From the IUCN Red List Species Account:


Range Description

This species occurs on the Amazonian slopes of the Cordillera Oriental in Colombia (to 5° 30'N) south to the Cordillera Central; along the length of the eastern slopes of the Andes in Ecuador and in Cusco, Junín, San Martín, Pasco, and Ucayali departments in Peru; at elevations of 410-2,190m asl.

Habitat and Ecology

It is an arboreal and aquatic frog found in or along streams in cloud montane forest. Individuals have been seen on low bushes over torrential mountain streams, others have been found on vegetation along streams at night and in bromeliads by day (Duellman, 1972). It is not found in secondary forest, and it presumably breeds in streams.


In Podocarpus in 1998, it was uncommon. It is common in Colombia, and in 2002, it was common in San Martin, Peru.

Population Trend


Major Threats

The principal threat to the species is the deforestation around streams for coffee and coca plantations.

Conservation Actions

It is present in some Protected Natural Areas in Peru and in Yanachagana Chemillén, Manu, and Tingo María National Parks. In Ecuador, its geographic range overlaps with Parque Nacional Sumaco Napo-Galeras, Parque Nacional Llanganates, Parque Nacional Podocarpus and Parque Nacional Sangay. In Colombia, it occurs in several protected areas.

Taxonomic Notes

This species was previously within the genus Hyla but has recently been moved to the resurrected genus Hyloscirtus (Faivovich, et al., 2005).
