Class: Amphibia > Order: Anura > Family: Telmatobiidae > Genus: Telmatobius > Species: Telmatobius timens

Synonym:

None

English names:

None

Diagnosis:

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.

snout; (3) snout rounded in dorsal view; (4) lips not flared; (5) postcommisural gland present; (6) tympanum not visible; a short supratympanic fold; (7) forelimb of males robust, without a humeral spine; (8) nuptial spicules moderately large, not too closely arranged; nuptial pad barely contacting inner palmar tubercle; (9) foot from 2/3 to fully webbed; plantar surface smooth; (10) tarsal fold poorly marked or absent; (11) dorsal skin with scattered flat pustules; (12) dorsum gray, with dark gray dots; (13) venter gray; ventral surfaces of limbs orange or yellow with

Type locality:

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

Distribution:

Bolivia, Peru

Ecology:

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.
