The Jujuy tuco-tuco is a pale-brown rodent recorded in Jujuy Province in northwestern Argentina. Current records are limited to one locality, and uncertainty remains about its range and taxonomy.
The species account describes pale-brown fur, a pale half-collar reaching toward the ears, a dark muzzle, whitish hands and feet, and a pale tail ending in a dark tuft.
At the type locality in Jujuy Province, it was reported from stony ground on ravines that descend toward the river. Population studies have not been conducted, and natural-history information remains limited.
An extinction-risk assessment has not been added yet.
