This species is known from the south-eastern Andes of Perú (Moquegua and Tacna departments), and a single site in Chile: Putre, Parinacota Province, close to the Peruvian border, at 3,300m asl.
Habitat and Ecology
It is a riparian, semi-aquatic frog, occurring in streams and small rivers in the high Andes. Breeding takes place in streams. It is not known to occur in modified or degraded habitats.
There is little recent information on the status of this species in Peru. The small Chilean population is declining, and was last seen in 1986; several visits to the site in 1996 and 2003 failed to turn up any records.
In Peru, there are some localized threats including habitat loss, through mining and agricultural activities, and small-scale harvesting for food and medicine. In Chile, it is locally threatened by human water consumption and water pollution, leading to the drying out of streams. Telmatobius species living at high elevations might be particularly prone to infection with chytrid, although this pathogen has yet to be reported from T. peruvianus.
It has not been recorded from any protected areas, and there is a need for improved habitat protection at sites at which the species has been recorded. In Chile, there is a need for further survey work to determine the species' current population status. There is a need for close monitoring of the status of this species given the potential threat of chytridiomycosis.
Red List Status
Listed as Vulnerable because its Extent of Occurrence is less than 20,000 km2, its distribution is severely fragmented, and there is continuing decline in the extent and quality of its habitat, and in the number of mature individuals, in the Chilean Andes.
