From the IUCN Red List Species Account:


Range Description

This species is known from northern, central and eastern areas of Chacoan environments: Argentina (provinces of Chaco, Corrientes, Salta, and Formosa), Bolivia (departments of Santa Cruz and Tarija), and Paraguay (departments of Presidente Hayes, Boquerón, and Alto Paraguay). Its altitudinal range is from 0-200m asl.

Habitat and Ecology

It occurs in the dry and wet Chaco. It breeds in temporary and artificial ponds. Its adaptation to anthropogenic disturbance is not known.


It is common in the northern portion of its range. It is rare and declining in Argentina.

Population Trend


Major Threats

There are few threats at present, although the causes of the declines in Argentina are not understood, and fire and over-grazing by livestock could be involved. However, the possible future construction of a water channel to transport water from Río Paraguay to central Chaco will result in the introduction of a number of potential predatory fish species into Paraguay. Habitat destruction for agriculture is a threat in Argentina. It is sometimes found in the international pet trade but at levels that do not currently constitute a major threat.

Conservation Actions

It occurs in several protected areas.

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.
