From the IUCN Red List Species Account:


Range Description

This species is known only from the type locality, the headwaters of the Río Piuntza, in the Cordillera del Condór, Morona Santiago Province, south-eastern Ecuador, at an altitude of 1,830m asl, although it probably occurs more widely.

Habitat and Ecology

It lives in cool montane cloud forest (Duellman and Simmons 1988). Its reproductive mode is unknown, but the larvae probably develop in streams. It occurs sympatrically with Colostethus exasperatus and C. shuar.


There is no information on the population status of this species, which is known only from the type series collected in early 1972 (when it was fairly common, with 18 specimens being collected).

Population Trend


Major Threats

There is no information on threats to this species, although it is known that in 1996 there was forest still remaining at the type locality.

Conservation Actions

It is not known to occur in any protected areas, although the Cordillera del Condór is under little threat because the land mines left during the 1995 border war mean that there is little human disturbance of the region.
