This species occurs along the western slope of the Peruvian Andes in the Regions of Ancash and Lima. Additional records were identified in 2014 by S. Rios just over the border from Lima Region into Ica Region (D. Rodriguez pers. comm. April 2017). Its elevational range is 2,000–4,000 m asl and its EOO is estimated to be approximately 17,561 km2.
Habitat and Ecology
It is a semi-aquatic frog found in streams, canals and ditches within riparian areas. It breeds by larval development. Tadpoles have been found active during the day in streams with underwater vegetation (Aguilar et al. 2007).
It is abundant where it occurs, however the population is suspected to be decreasing due to ongoing decline in the quality and extent of its habitat.
The major threats to this species are water pollution through agrochemicals and domestic waste. It might be utilized locally for food, but this requires confirmation. Telmatobius populations living at high elevations might be particular prone to becoming infected with chytridiomycosis; the pathogen has yet to be reported from this species.
It occurs in Nor Yauyos-Cochas Landscape Reserve.
Habitat protection is recommended throughout other areas of the species' range, complemented by more general actions to mitigate the effects of habitat loss from water pollution.
More information is needed on this species' distribution, population status, natural history, and threats, including whether this species is utilized or infected with chytrid.
Red List Status
Listed as Vulnerable, as this species has an extent of occurrence (EOO) of 17,561 km2, it occurs in one to nine threat-defined locations, and there is a continuing decline in the quality of its habitat along the western slope of the Peruvian Andes.
