From the IUCN Red List Species Account:


Range Description

This species is known only from the Cordillera Cutucú, in Morona-Santiago Province, in southern Ecuador, around 1,975m asl.

Habitat and Ecology

This species is an inhabitant of humid montane forest. There is no specific information on their breeding habits, but these are likely to be similar to other Atelopus species, with breeding and larval development taking place in streams.


Although sampling effort through the species' range is insufficient, it is likely that this species has undergone a population decline (as seen in other montane species of Atelopus). It was last recorded in 1984, and is perhaps no longer present at the type locality.

Population Trend


Major Threats

The most serious risk to this species is chytridiomycosis, which has had a devastating impact on other high-altitude Atelopus species. Agriculture, both crops and livestock, as well as logging and infrastructure development for human settlement are major threats to the species’ habitat.

Conservation Actions

It is not known to occur in any protected areas. Surveys to confirm the continued existence of this species are needed; given the threat of chytridiomycosis, surviving individuals should be maintained in captivity.
