Telmatobufo australis is a species of frog in the family Calyptocephalellidae. It is endemic to Chile and occurs in the western and eastern slopes of the Chilean Coast Range in Valdivia and Osorno Provinces.[1] Its natural habitats are fast-flowing streams in temperate Nothofagus forest. It is a rare species threatened by habitat loss that is caused by siltation of streams caused by clear cutting and afforestation with exotic species.
