dc.description.abstract"More than 100 females and yet no males of Kentropyx borckiana are known from northern South America and Barbados. Features of external morphology, karyotypes, and biochemical genetics (electrophoresis of proteins encoded by 45 presumptive gene loci) reveal that individuals of K. borckiana from Guyana represent a unisexual clone that originated from one or more parthenogenetic F1 hybrids between Kentropyx calcarata X Kentropyx striata, the other two species of this genus known previously from the Guiana Region. Comparisons include data for Kentropyx altamazonica also, including the first specimens known from Venezuela (Amazonas Territory). Although K. altamazonica and K. calcarata are morphologically similar, genetically they are quite distinct. Origin of the unisexual Kentropyx borckiana involved hybridization between both morphologically and ecologically distinct ancestral species, unlike several other unisexual lizards of Neotropica. For example, clones of the parthenogenetic Gymnophthalmus underwoodi, Cnemidophorus cryptus, and Cnemidophorus pseudolemniscatus originated in the Guiana Region from hybrids between morphologically and ecologically similar, yet genetically distinct, ancestral species"--P. 2.en_US
