This species is known only from north-western Corrientes Province, Argentina, between 50 and 70m asl.
Habitat and Ecology
It occurs in seasonally inundated grasslands where it also reproduces. When breeding areas dry up it usually occurs underground. Its tolerance to habitat disturbance is unknown.
It is known from only a few localities but it is common and its population is stable in suitable habitats.
Loss of habitat due to the expansion of human settlements is a threat to this species, most notably the growth of the city of Corrientes.
It is not known to occur in any protected areas.
Red List Status
Near Threatened (NT)
Listed as Near Threatened because its Extent of Occurrence is not much greater than 20,000 km2, and the extent and quality of its habitat are probably declining, thus making the species close to qualifying for Vulnerable.
