Geographic Occurrence

Natural Resident: Costa Rica, Panama


Confused with Incilius melanochlorus prior to its description according to the original publication. See photograph, map, description of geographic range and habitat, and conservation status (as Bufo aucoinae) in Stuart, Hoffmann, Chanson, Cox, Berridge, Ramani, and Young, 2008, Threatened Amph. World: 179. Mendelson, Mulcahy, Williams, and Sites, 2011, Zootaxa, 3138: 1-34, suggested that this species is a member of a monophyletic Incilius valliceps group and in a subgroup they referred to as the Forest Group (the name Incilius cristatus subgroup is available—DRF) that includes Incilius aucoinae, Incilius cavifrons, Incilius campbelli, Incilius cristatus, Incilius leucomoyos, Incilius macrocristatus, Incilius melanochlorus, Incilius spiculatus, and Incilius tutelarius. Köhler, 2011, Amph. Cent. Am.: 104–115, compared this species to others in Central America and provided a range map and photograph.
