This species is known from the type locality, Cambará do Sul, and from 80km to the south-west in Sao Francisco de Paula, in the state of Rio Grande do Sul, Brazil, at 900-1,100m asl. Its distribution is not well knon because its explosive breeding habits make it difficult to survey.
Habitat and Ecology
This species occurs in open grassy habitats and borders of auracaria forest, where it breeds after rains in flooded areas near small streams or ditches, with the eggs being deposited between stones in shallow water.
It has apparently disappeared from the type locality but persists at Sao Francisco de Paula.
Fire and habitat loss due to cattle ranching are threats to this species, and it is potentially threatened by the international pet trade.
It occurs in Parque Nacional da Serra Geral and Floresta Nacional de São Francisco de Paula. It is listed as vulnerable in the Rio Grande do Sul state threatened list.
Red List Status
Data Deficient (DD)
