Males have small white cheek patches that extend as far up as the eye's corner, and thin white hair partially encircles the upper lip and totally encircles the lower lip, terminating in a black chin. Males have small, light buff cheek patches that extend to the bottom of the orbital ridge and can be slightly separated at the throat. Females are generally smaller than H. l. leucogenys females and have a black fringe at the ears. Females are generally buff to strawberry-buff and can have a very slight grizzling of darker hairs on the chest, on edges and tips of fingers and toes, and on the outer forearm. Adult females may have slight red-brown genital hairs, and usually there is a trace of a white fringe encircling the face.
Females are typically smaller than males.
