Comment

In the former Bufo marmoreus group of Martin, 1972, in Blair (ed.), Evol. Genus Bufo: 50. See map, description of geographic range and habitat, and conservation status (as Bufo perplexus) in Stuart, Hoffmann, Chanson, Cox, Berridge, Ramani, and Young, 2008, Threatened Amph. World: 190. Mendelson, Mulcahy, Williams, and Sites, 2011, Zootaxa, 3138: 1-34, suggested that Incilius canaliferus is a members in an a monophyletic group referred to as the Pacific Versant group (the name Incilius marmoreus group is available—DRF) that includes Incilius canaliferus, Incilius marmoreus, and Incilius perplexusOliver-López, Woolrich-Piña, and Lemos-Espinal, 2009, Fam. Bufonidae Mex.: 88–89, provided an account for Mexico (as Ollotis perplexa) although the range map is substantially out of date.
