From the IUCN Red List Species Account:


Range Description

This species is known from elevations of 1,710-2,620m asl in the southern part of the Cordillera Oriental, in the provinces of Loja and Zamora Chinchipe, 1,700m asl in the Cordillera de Cutucù, and from 1,550m asl on the western slopes of the Cordillera del Cóndor, Morona-Santiago Province. The only Peruvian record is from the upper Río Comainas, at 1,750m asl, on the eastern slopes of the Cordillera del Cóndor, in the province of Condorcanqui, Amazonas Department. Sampling effort through the range is insufficient.

Habitat and Ecology

This species can be found in montane cloud forests; specimens have been collected in bromeliads and in low vegetation by night (Lynch 1979c). In the Cordillera del Cóndor of Ecuador, gravid females were found in January and August. Breeding is thought to take place by direct development.


It is very rare in Ecuador, while in Peru only a single juvenile specimen has been recorded.

Population Trend


Major Threats

Conservation Actions

It occurs in the Santiago Comainas Reserve Zone, Peru, and in Parque Nacional Podocarpus in Ecuador. Further survey work is needed to better understand the limits of the distribution of this species.
