Beschreibung:
<p>Taxonomic history of emydine turtles in the Chrysemys-Pseudemys-Trachemys complex is reviewed. The extensive controversy on generic assignment of these turtles (Chrysemys sensu stricto or sensu lato) has resulted from different morphological, biochemical and paleontological interpretations. Nevertheless, most evidence suggests a broad trichotomy among painted turtles (C. picta), sliders (scripta series), and cooters (floridana, concinna and rubriventris series). These groups appear to be as divergent from each other as they are from the genus Graptemys. We propose that recognition of Chrysemys, Trachemys, and Pseudemys as distinct genera is the most natural, utilitarian, and conservative arrangement. Generic accounts including synonymies and descriptions are presented.</p>
