Lower margin of face projecting, visible in profile, brown, grey pruinose. Vibrissa well differentiated; intervibrissal distance 0.9 times distance between vibrissa and eye on same side; facial ridge with bristles on lower 1/3. Gena brown and black with grey pruinosity; hairs white; height 0.12 times eye height. Lunule black and shining; sublunular bulla indistinct.
