This species is only known from its type locality of La Empalada, in the municipality of Mistrató, Risaralda Department, Colombia, between 1,760–1,790 m asl. There has been quite extensive sampling in the neighbouring regions suggesting that it is most likely confined to this area. Its EOO is 10 km2.
Habitat and Ecology
This species is usually found on low vegetation and in leaf-litter inside primary cloud forest. It has not been recorded outside forest habitat. It breeds by direct development.
It is a rare species. The last recorded specimen is from 1992. Recent surveys looking for the species have not found any individuals (G.González pers. comm. August 2016). Due to ongoing decline in the extent and quality of habitat, the population is suspected to be decreasing.
The major threat is habitat loss caused by agricultural development and cattle grazing.
The species has not been found within any protected area.
It is recommended to protect part of the distribution of the species.
Further surveys to look for the species is needed. Research in population trends, ecology and threats are also recommended for the species.
Red List Status
Critically Endangered (CR)
Listed as Critically Endangered given that it it is known only from the type locality, with an extent of occurrence (EOO) of 10 km2, that is subject to continuing decline in extent and quality of its habitat due to agricultural activities and cattle grazing. The species has not been recorded since 1992 despite recent surveys looking for the species.
This is the sister species of Pristimantis bellona according to Lynch and Ruíz-Carranza (1996b).
