Habitat and Ecology
This is an aquatic species that inhabits dry scrubland and semi-arid areas. They breed in temporary pools and water tanks on cattle farms. During the dry season they burrow underground and wait for rain before emerging again. They have a very short breeding season and the tadpoles develop rapidly.
It is an uncommon species throughout its range.
It is threatened in Argentina by the destruction of Chaco habitat for agriculture and wood extraction, land and water pollution caused by agrochemical runoff.
Its range includes Parque Nacional Defensores del Chaco in Paraguay. In Argentina, occurs in the Chaco, Río Pilcomayo, and Copo National Parks, the Los Colorados Private Reserve, and the Teuquito Multiple Use Reserve. More research into the species' distribution, ecological requirements and population status is needed.
