This species is known only from the Cordillera de Nahuelbuta, Estero Cabrería, Provincia de Malleco, Chile (37° 50'S; 73° 00' W). It has an altitudinal range of 1,000-1,500m asl.
Habitat and Ecology
It occurs under logs or stones close to mountain streams, and the surrounding vegetation mainly comprises Nothofagus dombeyi and Araucaria araucana. Breeding takes place in streams.
The species is relatively abundant at the type locality. During breeding periods, it is possible to find large numbers of tadpoles in streams.
The main threat is the afforestation of the watershed where this species occurs with an introduced pine. When the pine is harvested, the effect on the surrounding breeding streams could be catastrophic.
It occurs in Parque Nacional Nahuelbuta.
