This species is known only from the region of the type locality: El Tambo, near Guisito, at 800m asl, Cauca Department, Colombia. Lötters (1996) suggested that the elevation given for the type locality (300m asl) was a typographic error in the original publication.
Habitat and Ecology
It lives on the ground in tropical humid forests, and presumably breeds in streams.
There is no recent information on the population status of this species.
The major threat is likely to be chytridiomycosis, as has occurred in many other species of Atelopus (although its occurrence at lower altitudes might afford it some level of protection from the disease). Additional threats include deforestation for agricultural development, illegal crops, logging and human settlement, and pollution resulting from the spraying of illegal crops.
It occurs in Parque Nacional Natural Munchique. In view of the severe risk of chytridiomycosis, it is a high priority to conduct surveys to determine the current population status of this species, as well as to initiate a captive-breeding programme
