Range Description

This species is currently known only from Farellones (33° 32'S; 70° 19'W), in central Chile, 35km north-east of Santiago, at 2,300-3,000m asl. The exact location of the type locality is uncertain, though it is somewhere on the western slopes of the Andes in central Chile.

Habitat and Ecology

This stream-breeding species has been found under stones, close to mountain streams, where the surrounding vegetation comprises grasses and shrubs of cold Andean areas. It has free-swimming tadpoles.


The current known population comprises only a few adults. It was last collected in 2003, and the population is known to have declined substantially in recent years. Areas in which the species has been known to reproduce were found to have been completely destroyed in February 2002.

Population Trend


Major Threats

Currently, the primary threat to this species is from recreational skiing and tourist infrastructure development, since the only known locality where the species is found is in a ski resort.

Conservation Actions

Protection and maintenance of its existing habitat is a priority for this species, since it is not currently known from any protected area.
