DESCRIPTION

Body length: 3­5 mm.

MALE: HEAD. Head spherical or nearly so. Eyes separated by a distance slightly larger than or as wide as single ocellus. Fronto­orbital plate black, conspicuously swollen, grey pruinose (thinly), several rows of hairs laterally (reaching to eyes). Frontal vitta triangular, black. Frontal vitta at base of antennae 0.8­0.9 times as wide as fronto­orbital plate anteriorly. Ocellar setae strong; outer vertical setae present; inner vertical setae present. Face black with grey pruinosity. Parafacial black with grey pruinosity, haired; 1­1.2 times as wide as first flagellomere. Lower margin of face black, projecting, visible in profile, grey pruinose. Vibrissa well differentiated; intervibrissal distance 1.4­1.6 times distance between vibrissa and eye on same side; facial ridge with bristles on lower 5/8. Gena black with grey pruinosity; hairs black; height 0.13­0.15 times eye height. Lunule normal; sublunular bulla indistinct. Antenna black; first flagellomere 1.2­1.3 times as long as pedicel; arista thickened on basal 0.4­0.5. Length of oral opening 1.4­1.6 times its width. Occiput flattened, greyish yellow pruinose; hairs black. Palpus black.

THORAX. Mesoscutum shining, without pruinosity, with fine black hairs. 0+1 acrostichal seta; 1+2 dorsocentral setae; 2 postpronotal setae; presutural supra­alar seta present, but fine; 1 postsutural intra­alar seta; 2 notopleural setae; 1 supra­alar seta; 2 postalar setae. Pleuron thinly grey pruinose; hairs black; and without scale­like setae. Anepimeral setae medium size; black. 2 katepisternal seta. 5­8 meral setae. Scutellum black; shining, without pruinosity, with two pairs of marginal setae; apical setae present and distinct; on apex; discal setae randomly arranged, not in rows. Subscutellum not very prominent.

WING. Lower calypter white with light brown infuscation. Wing base without scale­like setae. Tegula black. Basicosta black. Wing hyaline, narrow; petiole of apical cell 0.3­0.35 times as long as preceding section of R 4+5; M meeting R 4+5 almost at right angle. Halter yellow or brown. LEGS. Fore femur black; hairs black. Fore tibia black; 0 ad; 0 a; 0 av; 0 v; 0 pv; 0 p; 0 pd; 1 d (apical). Fore tarus black. Fore claws black; 0.9­1 times as long as fifth tarsomere. Pulvilli black. Mid femur black; hairs black. Mid tibia black; 2 ad (1 apical); 1 a (apical); 1 av (apical); 1 pv (apical); 2 p (1 apical); 0 pd; 2 v (1 apical); 1 d (apical). Hind femur black; hairs black; scale­like setae absent. Hind tibia black; with 5 ad, 4 pd, 0 v. ABDOMEN. Abdominal tergites black, with thin grey pruinosity only. Relative length of abdominal tergites I+II:III:IV:V = 1.2:1:1:1.1; relative width I+II:III:IV:V = 0.5:1:1:0.6. Hair spots indistinct. TERMINALIA. Syncercus with a shallow notch posteriorly and a pair of hooks posteroventrally. Surstylus flattened, longer than cercus. Ejaculatory apodeme small, knob­like. Hypandrium as long as phallapodeme. Postgonite long, pointed. Pregonite reduced, but broad, with sparse hairs dorsally. Phallus slender, 1.2­1.3 times as long as hypandrium, with fine hairs dorsally. Distiphallus not well sclerotized.

FEMALE. Body size sometimes smaller than male. Wing hyaline. Eyes touching. Anterior spine­like setae of hind tibia absent. Sternite VII (sheath) longer than sternite VI; thin, broadly flattened; broad apically; slightly bent, apex directed ventrally; almost smooth ventrally. Ovipositor slightly bent downward.
