Habitat:
This rodent occurs in the arid Chaco, and is typically found in dry, low, flat thorn scrub. It probably can be found in both primary and secondary habitat. It digs large burrows, conspicuous by the extensive piles of dirt outside the entrances. Females have been caught with one and two embryos. In captivity its gestation period is 77 days; the litter size averages 1.5 (range 1 to 3) (Mares et al. 1981; Wilson and Kleiman 1974).
Range:
This species occurs in the Chaco ecoregions of extreme southern Bolivia, Paraguay, and northwestern Argentina as far south as Cordoba Province (Dunnum 2015). It occurs in a number of protected areas as well, including the Kaa-iya del Gran Chaco National Park and Integrated Management Natural Area in Bolivia and the Defensores del Chaco National Park in Paraguay (Lacher 2016).
Conservation:
It is probably present in some protected areas in Argentina, Bolivia and Paraguay.
