The scientific name "humeralifer" roughly translates as "wearing a shoulder cape" and refers to the mantle of light grey fur that covers the animal's shoulders. There are also patches of whitish fur on the hips, but otherwise the body is black with irregular grey spots over the back and flanks, and yellowish on the underparts. The limbs are black, apart from grey fur stretching down over the outer surface of the upper arms from the mantle.
