This species is known only from the type locality: Isla Mocha (38° 22'S; 73° 54'W), 40km from the coast of Chile near Concepción. Its altitudinal range is from 20-250m asl.
Habitat and Ecology
It can be found under logs in mixed temperate forest. It lays its eggs in small, terrestrial, water-filled holes on hillsides. The larvae develop in the same places.
The population of this species is very small. The most recent records are of three individuals collected in August 2001.
This species is threatened by habitat destruction caused by subsistence wood collecting and cattle ranching.
The island where this species occurs is currently protected by the Isla Mocha Reserve, although people live within this reserve; improved management of the existing protected area is required, as is close monitoring of the surviving populations.
Red List Status
Critically Endangered (CR)
