From the IUCN Red List Species Account:


Range Description

This species occurs in the rainforests of the Pacific slope of the Cordillera de Talamanca of south-western Costa Rica, between 1,480-1,820m asl.

Habitat and Ecology

This species occurs in stream margins in the upper portions of premontane wet forest and rainforest and in the lower section of lower montane rainforest. One female was collected in a bromeliad. This species' breeding site is unknown.


It was collected on a number of occasions in the 1970s. It has not been seen since the 1980s, but there have been no searches for it in known sites for at least 10 years, or perhaps more. Ther have been no recent sightings of the species as of August, 2007.

Population Trend


Major Threats

Forest destruction and possibly also airborne pollution are its major threats.

Conservation Actions

It should be noted that some other species of Craugastor that are associated with streams have undergone dramatic declines and disappearances at higher altitudes, possibly due to chytridiomycosis, and so this might be a threat to this species, and is something that needs to be monitored for carefully.

Red List Status

Data Deficient (DD)


Listed as Data Deficient in view of the absence of recent information on its extent of occurrence, status and ecological requirements.

Taxonomic Notes

This species was previously within the genus Eleutherodactylus (Crawford and Smith 2005). Further taxonomic studies are needed to confirm the validity of this species (Federico Bolaños pers. comm.)
