Body length: 6.5­8.5 mm.

MALE: HEAD. Head compressed anteriorly. Vertex 0.12­0.13 times as wide as head width; eyes separated by a distance wider than or as wide as ocellar triangle. Fronto­orbital plate black with grey pruinosity, 1­2 rows of hairs laterally. Frontal vitta parallel, reddish brown. Frontal vitta at base of antennae 1.1­1.2 times as wide as fronto­orbital plate anteriorly. Ocellar setae present but fine; outer vertical setae present; inner vertical setae absent. Face black, strongly grey pruinose. Parafacial black with grey pruinosity, bare, 1.8­2.2 times as wide as first flagellomere. Lower margin of face projecting, visible in profile, orange yellow or brown, grey pruinose. Vibrissa well differentiated; intervibrissal distance 1­1.2 times distance between vibrissa and eye on same side; facial ridge with bristles on lower 1/4. Gena brown to black with grey pruinosity; hairs white; height 0.1­0.2 times eye height. Lunule black and shining; sublunular bulla indistinct. Antenna black; first flagellomere 1.1­1.2 times as long as pedicel; arista thickened on basal 0.25­0.3. Length of oral opening 1.8 times its width. Occiput flattened, white pruinose; hairs white. Palpus yellow, or brown.

THORAX. Mesoscutum strongly pruinose; 4 black longitudinal vittae, with fine black hairs. 0+1 acrostichal seta; 0(1)+1 dorsocentral setae; 1­2 postpronotal setae; presutural supra­alar seta absent; 0­1 postsutural intra­alar seta; 2 notopleural setae; 1 supra­alar seta; 2 postalar setae. Pleuron grey and yellow pruinose; hairs white and yellow. Anepimeral setae hair­like; yellow or black; 1 katepisternal seta; 9­11 meral setae. Scutellum black with grey pruinosity, with two pairs of marginal setae; apical setae present and distinct; discal setae randomly arranged, not in rows. Subscutellum not very prominent. WING. Lower calypter hyaline white. Wing base without scale­like setae. Tegula black. Basicosta yellow. Wing hyaline, or pictured (rarely), narrow, or broad; petiole of apical cell 0.22­ 0.24 times as long as preceding section of R 4+5; M meeting R 4+5 at acute angle, or almost at right angle. Halter yellow. LEGS. Fore femur black; ventrally and laterally with whitish yellow hairs, dorsally with black hairs. Fore tibia black, with 1­2 p, apically with 1 p and 1 d. Fore tarus black. Fore claws brown, apex black; 1.2­1.3 times as long as fifth tarsomere. Pulvilli brown. Mid femur black; ventrally and laterally with whitish yellow hairs, dorsally with black hairs. Mid tibia black, with 1 ad and 1 v, apically with 1 ad, 1 av, 1 pv, 1 p, 1 v and 1 d. Hind femur brown to black; hairs black. Hind tibia black, slightly arched, with 5­ 6 ad, 3­5 pd and 3­4 v.

ABDOMEN. Abdominal tergites black; pruinosity yellowish silvery; longitudinal vitta absent; but with distinctly narrow black transverses. Relative length of abdominal tergites I+II:III:IV: V = 1.1:1:1:1.1; relative width I+II:III:IV: V = 0.3:1:0.9:0.7. Syntergite I+II pruinose. Pruinosity of tergite III silvery.

Ejaculatory apodeme small, knob­like. Hypandrium shorter than phallapodeme. Postgonite triangular. Pregonite shorter than postgonite, with sparse hairs dorsally. Phallus very broad and long, with fine white hairs dorsally; ventrolateral process with 4­5 small hooks; dorsolateral process hyaline, not sclerotized.

FEMALE. Body size slightly smaller than male. Wing hyaline. Eyes separated by a distance as wide as the flagellomere; not touching. Anterior spine­like setae of hind tibia absent. Sternite VII (sheath) slightly longer than sternite VI, flattened, broad apically, bent, apex directed ventrally, smooth ventrally; median area membranous; and the bent part of sheath rectangular in posterior view.
