Habitat:
This species occurs in cloud forest and wet conifer-oak forest over an altitudinal range of 1,300 to 3,000 meters. It prefers dense, waist-high herbaceous cover at the edge of wet pine-oak forest. Sometimes it can be found using runways, which are common in the moss root that cover the forest floor (Robertson and Rickart 1975). Females with three embryos were taken in May and October. Apparently, at least some reproduction occurs in both the wet and dry seasons. This species make their burrows under logs or rocks or use mouse burrows (Ceballos 2014).

Range:
This species is geographically restricted to Oaxaca, Mexico where it is endemic to the "island habitats" (Ceballos 2010). This is based off of predictions of distributions using ecological niche modelling (Illoldi-Rangei et al. 2004). It occurs from 1,500 to 2,850 m asl. Within the north-central region of Oaxaca this species is restricted to Sistema Montanoso where there have been sightings from Vista Hermosa and the surrounding area. In addition, it is also known from Llano de las Flores at 2,800 m and Totontopec (Robertson and Rickart 1975).

Conservation:
This rodent occurs in several protected areas (D. Tirira pers. comm).
