From the IUCN Red List Species Account:   Range Description This species is endemic to Ancash Department, Peru. It is restricted to the Río Santa, from the type locality of the "mouth of Rio Santa 500m from Lake Conococha, Provincia Recuay (4,050m asl)" 30km northwards along this river and in small rivers and waterways associated with the river (Conococha, Catac, Laguna Aguashcocha, Pachacoto). It has an altitudinal range of 3,515-4,150m asl. Habitat and Ecology It is a riparian, semi-aquatic stream-breeding, frog restricted to the puna region, and may be found under rocks and submerged plants in slow-moving sections of rivers. It is not recorded from degraded habitats. Population It is uncommon. Population Trend Decreasing Major Threats Major threats include local use for food and medicine (including the larvae), and water pollution from mining and agrochemical use. Telmatobius populations living at high elevations are particularly prone to infection with chytridiomycosis, and, although the pathogen has yet to be reported from T. mayoloi it could be at risk. Conservation Actions It is present in Parque Nacional Huascaran. There is a need to regulate harvesting and offtake of this species. Close population monitoring is required, particularly given the potential threat of chytrid. Citation Javier Icochea, Edgar Lehr 2004. Telmatobius mayoloi. In: IUCN 2012   IUCN Terms of Use
