From the IUCN Red List Species Account:

 

Range Description

This species occurs in the austral temperate forest of Chile (where it is known from several localities in the 11th Division) and Argentina between latitudes of 41°S and 46° 2'S. It is probably more widely distributed than currently understood. It has an altitudinal range of sea level to 1,400m asl (in Argentina).

Habitat and Ecology

This species’ habitat is the cold mountain streams of austral temperate Nothofagus forest, where it may tolerate some habitat disturbance. Specimens have been found under logs at the margin of mountain streams. Chilean localities typically occur in N. antartica, N. betuloides, and Drymis winteri forest, while at the Argentinian localities the main vegetation is pure deciduous N. pumilio forest. Reproduction takes place by larval development in streams.

Population

Very little data are available on its population status. A population of at least 20 individuals was found in 2002 in Caleta Level, Chile, and there appears to have been little change to the available habitat between 1990 and 2002.

Population Trend

Unknown

Major Threats

The major threat to this species is presumed to be introduced predatory salmonid fishes.

Conservation Actions

Some populations of this species occur in the national parks of Argentina (Parque Nacional Nahuel Huapi and Parque Nacional Los Alerces), and it is also present in several protected areas in Chile.
