This species is known from five lagoons on the Somuncura Plateau, an isolated basaltic plateau in Río Negro Province, Argentinean Patagonia, at an altitude of 1,000-1,200m asl.
Habitat and Ecology
The species inhabits steppe tablelands that contain a number of temporary shallow lagoons scattered over the volcanic plateau. Breeding takes place in permanent pools. It is not present in modified habitats.
It is a rare species.
It is threatened by eutrophication of its aquatic habitat, and the trampling of the shallow ponds by livestock (sheep and goats).
The entire population of this species is included within the Somuncura Provincial Reserve; however, this Reserve requires better management, since it affords no real protection for the area. Further surveys are needed throughout the Somuncura Plateau area to better establish the population status of this species.
