From the IUCN Red List Species Account:


Range Description

This species occurs in the southern part of Misiones Province, Argentina, and Rivera, Tacuarembó, and Cerro Largo Departments in Uruguay at elevations of 150-350m asl.

Habitat and Ecology

It occurs in open areas with rocky outcrops, but also occurs in the ecotones between grasslands and forests of Astronium balansae. In Uruguay, it has been found in eucalyptus plantations. Nothing is known about its breeding habits, other than that males have been found in amplexus in temporary streams and the larvae presumably develop in streams.


It is very rare in Misiones (Argentina) where males have been found (in 1998 and 2003) in amplexus with females of other species, possibly because of a lack of conspecifics. The population status of the species in Uruguay is unknown.

Population Trend


Major Threats

The pollution of soil and water due to agricultural practices is a known threat to this species. In Misiones, it is also threatened by the conversion of native habitat to pine plantations.

Conservation Actions

It occurs in small provincial parks in Argentina, including Fachinal and the Campos San Juan private reserves. Broad-scale conservation actions are necessary to combat the effects of pollution on its breeding habitat.
