This species is known from Uruguay (in the departments of Canelones, Florida, Lavalleja, Maldonado, Montevideo, Rocha, San José and Treinta y Tres, Artigas, Durazno, and Río Negro) and from Brazil (Rio Grande do Sul), from 0-1,100m asl.
Habitat and Ecology
It occurs in coastal sand plains, open savannahs, rocky outcrops, grasslands and open montane habitats, and probably does not tolerate habitat disturbance. Breeding takes place in temporary pools.
This species is rare and occurs in widely scattered populations. It is probably extinct in Montevideo Department because of habitat destruction.
The main threat is habitat destruction due to encroaching cultivation of crops, establishment of pine plantations, and encroaching human settlements.
It occurs in Floresta Nacional de São Francisco de Paula.
Red List Status
Near Threatened (NT)
Listed as Near Threatened because this species is probably in significant decline (but probably at a rate of less than 30% over ten years) because of widespread habitat loss through much of its range, thus making the species close to qualifying for Vulnerable.
This form is probably a complex of more than one species. It was long confused with Pleurodema thaul, until the work of Donoso-Barros (1969).
