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