Lower margin of face perpendicular, not projecting, orange yellow, yellow pruinose. Vibrissa not differentiated; intervibrissal distance 0.8 times distance between vibrissa and eye on same side; facial ridge with bristles on lower 1/2. Gena yellow or brown, yellow pruinose; hairs white; height 0.25 times eye height. Lunule black and shining; sublunular bulla indistinct.
