This species is known from two localities in the Cordillera Occidental of the Colombian Andes: the municipality of El Tambo in Cauca Department; and Alto del Oso in Choco Department. It has been recorded at 1,000-1,550m asl. It probably occurs in suitable areas in between the known localities.
Habitat and Ecology
This species occurs underground or among fallen leaves within montane forests. The eggs are presumably laid on land, with the hatching larvae falling into streams to complete their development.
There is no information on its population status, and it is known only from one specimen from each locality.
There is no information on specific threats to this species. Possible threats include loss of mountain forest for livestock rearing, agricultural activities and water pollution, but the significance of these depends on the ability of this species to adapt to changed habitats.
Neither of the two known localities is in a protected area. However, there are several national parks between the two localities, in which the species might occur.
Red List Status
Data Deficient (DD)
Listed as Data Deficient in view of continuing uncertainties as to its taxonomic status, extent of occurrence and ecological requirements.
The taxonomy of this species' genus is in need of revision (Wilkinson pers. comm.).
