From the IUCN Red List Species Account:


Range Description

This species is known from Pichinca and Esmeraldas provinces, in the north-western versant of the Andes of Ecuador, between 700 and 2,200m asl. It is known from more than ten localities.

Habitat and Ecology

This species is an inhabitant of lowland rainforest and humid montane forest. Eggs are laid in strings in streams, and tadpoles attach themselves to rocks.


There is no current information on the population status of this species; it was last recorded in 1989, despite survey efforts, suggesting a serious population decrease.

Population Trend


Major Threats

The major threat is likely to be a catastrophic decline, due to chytridiomycosis, as has occurred in many other species of Atelopus. Agriculture, both crops and livestock, as well as logging, are also major threats to the species’ habitat, and very little suitable habitat remains.

Conservation Actions

The range of this species overlaps Reserva Ecológica Cotacachi-Cayapas and just reaches the northern limit of Reserva Ecológica Los Illinizas. Additional survey work is urgently needed to determine whether or not this species still persists. In view of the severe risk of chytridiomycosis, surviving individuals might need to form the basis for the establishment of an ex-situ population.

Red List Status

Critically Endangered (CR)


Listed as Critically Endangered because of a drastic population decline, estimated to be more than 80% over the last three generations, inferred from the apparent disappearance of most of the population, probably due to chytridiomycosis.
