This species occurs in the lake region of Chile, approximately from 40°S to 44°S, and from a single locality in Argentina (Puerto Blest, Río Negro Province). Its altitudinal range is from 50-1,000m asl.
Habitat and Ecology
This species is found under large logs and rocks near streams in temperate Nothofagus forest. Eggs are deposited in small, water-filled holes on hillsides.
It is uncommon even in suitable habitats. In Chile it was recorded as recently as November 2002, but there have been no records for Argentina since 1973.
The major threat to this species is habitat destruction caused by wood extraction and establishment of pine and eucalyptus plantations.
It occurs in Parque Nacional Tolhuaca and Parque Natural Alerce Costero in Chile. In Argentina, it occurs in Parque Nacional Nahuel Huapi. There is a need for improved legislation to protect remaining tracts of Nothofagus forest in the range of this species.
Red List Status
Near Threatened (NT)
Listed as Near Threatened because its Extent of Occurrence is probably not much greater than 20,000 km2, and its habitat is in decline, thus making the species close to qualifying for Vulnerable.
