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, and McDiarmid and Hardy, 1969, Univ. Kansas Publ. Mus. Nat. Hist., 18: 82-84. See comment under Incilius gemmifer. 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 Lowland group (the name Incilius valliceps subgroup is available—DRF) that includes Incilius gemmifer, Incilius luetkeni, Incilius mazatlanensis, Incilius nebulifer, and Incilius vallicepsLemos-Espinal, 2007, Anf. Rept. Chihuahua Mexico: 38, provided an account (as Bufo mazatlanensis) for Chihuahua, Mexico. Oliver-López, Woolrich-Piña, and Lemos-Espinal, 2009, Fam. Bufonidae Mex.: 80–82, provided an account for the state of Mexico (as Ollotis mazatlanensis), although the range map for the northern portion of the range is misleading. Valdes-Lares, Martín-Muñoz de Cote, and Muñiz-Martínez, 2013, Herpetol. Rev., 44: 646, provided new records for Durango, Mexico.
