Arizona Mud Turtle
Kinosternon stejnegeri (Hartweg, 1938)
kee-noe-STER-non — sty-ne-JER-ai

SSAR 9th Edition Comments:
McCord (2016, Historical Biology 28: 310–315) recommended restricting Kinosternon arizonense to fossil material and resurrecting the name K. stejnegeri for extant populations. Joyce and Bourque (2016, Bulletin of the Peabody Museum of Natural History 57: 57–95) accepted this arrangement. Turtle Taxonomy Working Group (2021, Chelonian Research Monographs (8): 1–472) list K. stejnegeri as the extant species, with K. arizonense considered a separate extinct species from the Pliocene-Pleistocene.
