From the IUCN Red List Species Account:


Range Description

This species is known from six localities, on the eastern flanks of the Andes in Morona-Santiago Province, Ecuador, at 2,000-3,450m asl.

Habitat and Ecology

This species is an inhabitant of sub-páramo and páramo. There is no specific information available on breeding, but it is likely to be similar to other Atelopus species, with breeding and larval development taking place in streams.


The population status of this species is not known, but sampling effort through its range is insufficient. It was last recorded in September 1985.

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. Habitat loss and degradation as a result of mining and logging is a major threat.

Conservation Actions

The range of this species slightly overlaps with Parque Nacional Podocarpus, although it has, to date, not been recorded from inside the park. Further survey work is required to determine the abundance of this species. In view of the severe risk of chytridiomycosis, ex-situ populations might need to be established.

Red List Status

Critically Endangered (CR)


Listed as Critically Endangered because of a projected population decline, estimated to be more than 80% over the next ten years, inferred from declines in other high altitude Atelopus species in the same region, probably due to chytridiomycosis.
