This species is known only from the western slopes of the Chilean Andes at San Ignacio de Pemehue, Cautin Province in Chile at 1,000 m asl. Its extent of occurrence (EOO) is 171 km2.
Habitat and Ecology
The habitat for this species is unknown, as is the breeding ecology although it could be presumed to breed by larval development in streams similar to other species in the genus.
This species has not been seen since its description at the beginning of the 20th century and three recent expeditions in 1995, 1996, and 2002 all failed to locate it. The population trend is unknown.
Habitat destruction caused by pine plantations might be a threat to this species, although this requires verification of habitat preference.
It is not known to occur in any protected areas.
Research on the taxonomy status, population and distribution, ecology and threats for this species is required.
Red List Status
Data Deficient (DD)
Listed as Data Deficient as it is known only from the original collection made over 100 years ago and there is lack of information on its distribution, population status, ecology and threats.
