Abstract
The turtle family Geoemydidae represents the largest, most diverse, and most poorly understood family of turtles. Little is known about this group, including intrafamilial systematics. The only complete phylogenetic hypothesis for this family positions geoemydids as paraphyletic with respect to tortoises, but this arrangement has not been accepted by many workers. We compiled a 79-taxon mitochondrial and nuclear DNA data set to reconstruct phylogenetic relationships for 65 species and subspecies representing all 23 genera of the Geoemydidae. Maximum parsimony (MP) and maximum-likelihood (ML) analyses and Bayesian analysis produced similar, well-resolved trees. Our analyses identified three main clades comprising the tortoises (Testudinidae), the old-world Geoemydidae, and the South American geoemydid genus Rhinoclemmys. Within Geoemydidae, many nodes were strongly supported, particularly based on Bayesian posterior probabilities of the combined three-gene dataset. We found that adding data for a subset of taxa improved resolution of some deeper nodes in the tree. Several strongly supported groupings within the Geoemydidae demonstrate nonmonophyly of some genera and possible interspecific hybrids, and we recommend several taxonomic revisions based on available evidence.
