Figs. 44–47  
 Diagnosis   
 Medium­sized fly; abdomen broadly yellowish with black median longitudinal vitta and apex in male, abdominal syntergite 1+2 excavated to posterior margin with rather fine median marginal setae, tergites 3 and 4 without median discal setae; antenna with pedical and flagellomere 1 reddish brown, 3+3 dc.   
Body length 12.3–15.6 mm.  
 Description Male. Head black in ground color, facial carina yellowish and gena brownish, with dense pale yellowish gray or grayish white pruinosity; antenna dark brown, scape, pedicel and basal portion, at most basal 1/3, and inner side of flagellomere 1 reddish; palpus brownish, sometimes reddish yellow on apical 1/3 or less. Vertex about 1/8 head width; parafacial 3–4 times as wide as flagellomere 1 in lateral view; facial carina weakly rounded or rather flattened on anterior surface, arched in lateral view; gena about 2/5 eye height; lower margin of face weakly protruding forward, more or less extending beyond vibrissal base. Fronto­orbital plate sometimes with short and fine sparse hairs; parafacial bare; inner vertical seta about 2/5 eye height, about 2/3 as long as ocellar seta; outer vertical seta indistinct; 10–16 inclinate frontal setae, uppermost one about as long as inner vertical seta; vibrissa inserted slightly above level of lower margin of face; occiput with 1–2 rows of black hairs behind postocular setae. Antenna falling short of lower margin of face by about 2/3 length of flagellomere 1; base of antenna at the level of lower 1/3–1/4 of eye height; pedicel with 1–2 long setae about as long as flagellomere 1; flagellomere 1 about 4 times as long as pedicel; arista including plumosity about twice as wide as flagellomere 1; prementum about 4 times as long as wide; palpus about 1.2 times as long as antenna.   
 Thorax black in ground color, with grayish pruinosity, postpronotal lobe sometimes reddish; 3 broad black longitudinal vittae present, inner vitta sometimes separated into 3 narrow vittae on presutural region of scutum; scutellum black, sometimes reddish on apical portion, with grayish pruinosity on posterior 1/2. Postpronotum with 3–5 setae; 2+2–3 ac, 3+3 dc, 0+3 ia, 4 sa; scutellum with 2–4 discal setae, basal scutellar seta about twice as long as scutellum and subequal in length to subapical seta, apical seta slightly longer than scutellum, discal seta suberect and subequal in length to apical seta. Wing hyaline, slightly tinged with pale brown especially along veins; tegula dark brown; basicosta brown; calypter pale yellowish brown. Costal spine absent; relative length of second, third and fourth costal sections approximately as 2:2.5:1.5; basal node of R 4+5 with 3–5 hairs dorsally and ventrally; vein M from dm­cu crossvein to its bend about 2.5 times as long as distance between the bend and wing margin; cell r 4+5 open. Legs black, pulvilli yellowish. Fore tibia with 2 fine p; mid tibia with 1 ad, 2–3 p and 1 v, all setae short and fine; hind tibia with 2–3 ad, 3 pd and 1–2 v, apical pv indistinct.   
 Abdomen broadly reddish yellow, black median longitudinal vitta distinct on syntergite 1+2 to tergite 4, tergite 4 with small black triangular posterolateral spots and tergite 5 with broad median black vitta and diffusing marginally or mostly; rather thin whitish pruinosity on anterior 1/4 of tergites 3, on 1/3 of tergite 4 and on entire tergite 5. Syntergite 1+2 excavated to posterior margin, with 2 median marginal and 1–2 lateral marginal setae; tergite 3 with 2 median marginal and 1 lateral marginal setae; tergite 4 with a row of marginal setae; tergite 5 with an irregular row of rather short discal and a row of strong marginal setae; discal setae absent on tergites 3 and 4. Sternite 5 nearly square, median cleft wide, lateral lobe about 1/2 depth of the sternite. Male terminalia. Cerci strongly narrowed on apical 1/2 and pointed at apex in dorsal view; in lateral view surstylus wide and bluntly rounded apically; postgonite shorter than basiphallus; distiphallus with spinules on upper 2/3 of membranous surface ventrally, membranous apical part 1/2 length of sclerotized basal part.   
 Female. Differing from male as follows: Vertex wide, slightly more than 1/4 head width; inner vertical seta about 1/2 eye height or as long as ocellar seta; outer vertical seta about 1/2 inner seta length; 1 prevertical seta subequal in length to outer vertical seta; 2–3 proclinate orbital setae slightly shorter than ocellar seta; gena wide, about 1/2 of eye height; 2+2–3 ac; all setae on legs stronger than in male, mid tibia with 2 ad; claw and pulvillus slightly shorter than 5th tarsomere; abdomen broadly reddish brown or dark brown, median longitudinal portion blackish; dorsum evenly and thinly covered with grayish white pruinosity that has shifting appearance with direction of light; abdominal syntergite 1+2 without median marginal seta, tergite 5 without discal seta.
