Geographic Occurrence

Natural Resident: Mexico

Endemic: Mexico


Confused with Incilius occidentalis prior to its naming according to the original publication, where comparative external morphology comprised the evidence; however the sampling density of nearby Incilius occidentalis was low and this has resulted in published concerns for the status of this taxon (see Castro-Bastidas, Velarde-Garcéz, Jacobo-González, and Serrano-Serrano, 2024, Sonoran Herpetol., 37: 43–44, for discussion of the discordant variation in the Sierra Surutato region of Sinaloa, Mexico, and possibility that more species in the complex may exist). See comment under Incilius occidentalis. Mendelson, Mulcahy, Williams, and Sites, 2011, Zootaxa, 3138: 1–34, suggested that Incilius mccoyi is a members in an unnamed monophyletic group (the name Incilius alvarius group is available-DRF) that includes Incilius alvarius, Incilius occidentalis, Incilius mccoyi, and Incilius tacanensisLemos-Espinal, 2007, Anf. Rept. Chihuahua Mexico: 39–40, provided an account (as Bufo occidentalis) for Chihuahua, Mexico. Streicher, Reyes-Velasco, Cox, Campbell, and Flores-Villela, 2014, Herpetol. Notes, 7: 207–210, reported a number of records from montane Durango, Mexico. Rorabaugh and Lemos-Espinal, 2016, Field Guide Amph. Rept. Sonora: 141–143, provided a detailed account of natural history, morphology, and conservation status in Sonora, Mexico and regarded all earlier records of Incilius occidentalis to be referrable to Incilius mccoyiLemos-Espinal, Smith, and Valdes-Lares, 2019, Amph. Rept. Durango: 54–55, provided a brief account for Durango, Mexico. Castro-Bastidas, 2022, Rev. Latinoam. Herpetol., 5: 15–19, provided a record from the municipality of Badiraguato, northeastern Sinaloa, Mexico, and a dot map of the species.
