Descriptive notes. Head-body 101-125 mm, tail 97-115 mm, ear 16-19 mm, hindfoot 16-19 mm; weight 31-50 g. Dorsal pelage of the Smoky Oldfield Mouse is long and soft. Dorsum is a mixture of dusky neutral gray and pale neutral gray, darkest along back. Venteris pale neutral gray, not countershaded with dorsum. Mystacial vibrissae are moderately long, extending slightly beyond posterior margin of pinnae when bent. Tail is short, comparatively thick, thinly haired, and uniformly colored, without terminal white tip; annular rings are conspicuous. Hindfootis short, with metatarsals light brown washed with white hairs. Hallux is short. Females have six mammae: one postaxial pair, one abdominal pair, and one inguinal pair.
Habitat. Montane forests at elevations of 2438-2851 m. Smoky Oldfield Mice have been caught in dense secondary vegetation, subalpine rainforest, and upper montane rainforest; on the ground; in runways through wet leaf litter and mossy debris; beneath mossy logs, branches, or roots; and inside trunk of a hollow tree. In Sangay National Park, one individual was recorded in pristine forest dominated by trees with knotty branches and abundant epiphytes; Chusquea sp. bamboos dominated the understory.
