Distribution

This species is known only from type locality (the original location this species was found) at Salar de Pipanaco in Catamarca province, Argentina

Habitat and Ecology

The habitat consists of perisaline shrublands associated with the salt pans of Pipanaco. Low shrubs dominate the area and the substrate is mainly sand with significant amounts of salt. The animals are restricted to a narrow band of high salt concentration (halophytic) plant habitat that lies between the bare salt and the more typical Monte Desert habitats.

The golden Vizcacha rat digs burrows in mounds at the base of shrubs, with multiple individuals living in these burrows.
