Telmatobius timens (De la Riva, Aparicio & Ríos, 2005)
Class: Amphibia > Order: Anura > Family: Telmatobiidae > Genus: Telmatobius > Species: Telmatobius timens
Listed as Critically Endangered because of a drastic population decline, estimated to be around 80% (impacting four of the five threat-defined locations) and taking place 7-12 years ago, inferred from the apparent disappearance of most of the Acjanaco subpopulation and declines in Qurqurpampa, Nuevo Oriente and Lorohuachana subpopulations in Peru.

This species is known from the following geographical localities between 3,350-3,750 m asl: Valle de Tojoloque, Franz Tamayo Province, La Paz department, western Bolivia (De la Riva et al. 2005); at least four streams on the north slope of Abra Acjanaco pass, 27 km north-north-east (by road) of Paucartambo, in Cusco (A. Catenazzi pers. comm. February 2014); Manu National Park’s Qurqurpampa station, Cusco; and Lorohuachana, Santuario Nacional Megantoni, province of La Convención, also in Cusco, southeast Peru
It is known from humid puna, elfin forest and scrubland edges (A. Catenazzi pers. comm. January 2011), and has also been reported from Polylepis forests [R. Gutiérrez pers. comm. on iNaturalist observation http://www.inaturalist.org/observations/219132 (Accessed: September 9, 2013)]. At Acjanaco it also occurs in the upper limits of cloud forest. Individuals have been found at night in a small pool, 50 cm deep, on rocks in a stream, and in puna on rocks, in crevices, on the ground, and in moss adjacent to streams. Reproduction is by larval development in streams.
