A rodent of arid and semiarid western Argentina. It is reported to favor sandy soils with sparse shrubs, but its range limits remain unresolved.
The long, lax fur is pale yellow brown with a white underside. The nose and mouth area are white, with pale patches near the eyes and ears.
It is reported mainly from arid and semiarid habitats, favoring sandy soils with sparse shrubs. The strength and generality of that preference still need study, including comparisons where related species occur together.
