Frontal vitta at base of antennae 1­1.1 times as wide as fronto­orbital plate anteriorly. Ocellar setae present but fine; outer vertical setae present; inner vertical setae absent. Face black with grey pruinosity. Parafacial black with grey pruinosity, bare, and as wide as first flagellomere. Lower margin of face, black, shining, not pruinose. Vibrissa well differentiated; intervibrissal distance 1.2­1.3 times distance between vibrissa and eye on same side; facial ridge with bristles on lower 1/6. Gena black with grey pruinosity; hairs white; height 0.1 times eye height. Lunule black and shining. Antenna black; first flagellomere 1.3­1.4 times as long as pedicel; arista thickened on basal 0.25. Length of oral opening 3.1­3.2 times its width. Occiput flattened; greyish yellow pruinose; hairs black. Palpus brown.
