|Facilitator/Compiler(s):||Angulo, A., Hobin, L., Best, S.|
Listed as Least Concern in view of its wide distribution and presumed large population.
|Previously published Red List assessments:|
|Range Description:||This species was previously known from the western and eastern slopes of the Coastal Range in Valdivia and Osorno Provinces, Chile, between 0–1,000 m Asl. It is now also known from the western slopes of the Andean Cordillera (C. Cuevas pers. comm. July 2015) and may occur slightly more widely (F. Rabanal pers. comm. July 2015). The extent of occurrence (EOO) used to be 16,044 km2, but following the range extension it is now 28,007 km2.|

|Population:||It is known from only a few small, disjunct subpopulations, and is not often recorded (it was recorded as recently as 2013, A. Valenzuela pers. comm. July 2015). C. Cuevas found 15 individuals in half an hour during surveys in October 2002 (the breeding period) and it remains a rare species (C. Cuevas pers. comm. July 2015). It is not considered to be severely fragmented, but due to ongoing declines in the extent and quality of habitat the population is suspected to be decreasing.|
|Current Population Trend:||Decreasing|
|Habitat and Ecology:||This species occurs in fast-flowing streams in temperate Nothofagus forest. The tadpoles are free-swimming and feed by scraping algae off of submerged rocks. It is tolerant of minor habitat destruction.|
|Continuing decline in area, extent and/or quality of habitat:||Yes|
|Movement patterns:||Not a Migrant|
|Use and Trade:||There are no records of this species being utilized.|
|Major Threat(s):||The main threat to this species is the siltation of streams, which makes it difficult for larvae to feed and is caused by clear cutting and afforestation with exotic species. Cattle grazing is also a threat to this species (C. Cuevas pers. comm. July 2015), as are invasive wild pigs (A. Valenzuela pers. comm. July 2015).|
It is not known to occur in any protected areas, although it does occur in private protected areas, including from the Universidad Austral de Chile (C. Cuevas pers. comm. July 2015).
Additional protection of native forests is needed.
Information on basic population status and distribution is needed.
