This species occurs in central and south-central Argentina. It has an altitudinal range of 50-1,500m asl.
Habitat and Ecology
This species can be found in montane forests, rocky outcrops, and scrub habitats. It reproduces in permanent streams. The larvae remain in streams where metamorphosis occurs after about eight months. It tolerates substantial habitat destruction.
It is less common than other Odontophrynus in Argentina but regularly recorded.
It is threatened by water pollution and fires caused by agricultural and mining activities.
It occurs in the Pampa de Achala Regional Hydrological Reserve, Cordoba, Argentina.
Red List Status
Least Concern (LC)
Listed as Least Concern in view of its wide distribution, tolerance of a degree of habitat modification, presumed large population, and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category.
This form is probably a complex of more than one species.
