Ears are short, rounded, and dark gray, with margins of inner surfaces covered with short and thin black hair. Flanks are similar to dorsum but slight ly lighter. Venter is ashy gray, with each individual hair dark gray at bases and white at tips. There is a small patch or some white hair under chin and in inguinal area. Forefeet and hindfeet are covered by short brown hairs dorsally. Ungual tufts are whitish, shorter than claws on forefeet and longer than claws on hindfeet; claws are moderately long, keeled for c.33-50% of their length. Tail is slightly bicolored, dark gray above and ashy gray below.
