The animals reach a head trunk length of 8.6 to 12.1 cm, have a 11.2 to 13.5 cm long tail and reach a weight of 15 to 40 g. The gray-brown tail is about 20% longer than the head and torso combined.

There are narrow, dark circles around the eyes. The underside of the body is whitish to orange with a narrow white stripe down the center of the chest. The fur is long. The feet are narrow. In older males, the metatarsus is covered with tubercles. Females do not have a pouch. The number of teats is unknown.
