|Taxonomic Notes:||There are tadpoles further north that could be Telmatobufo bullocki or Telmatobufo ignotus (C. Castro, F. Rabanal, J.C. Ortiz, A. Charrier pers. comm. July 2015). These samples are not included in this assessment until such time as their identities can be verified.|

Listed as Endangered because its extent of occurrence (EOO) is 3,054 km2, its population is considered to be severely fragmented, and there is a continuing decline in the extent and quality of its habitat in Arauco Province, Chile.
|Previously published Red List assessments:|
|Range Description:||This species is known from nine sites in the Coastal Range, Nahuelbuta, Arauco Province, Bio Bio and Araucania regions, Chile (Rabanal and Moreno 2014). It has an altitudinal range of 133–1,200 m Asl. Its EOO is 3,054 km2 and it is not expected to occur much more widely (C. Soto-Azat pers. comm. July 2015).|
Native:Chile (Biobío, La Araucania)

|Population:||It is thought to be uncommon and of relatively low abundance (J.C. Ortiz, C. Soto-Azat and H. Díaz-Paez pers. comm. July 2015). It is considered to be severely fragmented and the population is suspected to be decreasing due to declines in the extent and quality of habitat.|
|Current Population Trend:||Decreasing|
|Habitat and Ecology:||This species occurs in fast-flowing streams in temperate Nothofagus forest. It is tolerant of moderate habitat destruction. The tadpoles are free-swimming and feed by scraping algae off of submerged rocks.|
|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 major threat to the species is clear cutting and afforestation with pine plantations, which causes siltation of streams (which, in turn, makes it harder for the larvae to feed). It is also threatened by introduced salmonids (V. Moreno pers. comm. July 2015).|
This species does not occur in the Parque Nacional Nahuelbuta, but it does occur in private protected areas.
There is a need for additional protection and maintenance of habitat at sites at which this species is known to occur.
Further survey are required to determine the full distribution of this species.
