Comment

Placed in the former Bufo guttatus group by Blair, 1972, Evol. Genus Bufo: 346. According to Savage, 1972, J. Herpetol., 6: 25, this species, together with Incilius fastidiosus and Incilius peripatetes, forms a group related to the lowland Incilius valliceps; subsequently referred to as the Bufo fastidiosus group by Savage, 2002, Amph. Rept. Costa Rica: 195–198, who provided an account. See photograph, map, description of geographic range and habitat, and conservation status (as Bufo holdridgei) in Stuart, Hoffmann, Chanson, Cox, Berridge, Ramani, and Young, 2008, Threatened Amph. World: 185. Abarca, Chaves, García-Rodríguez, and Vargas: 150–152, provided the first record in 25 years. Mendelson, Mulcahy, Williams, and Sites, 2011, Zootaxa, 3138: 1-34, suggested that this species is a member of a monophyletic Incilius coniferus group that includes Incilius coniferus, Incilius chompipe, Incilius epioticus, Incilius fastidiosus, Incilius guanacastes, Incilius holdridgei, Incilius karenlipsae, Incilius periglenes, and Incilius peripatetes. Köhler, 2011, Amph. Cent. Am.: 104–115, compared this species to others in Central America and provided a range map and photograph.
