Frontal vitta at base of antennae 2.5 times as wide as fronto­orbital plate anteriorly. Ocellar setae strong; outer vertical setae present; inner vertical setae absent. Face brown to black, greyish yellow pruinose. Parafacial brown to black, greyish yellow pruinose, bare, 0.9 times as wide as first flagellomere. Lower margin of face slightly projecting, visible in profile, orange yellow, yellow pruinose. Vibrissa well differentiated; intervibrissal distance 1.1 times distance between vibrissa and eye on same side; facial ridge with bristles on lower 1/6. Gena brown, yellow pruinose; hairs black; height 0.12 times eye height. Lunule brown, normal; sublunular bulla indistinct. Antenna brown to black; first flagellomere 2.1 times as long as pedicel; arista thickened on basal 0.33. Length of oral opening 1.2 times its width.
