From the IUCN Red List Species Account:


Range Description

This species' geographic range is the Amazonian slopes of the Andes of Peru (Departamentos Cusco and Puno) and Bolivia (Departamentos La Paz, Cochabamba and Santa Cruz). Its altitudinal range of 1,000-2,500m asl.

Habitat and Ecology

The habitat is primary montane and cloud forests on the eastern slopes of the Andes. It breeds in fast-flowing streams (highly adapted to this) and is not present in modified habitats.


Locally, it is very common.

Population Trend


Major Threats

Deforestation through smallholder farming and mining (water pollution) are major threats. Chytrid fungus might be a threat to this species but requires confirmation.

Conservation Actions

In Peru this species might occur in Apurimac Reserved Zone, Parque Nacional Manu, Amarakaeri Reserved Zone; but this requires confirmation. Present in several Bolivian protected areas.

Red List Status

Least Concern (LC)


Listed as Least Concern in view of its wide distribution, presumed large population, and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category.

Taxonomic Notes

This species was previously within the genus Hyla but has recently been moved to the resurrected genus Hyloscirtus (Faivovich, et al., 2005). Severe taxonomic difficulties exist with this species. It is a complex with possibly more than three species involved (S. Reichle pers comm.).
