Frontal vitta at base of antennae 0.3­0.35 times as wide as fronto­orbital plate anteriorly. Ocellar setae present but fine; outer vertical setae present; inner vertical setae present. Face brown to black with grey pruinosity. Parafacial brown to black with grey pruinosity; densely haired; 3­4 times as wide as first flagellomere. Lower margin of face slightly projecting, or perpendicular, not projecting; brown to black with grey pruinosity. Vibrissa not differentiated; intervibrissal distance 0.7­0.8 times distance between vibrissa and eye on same side; facial ridge with bristles on whole height. Gena brown to black with grey pruinosity; hairs black; height 0.35­0.4 times eye height. Lunule normal; sublunular bulla indistinct. Antenna black; first flagellomere 1.4­1.6 times as long as pedicel; arista thickened on basal 0.4­0.45. Length of oral opening 1.4­1.5 times its width.
