Naming
*Northern white-lipped mud turtle – "K. l. leucostomum"⤷ Southern white-lipped mud turtle – "K. l. postinguinale"
"Nota bene": A trinomial authority in parentheses indicates that the subspecies was originally described in a genus other than "Kinosternon".The synonym, "Cinosternon spurrelli" Boulenger, 1913, which is a synonym of "Kinosternon leucostomum postinguinale", was named in honor of British zoologist Herbert George Flaxman Spurrell.
