From the IUCN Red List Species Account:


Range Description

This species occurs in the mountains of the Cordillera Central and Talamanca in Costa Rica, at 1,930-2,800m asl. It might occur slightly more widely.

Habitat and Ecology

A nocturnal stream-breeding treefrog occurring in fast-flowing streams in lower montane and montane rainforests. Males call from rocks in streams and along stream margins, and sometimes from low vegetation near streams. Tadpoles typically are found adhering to large rocks in cold mountain streams (Savage 2002).


Recent searches in Cerro Chompipe, a known historical locality that has not suffered much habitat modification, have not found this species, although it continues to be seen at Cerro de la Muerte and several other localities within its range.

Population Trend


Major Threats

Major threats include habitat destruction, pollution, and climate change. The decline witnessed at Cerro Chompipe could be due to chytridiomycosis.

Conservation Actions

Much of the species' range is included within national parks, including Parque Internacional La Amistad. There is a need for close population monitoring of this species, given the potential threat of chytridiomycosis.

Red List Status

Endangered (EN)


Listed as Endangered because its Extent of Occurrence is less than 5,000 km2, its distribution is severely fragmented, there is a decline in the number of mature individuals, and there is continuing decline in the extent and quality of its habitat outside of protected areas.
