New research has shown this species is more widely distributed than previously recognized. It is known from Buenos Aires and Entre Ríos in Argentina; from Santiago Vázquez to Arroyo Solís, in the margins of La Plata River, Uruguay and from one population at Cerro Colorado (Florida) and another from Rivera Department. It has an altitudinal range of 0-100m asl.
Habitat and Ecology
It occurs in seasonally flooded grasslands and rocky outcrops near rivers. It reproduces in temporary pools and its tolerance to habitat disturbance unknown.
It is rarely found except during reproductive periods. Its population status is unknown although this species was collected in both Uruguay and Argentina in 2002.
Pollution of soil and water due to agriculture, industries and human settlements are major threats. Habitat destruction is another threat to this species.
It occurs in the Punta Lara Reserve in Argentina.
Red List Status
Least Concern (LC)
Listed as Least Concern in view of its relatively wide distribution, presumed large population, and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category.
