This species is known only from the type locality of Cerro Madrid (29° 39'S; 68° 36'W), in Gualcamayo Valley at 3,050m asl in San Juan Province, Argentina. This is the southernmost species of Telmatobius.
Habitat and Ecology
All that is known about its habitat and ecological requirements is that it is thought to have been collected from a mountain stream.
It is known only from the type series of three individuals.
The type locality is in a gold mining area that is dangerous for researchers to visit, so the threats to this species remain poorly known. It is possible that the presumed aquatic habitat of this species might be being polluted by mercury, although this requires verification. Chytridiomycosis is a potential future threat.
This species does not occur in any protected areas. There are no conservation measures in place.
