From the IUCN Red List Species Account:


Range Description

This species occurs on the Amazonian slopes of the Andes, in Napo Province, Ecuador, from 1,660-1,910m asl. Records from Colombia and Venezuela are in error (Ruiz-Carranza et al. 1996). In Ecuador, the sampling effort throughout the distribution range might be insufficient, and the known number of localities and its extent of occurrence are likely to increase with more sampling.

Habitat and Ecology

It occurs along streams in cloud forest where the annual mean precipitation is 2,000-4,000mm and annual mean temperature is 18-24°C (Coloma 1995). Its level of tolerance to habitat disturbance is unclear, although it may tolerate some selective logging. Its reproductive mode is unknown, but the larvae are likely to develop in streams.


There are no data available on the population status of this species, and there have been no recent records.

Population Trend


Major Threats

The main threat to this species is probably deforestation due to expansion of agriculture. It is also threatened by atmospheric and water pollution, and by invasive alien species.

Conservation Actions

In Ecuador, its range overlaps with Parque Nacional Sumaco Napo-Galeras, and possibly with the Reserva Ecológica Cayambe-Coca.

Red List Status

Data Deficient (DD)


Listed as Data Deficient in view of continuing uncertainties as to its extent of occurrence, status and ecological requirements.

Taxonomic Notes

This form probably contains a number of undescribed species, according to Rivero (1991).
