From the IUCN Red List Species Account:

 

Range Description

This species is endemic to north-western Argentinean Patagonia, and has been recorded from a number of localities in Neuquen Province. The altitudinal range is from 1,000-1,500m asl.

Habitat and Ecology

It lives on the ground under stones and in humid ravines surrounding small-scattered lagoons, in volcanic tablelands, with steppe and semi-desert landscapes; it is presumed to breed in the lagoons. The species does not occur in modified habitats.

Population

It is a rare species.

Population Trend

Decreasing

Major Threats

The main threat is the introduction of predatory fishes (perch and salmonids) in Laguna Blanca, but it is also threatened by the loss of pond side vegetation through overgrazing and trampling by livestock (sheep).

Conservation Actions

The species was previously protected in Parque Nacional Laguna Blanca; however, it is now extirpated in this park because of the introduction of predatory fishes and habitat loss. Three of the subspecies lack any protection, and habitat protection is urgently needed as are measures to prevent the future introduction of predatory fish species.

Taxonomic Notes

The Atelognathus praebasalticus complex needs to be re-examined taxonomically. There are four known subspecies, some of which may constitute new species. Some of these subspecies may be extinct.
