This species occurs in Parque Nacional Natural Los Picachos, Veredas la Esperanza and Andalucia, Caquetá Department, Colombia, between 1,750 and 2,500m asl. It might occur a little more widely.
Habitat and Ecology
It occurs and breeds in streams in premontane moist forest.
It is only known from four specimens collected between 1994 and 1998; there has been no subsequent survey work for the species.
The most serious risk to this species is chytridiomycosis, which has had a devastating impact on other high-altitude species of Atelopus. Habitat loss due to the planting of illegal crops is a threat to this species.
It occurs in Parque Nacional Natural Los Picachos. Survey work is required to determine the current population status of the species. Given the threat of chytridiomycosis, surviving individuals might need to form the basis for an ex-situ population.
