From the IUCN Red List Species Account:


Range Description

This species can be found in the Pampean region of Argentina (Buenos Aires, Córdoba, Entre Ríos, La Pampa, Mendoza and Santa Fe), Uruguay (Rocha and San José), and Rio Grande do Sul, Brazil, from 0-500m asl.

Habitat and Ecology

This frog occurs in grasslands on the ground near temporary waterbodies, and also occurs in roadside ditches and in irrigated cropland. The eggs are laid on the bottom of temporary ponds.


It has apparently disappeared from at least two sites in Uruguay (Rocha, in Laguna de Castillos, and San Jose, in Delta del Tigre). It is rare in Argentina.

Population Trend


Major Threats

Habitat loss (due to agricultural development and housing development) is a major threat, as is water and soil pollution due to agriculture, industry, and human settlement. It is sometimes subject to persecution because of unfounded beliefs that it is venomous. It is also collected for the international pet trade and its eggs are sold internationally for scientific research.

Conservation Actions

It occurs in some protected areas.

Red List Status

Near Threatened (NT)


Listed as Near Threatened because this species is in significant decline (but at a rate of less than 30% over ten years) because it is subject to intense persecution, making the species close to qualifying for Vulnerable.
