This mouse is known from southeastern Puebla, Mexico. Its back is tawny, its underside creamy white, and its tail is long. The source leaves open the possibility that it is a subspecies of a close relative.
The back is tawny with dusky hairs mixed in. The underside is creamy white, and the long tail is bicolored above and below.
Its wild activity is poorly known. The account suggests it may be nocturnal and, based on its long tail, possibly arboreal; these are inferences rather than confirmed observations.
An extinction-risk assessment has not been added yet.
