Geographic Occurrence

Natural Resident: Mexico

Endemic: Mexico


In the former Bufo marmoreus group of Martin, 1972, in Blair (ed.), Evol. Genus Bufo: 51. See account by McDiarmid and Hardy, 1969, Univ. Kansas Publ. Mus. Nat. Hist., 18: 81–82. Mendelson, Mulcahy, Williams, and Sites, 2011, Zootaxa, 3138: 1–34, suggested that Incilius canaliferus is a members in an unnamed monophyletic group (the name Incilius marmoreus group is availabe-DRF) that includes Incilius canaliferus, Incilius marmoreus, and Incilius perplexusOliver-López, Woolrich-Piña, and Lemos-Espinal, 2009, Fam. Bufonidae Mex.: 78–80, provided an account for Mexico (as Ollotis marmorea). Köhler, 2011, Amph. Cent. Am.: 104–115, compared this species to others in Central America and provided a range map and photograph. Lemos-Espinal and Smith, 2015, Check List, 11(1642): 1–11, noted the occurrence of the species in Hidalgo, Mexico, although with no definite locality. Rorabaugh and Lemos-Espinal, 2016, Field Guide Amph. Rept. Sonora: 136–138, provided a detailed account of natural history, morphology, and conservation status in Sonora, Mexico. Lemos-Espinal and Dixon, 2016, Amph. Rept. Hidalgo: 354–355, provided a brief account and map for Hidalgo, Mexico. Lemos-Espinal, Smith, and Valdes-Lares, 2019, Amph. Rept. Durango: 52–53, provided a brief account for Durango, Mexico, although the single record is doubtful on geographic grounds (DRF). Loc-Barragán, Smith, Woolrich-Piña, and Lemos-Espinal, 2024, Herpetozoa, Wien, 37: 30, reported on the distributional and conservation status in the state of Nayarit, Mexico.
