Comment

In the former Bufo valliceps group of Martin, 1972, in Blair (ed.), Evol. Genus Bufo: 49. See accounts by Porter, 1964 "1963", Herpetologica, 19: 229-247, Mendelson, 1997, Herpetologica, 53: 279-281, and Mendelson, 1998, Cat. Am. Amph. Rept., 645: 1-2, who corrected many misidentifications imbedded in the literature. Korky and Webb, 1973, J. Herpetol., 7: 47-49, reported on larval morphology. See map, description of geographic range and habitat, and conservation status (as Bufo cavifrons) in Stuart, Hoffmann, Chanson, Cox, Berridge, Ramani, and Young, 2008, Threatened Amph. World: 181. Mendelson, Mulcahy, Williams, and Sites, 2011, Zootaxa, 3138: 1-34, suggested that this species is a member of a monophyletic Incilius valliceps group and in a subgroup they referred to as the Forest Group (the name Incilius cristatus subgroup is available—DRF) that includes Incilius aucoinae, Incilius cavifrons, Incilius campbelli, Incilius cristatus, Incilius leucomoyos, Incilius macrocristatus, Incilius melanochlorus, Incilius spiculatus, and Incilius tutelarius. Oliver-López, Woolrich-Piña, and Lemos-Espinal, 2009, Fam. Bufonidae Mex.: 64–66, provided an account (as Ollotis cavifrons).
