A medium-sized mouse with large ears, long hind feet and an extremely long tail. Little is known about the ecology of this species. It is thought to be nocturnal, living in underground burrows during the day and searching for food up in the trees at night. The species is known from a single locality, and is likely to be declining as a result of habitat degradation. Its forest habitat suffered from frequent fires during the dry season, and cattle are encroaching onto the reserve in which it lives.
