This species is known only from the vicinity of the type locality of Cordillera Carabaya on the Amazonian versant of Departamento Puno, Peru. Records of this species from Departamento Huánuco and Departamento Ucayali (Rodriguez, Cordova and Icochea 1993) require further investigation. It has an altitudinal range of 1,800-2,500m asl.
Habitat and Ecology
This species' habitat is cloud forest on the Amazonian versant of the Peruvian Andes. The species is not expected to be tolerant of habitat degradation. Breeding is presumed to take place in streams.
Its population is unknown, but it might be declining. It has been recorded as recently as 2003.
The major threat is likely to be chytridiomycosis, leading to a catastrophic population decline, as has occurred in many other montane species of Atelopus. This disease has not yet been recorded in this species, but incidence of the disease is known to be spreading in northern Peru.
This species is not present in any protected areas. If chytridiomycosis is indeed shown to be a threat to this species, then the maintenance of populations in captivity will be a needed conservation measure.
