|
Rhinoclemmys Allozyme variation among six taxa of batagurine turtles, genus Rhinoclemmys, was assessed by horizontal starch-gel electrophoresis. Relationships were assessed both phenetically and cladistically, and the results were generally concordant. Rhinoclemmys funerea, R. areolata, and R. punctularia appear to form a closely related assemblage and are best considered as an unresolved trichotomy. Rhinoclemmys rubida forms a distinct subcluster to the funerea-areolata-punctularia group and is distinguished by a number of autapomorphic alleles. Two subspecies of R. pulcherrima, R. p. manni and R. p. incisa, form a separate cluster from the other species and are cladistically united by four synapomorphies. The accumulation of several autapomorphies in R. p. incisa and the concomitant high level of genetic variability forms a major discontinuity with the geographically adjacent R. p. manni, suggesting little or no effective gene flow between these taxa.
