From the IUCN Red List Species Account:

Range Description

This species is known from the Chaco of Paraguay (in Central, Presidente Hayes, and Alto Paraguay Departments) and northern Argentina (in Chaco, Cordoba, Corrientes, Formosa, Santa Fe, and Santiago del Estero Provinces). In Paraguay it occurs up to 200m asl.

Habitat and Ecology

It inhabits dry scrubland and semi-arid areas, and breeds in temporary pools and water tanks on cattle farms. In Argentina, it occurs in vegetation near saline lakes. During the dry season individuals burrow underground and wait for rains before emerging again. The breeding season is short and larval development is rapid.

Population

It is a common species in Paraguay but is very rare in Argentina, where it was last collected in 1986. Extensive work in an area in Cordoba where it was once recorded has not turned up any recent specimens.

Population Trend

Decreasing

Major Threats

This species can be threatened by fires, and potentially also by over-grazing by livestock.

Conservation Actions

Its range includes Parque Nacional Defensores del Chaco in Paraguay, although it is not known from any protected areas in Argentina.
