This species can be found from 300-750m asl in Misiones, Argentina; Tres Baras de Paraná, Paraná, Brazil (here, its range is severely fragmented); and Itapua Department, Paraguay.
Habitat and Ecology
It occurs near permanent streams (in which it breeds) in rainforest, and probably does not tolerate habitat disturbance.
It is common in its limited range.
Threats to this species include selective logging, clear-cutting of primary forests, pollution of soil and water due to agricultural practices, and industrial pollution by organic wastes. The introduction and spread of Rana catesbeiana is also a threat to this species.
It occurs in Parque Estadual Rio Guarani, Brazil, and in Argentina in the Reserva de la Biósfera Yabotí, Parque Nacional Iguazú, and several provincial reserves.
Red List Status
Near Threatened (NT)
Listed as Near Threatened because its Extent of Occurrence is probably not much greater than 20,000 km2, and the extent and quality of its habitat are probably declining, thus making the species close to qualifying for Vulnerable.
