Range Description

Psychrophrynella illampu is known from the type locality, 18.5 km from Sorata on Sorata-Mapiri road (15 44' 07" S, 68 38' 11" W, 3840 masl) and its surroundings, in the Province of Larecaja, Department of La Paz, Bolivia (De la Riva, 2007). The species may possibly be found within a few kilometres from the type locality (I. De la Riva, pers. comm. 2008).

Habitat and Ecology

The species can be found in the upper part of open elfin forest and the adjacent humid paramo. Individuals were located under stones near a small lake with dirty water. One clutch of eight brown, translucent eggs 5.5 mm in diameter was found under a stone in the month of November. The eggs contained much yolk, and the embryos had well-developed legs. Calling activity has been reported for the month of March, with males calling just before dusk but becoming silent shortly after. Gastrotheca marsupiata was common in the area in 1999 (De la Riva, 2007).


It is considered to be a common species in the type locality (De la Riva, 2007).

Population Trend


Major Threats

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

Vulnerable (VU)


Listed as Vulnerable in view of its extent of occurrence of less than 20,000 km2, area of occupancy of less than 2,000 km2, with all individuals in fewer than ten locations, and a projected decline in the extent and quality of its habitat due to climate change.

Taxonomic Notes

Psychrophrynella illampu is distinguished from other similar species by a combination of colour patterns and morphological features (De la Riva, 2007).
