This species is only known from two sites on the crest of the Serranía de los Paraguas on the border of the departments of Chocó and Valle del Cauca, in Colombia, between 2,100–2,250 m asl. Its extent of occurrence (EOO) is 17 km2.
Habitat and Ecology
The species is found in cloud forest, and individuals have been found perched on low vegetation inside dense undisturbed forests. It breeds by direct development.
It is a rare species. The last record for the species is from 1998, despite recent surveys in search for the species (W. Bolívar pers. comm. August 2016).
The species suffered a drastic population declines at the end of the 1990s, but there is no information if chytridiomycosis was the cause (G. González and B. Wilmar pers comm. August 2016). Localized threats include habitat loss due to agricultural activities, cattle grazing and logging.
Part of the range of the species is within Reserva Natural Cerro El Inglés.
In light of the possibility that chytrid may have been involved in declines, any surviving individuals might need to form the basis for the establishment of an ex-situ population.
Research in population trends, ecology, threats and distribution is recommended for the species.
Red List Status
Critically Endangered (CR)
Listed as Critically Endangered because it has not recuperated from the extreme decline probably caused by chytridiomycosis and has not been recorded since 1998 despite recent surveys. Population size is probably no more than 50 individuals.
