Ocellar setae present but fine, or strong; outer vertical setae present; inner vertical setae absent. Face black with grey pruinosity. Parafacial black with grey pruinosity, bare, 0.7­0.8 times as wide as first flagellomere. Lower margin of face slightly projecting; brown and black with grey pruinosity. Vibrissa well differentiated; intervibrissal distance 2.5 times distance between vibrissa and eye on same side; facial ridge with bristles on lower 1/5. Gena brown and black with grey pruinosity; hairs black; height 0.08 times eye height. Lunule black and shining; sublunular bulla indistinct. Antenna black; first flagellomere 1.2 times as long as pedicel; arista thickened on basal 0.3. Length of oral opening 1.3 times its width. Occiput flattened, white pruinose; hairs black. Palpus yellow and brown. THORAX .
