DESCRIPTION

Body length: 5­8.5 mm.

MALE: HEAD. Head compressed anteriorly. Eyes separated by a distance as wide as single ocellus. Fronto­orbital plate black with grey pruinosity, serveral rows of hairs laterally (densely, reaching to eyes). Frontal vitta extremely narrow, reddish brown. 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. Occiput flattened, without distinct pruinosity; hairs black. Palpus black.

THORAX. Mesoscutum shining, without pruinosity, with fine black hairs. 0+1 acrostichal seta; 0(1)+1 dorsocentral setae; 1­3 postpronotal setae; presutural supra­alar seta present, but fine; 0­1 postsutural intra­alar seta; 0­2 notopleural setae; 0­1 supra­alar seta; 0­2 postalar setae. Pleuron thinly grey pruinose; hairs totally black and brown; and without scale­like setae. Anepimeral setae hair­like, black; 0­1 katepisternal seta; 9­14 meral setae. Scutellum black, shining, without 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 brown to black. Wing base without scale­like setae. Tegula black. Basicosta black. Wing pictured, white with light brown infuscation, narrow; petiole of apical cell 0.2­0.24 times as long as preceding section of R 4+5; M meeting R 4+5 at acute angle. Halter brown. LEGS. Fore femur black; hairs black. Fore tibia black, with 3 a, apically with 0­1 ad, 1 a, 1 pv, 0­1 pd and 1 d. Fore tarus black. Fore claws black; 1­ 1.1 times as long as fifth tarsomere. Pulvilli black. Mid femur black; hairs black. Mid tibia black, with 1­2 ad, 3 p, 1­2 v, apically with 1 ad, 1 a, 0­1 av, 1 pv, 1 p, 1 pd, 1 v and 1 d. Hind femur black; hairs black; scale­like setae absent. Hind tibia black, with 6­7 ad and 5 pd.

ABDOMEN. Abdominal tergites black; pruinosity present, but thin; longitudinal vitta distinctly present (grey pruinose), with narrow transversal grey pruinosity between tergites. Relative length of abdominal tergites I+II:III:IV:V = 1.1:1:1:1; relative width I+II:III:IV:V = 0.4:1:1:0.6. Hair spots indistinct. TERMINALIA. Syncercus broad, Vnotched posteriorly. Surstylus flattened, broadened on apical half, upward, longer than cercus. Ejaculatory apodeme small, knob­like. Hypandrium as long as phallapodeme. Pregonite needle­like. Postgonite long, as long as pregonite, bent ventrally. Phallus 1.1­1.2 times as long as hypandrium, without fine hairs. Epiphallus well developed, bent ventrally. Distiphallus partly sclerotized.

FEMALE. Usually smaller than male. Wing hyaline. Eyes separated by a distance as wide as ocellar triangle; not touching. Anterior spine­like setae of hind tibia absent. Sternite VII (sheath) longer than sternite VI, tapered, narrow apically, bent, apex directed dorsally, sternite VII with linear wrinkles ventrally. Ovipositor bent upward.
