Range Description

Psychrophrynella saltator is only known from the type locality, ca 15 km (by road) from Charazani on the road to Apolo (2,550 m asl), Province of Saavedra, Department of La Paz, Bolivia (De la Riva 2007). It may occur in other nearby localities, although likely not far from the type locality (I. De la Riva pers. comm. 2008).

Habitat and Ecology

This species inhabits a region of semi-humid forest in the otherwise dry valley of the Río Charazani in the Cordillera de Apolobamba. Calling activity was recorded for the month of November, males call at night. Individuals have been found in a small patch of disturbed forest on both sides of the road. Males call while perched on plants 50 cm above the ground. These frogs are agile and able to jump (De la Riva 2007). This species is presumed to reproduce by direct development.


This is an abundant species at the type locality.

Population Trend


Major Threats

Agriculture, deforestation, habitat fragmentation and desertification have been observed at the type locality. In addition, a restricted geographic distribution and the predicted effects of climate change (e.g., drying up of regions) are considered to pose serious threats to the species (I. De la Riva pers. comm. 2008).

Conservation Actions

No conservation measures are known for this species.

Red List Status

Critically Endangered (CR)


Listed as Critically Endangered as it is only known from the type locality and the vicinity and is most likely restricted to this area. Its range is not within any protected area, and there is ongoing habitat loss occurring within it.

Taxonomic Notes

Psychrophrynella saltator is distinguished from other similar species by a combination of morphological characters, colour patterns, saltatorial behaviour and advertisement call features (De la Riva 2007).
