From the IUCN Red List Species Account:


Range Description

This species is known from the type locality, Serrania Las Baldias, and from one other locality, Belnira, Paramo Morron, both of which are in Antioquia Department, in Colombia, between 2,800 and 3,100m asl.

Habitat and Ecology

It occurs on vegetation along streams in natural forest edge in the high Andes, and has not been recorded from disturbed habitats. Breeding and larval development take place in streams.


It is not a common species, and recent surveys have not found any specimens at the type locality; a decline has also been observed at the other known locality. The most recent record of the species was apparently in 2000.

Population Trend


Major Threats

The major threat is likely to be chytridiomycosis, leading to a catastrophic population decline, as has occurred in many other montane species of Atelopus. Other major threats include habitat loss, due to agricultural expansion (illegal crops), water pollution from agriculture, and possibly climate change.

Conservation Actions

The range of the species is not within any protected areas. Further survey work is required to determine the population status of this species and the limits of its range. In view of the threat of chytridiomycosis, the status of this species should be closely monitored, and ex-situ populations should be established.
