This species occurs in southern Brazil, Argentina (south to Chubut Province), Uruguay and Bolivia, from sea level up to 2,600m asl.
Habitat and Ecology
It is found at small ponds or bogs with stagnant water, in dry, temperate habitat, mostly in open areas. In Brazil and Argentina, it occurs mainly on the coastal zone. Males call at night from in the water or on the exposed edge of the water. Oviposition occurs in these temporary waterbodies and tadpoles feed and develop in the same site. It has adapted to anthropogenic disturbance.
It was abundant in 2003 in Argentina.
It is collected for educational and scientific use and threatened by mistreatment from children and by road kills, but the species in general is not threatened.
Taxonomic research to determine the status of populations should be carried out. It occurs in several protected areas.
Red List Status
Least Concern (LC)
Listed as Least Concern in view of its wide distribution, tolerance of a broad range of habitats, presumed large population, and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category.
This species might comprise a complex of more than one species. There are two subspecies in Argentina: R.a. mendocinus and R.a. arenarum.
