Comment

In the Bufo debilis group of Martin, 1972, in Blair (ed.), Evol. Genus Bufo: 53. See comment under Anaxyrus punctatus. See accounts in Sanders and Smith, 1951, Field and Laboratory, 19: 141-160, and Bogert, 1962, Am. Mus. Novit., 2100: 1-37. The nominal subspecies (Anaxyrus debilis debilis and Anaxyrus debilis insidior) are unlikely to be more than arbitrarily defined sections of clines (DRF). Stebbins, 2003, Field Guide W. Rept. Amph., Ed. 3: 217, provided a brief account, figure, and map. Farr, Lazcano, and Lavín-Murcio, 2009, Herpetol. Rev., 40: 459-467, provided new records for Tamaulipas, Mexico, and commented on the range.
