Geographic Range [top]

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).
Countries:	Native: Argentina; Chile

Population [top]

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

Habitat and Ecology [top]

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.
Systems:	Terrestrial; Freshwater
