goudotti-albifrons complex, which includes the population from Isla Margarita, currently placed in the synonymy of E. goudotti. Tantilla melanocephala.—The species is reported from the Pantepui region based on a specimen identified by GR (MHNLS 12339) collected in Cerro Jaua, between 1600-1800 m elevation. Thamnodynastes species.—Ten species of this genus are currently recognized in Venezuela. Although the taxonomy of this group has been largely confusing, resulting in occasional confrontations (e.g. Gorzula & Ayarzagüena 1996 vs Myers & Donnelly 1996) some recent contributions provide a better understanding of that difficult genus (e.g. Bailey & Thomas 2006). Tretioscincus bifasciatus.—Formerly divided into two subspecies, T. b. bifasciatus from northern Caribbean Colombia and T. b. kugleri from Venezuela and Aruba. The main difference between the subspecies appears to be the colour pattern. However, the species seems to show considerable individual variation in the intensity of dorsolateral stripes and ventral spotting. Marcuzzi (1950a) examined specimens from Bobare, Lara, and El Pilar, Sucre and questioned the status of the subspecies T. b. kugleri, arguing that colour variation in a species, which appears to be highly variable in this case, is not recommended in the recognition of subspecies. We agree with and follow Marcuzzi in not recognizing T. bifasciatus kugleri as a valid taxon. Species of possible occurrence A considerable number of reptile species are known from non-Venezuelan localities close to the Venezuelan borders, sometimes within a same biogeographical area and they eventually could be found in Venezuela. In the Serrania de Perijá, the northernmost spur of the Andes between Colombia and Venezuela, the lizards Bachia talpa, and Leposoma rugiceps, as well as the snakes Coniophanes fissidens, Scaphiodontophis venustissimus and Urotheca lateristriga are very likely to be found on the Venezuelan slopes of the mountain range. Most of these species have been collected in Colombian localities geographically close to Venezuela. Numerous colubroid snakes like Atractus variegatus, Dendrophidion bivittatus, Geophis brachycephalus and Helicops danieli as well as the viperid Bothrocophias microphthalmus are likely to be found in the western parts of the state of Táchira, which are a prolongation of the Cordillera Oriental of Colombia. Another snake, the elapid Micrurus sangilensis has been found very close to the Venezuelan border along with the tropidurid lizards Stenocercus santander and S. trachycephalus. The southernmost part of the Venezuelan Guayana is perhaps one of the least studied areas of the country. It is likely that one or more of the following microteiids are present in the country: Gymnophthalmus leucomystax, G. underwoodi, and/or G. vanzoi. Other lizards almost certainly found in this area of Venezuela are Iphisa elegans, Kentropyx borckiana, and Anolis trachyderma. The snakes Atractus surucucu, Dipsas pakaraima and Micrurus pacaraimae also probably occur in the Venezuelan Guayana. The Venezuelan Amazonia, has been even less studied than the Venezuelan Guayana and numerous unrecorded species are suspected to occur there. Anolis transversalis has been mentioned in previous lists (Donoso-Barros 1968; Péfaur & Rivero 2000) with no supporting data (see above), but might be found in this area. Other lizard species likely to be found in the area are Cercosaura argulus, Kentropyx pelviceps, Leposoma guianense, Mabuya bistriata, and Uracentron flaviceps. Several snakes are also very likely to be found in this ecoregion, these include: Atractus poeppigi, Mastigodryas moratoi, Pseudoboa martinsi, and Umbrivaga pyburni as well as the elapid snakes Leptomicrurus scutiventris, L. renjifoi, Micrurus filiformis, M. langsdorfii, the viperid Bothrocophias hyo- 48 · Zootaxa 3211 © 2012 Magnolia Press RIVAS ET AL. prora, and the turtle Rhinemmys rufipes (see an unconfirmed record by Barrio-Amorós & Narbaiza 2008). One of us (CBA) saw a specimen of Dracaena guianensis swimming in the intersection of the rivers Siapa and Casiquiare in January 1998; the individual was not caught nor photographed, so the presence of this species needs confirmation. Last but not least, the numerous islands off the Venezuelan Caribbean coast might also harbour some species found on the neighbouring islands of Curaçao or Bonaire. The Gymnophthalmid lizard Gymnophthalmus lineatus could eventually be found in the Las Aves Archipelago, and the aquatic snake, Pelamis platurus could be found along the northwestern Venezuelan coast, mainly off the Península de La Guajira (Hernández-Camacho et al. 2005).

(2011) resurrected the family Dactyloidae Fitzinger to include the lizards of the genus Anolis sensu lato that were formerly placed in the family Polychrotidae. Gamble (2011) described the genus Chatogekko to include Coleodactylus amazonicus, and Esqueda (2011) described a new Atractus species from northwestern Venezuela (bioregion 6). Finally, Ugueto and Harvey (2011) published a taxonomic revision of Ameiva ameiva in Venezuela where the authors concluded that A. ameiva (sensu lato) in Venezuela comprises at least four evolutionary species and elevated A. ameiva (sensu stricto), A. atrigularis, and A. praesignis to species. Populations from the savannahs of southern Monagas represent a new species that the authors described as A. pantherina. Thus, A. ameiva in Venezuela is distributed through bioregions 10, 12, 13 and narrowly in southern Anzoátegui (here considered part of bioregion 11); A. atrigularis is found through bioregions 8, 9 and 2 (Isla de Margarita); A. praesignis ranges through 3, 4, 6, 7 and 11; the latter bioregion is also the one inhabited by the endemic A. pantherina. According to these new arrangements and species descriptions, the number of reptiles in Venezuela increased to 374 species in 123 genera. Esqueda, L.F.
