Big Bend Slider
Trachemys gaigeae (Hartweg, 1939)

Current SSAR Comments:
Forstner et al. (2014, Proceedings of the Sixth Symposium on the Natural Resources of the Chihuahuan Desert Region) and Parham et al. (2015, Proceedings of the California Academy of Science 62: 359–367) elevated T. g. hartwegi (extralimital) to species status based on genetic differences between it and T. g. gaigeae. Parham et al. (2015, op. cit.) also demonstrated the close relatedness of T. hartwegi to T. taylori and T. venustus. Rhodin et al. (2021, Chelonian Research Monographs (8): 1–472) accepted this arrangement.
