This small mouse is recorded from humid mountain habitat in Mexico. Its type locality is at about 2,570 m, and the original description notes chestnut-colored fur on the back.
The dorsal fur is described as soft, dense, and chestnut-colored.
The type specimen came from an isolated patch of cloud forest on the northern slope of the Cordillera Neovolcánica in Estado de México. This describes the type site, not the species’ full range or habitat preference. Diet and behavior were not reported.
An extinction-risk assessment has not been added yet.
