From the IUCN Red List Species Account:


Range Description

This species ranges from Ecuador (Parque Nacional Llanganates in Tungurahua Province), north to southern Valle del Cauca Department on the eastern and western flanks of the Cordillera Central in Colombia, between 2,800 and 4,700m asl. It might occur a little more widely.

Habitat and Ecology

It lives on fallen leaves and on the ground in montane forest, bush land and páramo. Some populations live in terrestrial bromeliads, leaf-litter, and on vegetation up to 50cm above the ground. Other populations are fossorial. It breeds by direct development and has only been found in undisturbed habitats.


It is rare, localized, and uncommon where found.

Population Trend


Major Threats

The major threats are deforestation, due to agricultural development, cultivation of illegal crops, fire, logging, and human settlement, and pollution resulting from the spraying of illegal crops.

Conservation Actions

It occurs in several protected areas.

Taxonomic Notes

Although this appears to be a relatively widespread species, it apears to be composed of multiple species with restricted distributions, with considerable variation in ecological requirements (T. Grant and D. Cisneros-Heredia pers. comm.).
