This species is known from three localities at 3,450-3,750m asl: Valle de Tojoloque, Franz Tamayo Province, La Paz Departament, western Bolivia; and two localities close to one another on the north slope of Abra Acanacú pass, 27km north-north-east (by road) of Paucartambo, in Cusco Departament, south-east Peru. The Bolivian and Peruvian localities are some 300km apart.
Habitat and Ecology
This species is known from humid páramo, but it is also suspected to occur in the upper limits of cloud forest. Individuals were found at night in a small pool, 50cm deep, and on rocks in a river, and in páramo on rocks, in crevices, on the ground, and in moss adjacent to streams. Reproduction is presumed to be by larval development in the streams.

Chytridiomycosis has devastated Telmatobius populations in Ecuador, and has been detected in T. marmoratus near Cusco in Peru (Seimon et al. 2005). Chytridiomycosis is therefore considered a very severe threat to this species, to the extent that such concerns have directed the etymology of its specific name, which means 'frightened', 'scared', or 'alarmed'.
This species is known from the Área Natural de Manejo Integrado Nacional Apolobamba in Bolivia.
