This small rodent is found in the Peruvian Andes. It has been recorded in high-elevation grasslands, fields, and sparse woodland, but its diet and activity are poorly documented.
The back ranges from brown to pale olive and is heavily lined with black. The underside hairs have whitish or buffy tips, and the densely furred tail is sharply bicolored.
The account provides no specific information on diet, activity, or breeding. These parts of its natural history therefore remain undocumented in the source used here.
An extinction-risk assessment has not been added yet.
