Systematics of gymnophthalmid lizards

Abstract:

Phylogenetic relationships among members of the family Gymnophthalmidae are poorly known. The author performed a phylogenetic analysis of species of three genera (Cercosaura, Pantodactylus, and Prionodactylus) currently included in the tribe Cercosaurini, subfamily Cercosaurinae. The analysis was based on 61 external morphological characters; maximum parsimony criterion was used. Polymorphic characters were analyzed with the generalized frequency method. The author proposed a classification consistent both with the recovered history and a previously published hypothesis based on molecular data. Pantodactylus and Prionodactylus were considered junior synonyms of Cercosaura, and the latter genus was redefined to include 11 species.
