This species is mostly found in the temperate Nothofagus forests of Chile (40° 50'S to 45° 20'S), with a single known locality in Argentina (Lago Puelo National Park, Chubut Province) (Ubeda et al., 1999). Its altitudinal range is from 0-1,500m asl.
Habitat and Ecology
It is a terrestrial species of humid forests associated with cold streams. Larval development takes place in water-filled cavities on the ground. Adults occur under logs or in small holes at the edges of forest streams. Males call in the breeding season from small holes during the daytime. Females deposit eggs inside the holes and free-swimming tadpoles characterize the species. It is not recorded from degraded habitats.
Populations are generally small. During the breeding season, up to 15 individuals can aggregate. It was last recorded during November 2002.
Destruction and degradation of native Nothofagus forests (generally through fires and plantation forestry with exotic species) are major threats.
The species is present in at least six national parks in Chile and one in Argentina. Legislation to protect the native Nothofagus forest habitat is needed.
