This species is currently only known from the Parque Nacional Calilegua, Jujuy Province, in north-western Argentina. The type locality of "Cerro de la Escalera, Orán Range, Salta Province", is unspecific and cannot be relocated, and therefore is not mapped here. It has an altitudinal range of 1,400-2,550m asl.
Habitat and Ecology
It is mostly aquatic and inhabits and breeds in streams in montane forest. The species is not known to occur in modified habitats.
It is a rare species.
The only known populations of this species are within a protected area. If the species occurs outside the Parque Nacional Calilegua, then threats might include selective logging, introduction of predatory fishes (trout), alteration of watersheds, and the impacts of mining operations. Chytridiomycosis is a potential future threat.
It is present in Parque Nacional Calilegua, although the reserve is in need of improved management. This species requires close population monitoring given that it is currently known from only a single site, and there is the potential threat of chytridiomycosis.
