Its back is dark grayish brown to blackish gray, with silvery-gray fur underneath. Examined specimens come from eastern Panama, where premontane rainforest is considered a likely habitat.
The dorsal fur is dark grayish brown to blackish gray, and the ventral fur is silvery gray. The backs of the forefeet have dark fur contrasting with whitish digits; the tail is longer than head and body combined.
The revision considers premontane rainforest a likely usual habitat, based on specimen localities. It does not report direct behavior observations for this species here.
