From the IUCN Red List Species Account:


Range Description

This Peruvian endemic is known from Abra Accanacu, Paucartambo, in the department of Cusco. The original publication gives an incorrect locality of "near Juliaca, Departamento: Puno". Records from Bolivia are misidentifications. It is present at elevations of 2,800-3,500 m asl.

Habitat and Ecology

It can be found in the altiplano shrublands, and may be found at the edges of agricultural land (but not in cultivated areas). It breeds by direct development.


It is common where it occurs.

Population Trend


Major Threats

General habitat loss through agricultural activity (cultivation of potatoes) and other human activities is the major threat.

Conservation Actions

It is probably present in Parque Nacional Manu, but populations occurring outside the park remain in need of protection.

Taxonomic Notes

Populations previously assessed as Noblella peruviana in fact pertain to Psychrophrynella usurpator.
