Remarks:
Many authors recognize atra as a separate species (e.g., Webb 1973; Flores-Villela 1993, Vetter 2004; Bonin, Devaux & Dupre 2006; Legler & Vogt 2013),
although others retain it as a subspecies of spinifera (e.g., McCord & Joseph-Ouni 2005a; Fritz & Havas 2006; Lemos-Espinal & Smith 2007b;
Cerdá-Ardura, Soberón-Mobarak, McGaugh & Vogt 2008).
Vetter (2004) noted that the correct spelling of the specific epithet is atra rather than ater, due to the feminine grammatical gender of Apalone.
Distribution:
Mexico
(Coahuila).
