From the IUCN Red List Species Account:


Range Description

This species is known from the central part of the Venezuelan coastal mountain range on the Cordillera de la Costa, at elevations between 720 and 1,000m asl.

Habitat and Ecology

It occurs along streams in seasonal (semi-caducifolious) forests. It lays its eggs on leaves overhanging streams, and when hatched the larvae fall into the stream below where they develop further.


The population of this species is in decline, even in pristine habitats. It is associated with Atelopus cruciger, which has disappeared from almost all of its range, probably because of chytridiomycosis.

Population Trend


Major Threats

Agriculture, logging, water pollution, and infrastructure development for human settlement are all major threats to the species’ habitat. However, it is declining even in pristine habitats, suggesting that chytridiomycosis, or some other disease, may be playing a role in the observed declines.

Conservation Actions

Its range includes Parque Nacional El Avila and Parque Nacional Macarao. Further research is required to determine the reasons for its decline in pristine habitat. If disease is shown to be a major threat, then surviving individuals may need to form the basis for the establishment of an ex-situ population.

Red List Status

Endangered (EN)


Listed as Endangered because its Extent of Occurrence is less than 5,000 km2, all individuals are in fewer than five locations, and there is continuing decline in the extent and quality of its habitat on the Venezuelan coastal range.
