This species is found in Santuario de Fauna y Flora Guanentá Alto Río Fonce, Río Cañaverales, Santander Department, Colombia, at 1,700-2,000m asl.
Habitat and Ecology
It is an inhabitant of cloud forest, with breeding and larval development taking place in streams. It tolerates disturbed forest.
During the course of multiple visits undertaken in 1979-1982, this species was found to be common. There have been no subsequent surveys for the species, with the exception of one survey in 1992 when this species was not recorded, suggesting a serious decrease.
The most serious risk to this species is chytridiomycosis, which has had a devastating impact on other high-altitude species of Atelopus.
It occurs in the Santuario de Fauna y Flora Guanentá Alto Río Fonce. Further survey work is required to determine the biology and population status of this species. Given the threat of chytridiomycosis, successful conservation measures will probably need to include the maintenance of any surviving individuals in captivity.
