Incilius occidentalis (Camerano, 1879)

Type locality: Guanajuato, Mexico.

Holotype: Syntypes - MZUT (3 specimens).



The recognition of Incilius as a genus distinct from Bufo is highly controversial, and has not been accepted by many herpetologists working with this group. Pauly et al. (2004) discuss the phylogenetic relationships of species in this group, and retain the species within Bufo.
