From the IUCN Red List Species Account:


Range Description

This species is known only from the type locality and the immediate vicinity, from between Balsa Puerto and Moyobamba (San Martin), Peru. It occurs at 1,000-2,000m asl.

Habitat and Ecology

This is a terrestrial species of montane primary forests on the eastern slopes of the Andes. It is a stream-breeding species and not believed to be present in modified habitats.


There is no information on population status or abundance, although it was recorded as recently as 2004.

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; however, the chytrid pathogen has not yet been positively confirmed in this species.

Conservation Actions

This species is present in the Bosque de Protección Alto Mayo. Given the possible threat of chytridiomycosis, disease management and captive-breeding programmes might be required, as is further survey work to establish the population status of this species.
