Redescription. Male ( Figs 50–54 ). Body length 11.6–11.9 mm (excluding antenna, n = 14), wing length 14.2–14.8

mm (n = 14), length of antenna 4.2–4.8 mm (n = 14). General body coloration yellow.

Head. Generally yellow, vertex and occiput with dark brown linear mark. Tubercle distinct in lateral view ( Fig. 50 ). Rostrum yellow in dorsal part, yellowish-brown in ventral part, nasus yellow, slightly curved, short and stout, densely covered with black setae. Antenna 13-segmented, if bent backward reaching base of 2 nd abdominal segment. Scape and pedicel yellow, flagellum with first flagellomere expanded medially, yellowish, rest of flagellomeres black. Apical flagellomere very small, oval. Each flagellomere except for first with basal enlargement, longest verticils subequal in length to their corresponding flagellomeres. Whole flagellum densely covered with short and light setae. Palpus with basal two segments light brown, rest of segments yellow, slightly longer than basal three segments together.

Thorax. Pronotum yellow, brownish in middle and lateral areas. Prescutum and presutural scutum yellow with four greyish-brown stripes, median stripes narrowed at base and gradually expanded to obtuse apex, merging apically and possessing black median vitta in apical third, lateral stripes rounded apically, darker in coloration on inner side ( Fig. 51 ). Interspace between median and lateral stripes yellowish with light and short setae. Scutum yellow, each lobe with two brown triangular markings connecting to each other ( Fig. 51 ). Scutellum yellow, with dark median vitta. Postnotum yellow with thin dark vitta. Pleuron entirely yellow ( Fig. 52 ). Legs with coxae, trochanters and basal fifth of femora yellow, rest of femora brown with tip black, with yellow preapical ring, tibiae and tarsi entirely black. Halter with stem yellow, knob yellowish-brown. Wing light brown, variegated by light areas, including apical area of cell c, median area of 1 st cell of r 1, base of stigma, light band across apical area of cell r 1, base of cells r 3, r 4 and r 5; other light area including base and apical areas of bm; stigma dark brown ( Fig. 53 ). Venation: R 1 atrophied in basal two thirds, R 2+3+4 longer than R 3, R 4 subequal in length to Rs, R 5 curved in apical half, r-m subequal in length to base of R

, discal cell narrow, of almost same length as petiole of cell m 1, cell m 1 nearly three times longer than its petiole ( Fig. 53 ).

Abdomen. Basal five abdominal segments yellow with brown lateral and median stripes, rest of abdominal segments including hypopygium black ( Fig. 54 ).

Hypopygium. Male hypopygium with tergite nine and sternite nine separated apically ( Fig. 55 ). Tergite nine divided mid-dorsally by pale region, dorsal portion shallowly emarginated at posterior border, straight laterally, apical half densely covered with setae ( Figs 55, 56 ). Ventral portion of tergite nine reduced into narrow yellow plate terminating into two small oval lobes ( Fig. 56 ). Gonocoxite broad basally, producing into powerful spine directed inward, with many long setae on lateral surface ( Figs 55, 57, 58 ). Outer gonostylus flattened, blackened, broad medially, densely covered with short setae ( Fig. 59 ). Inner gonostylus with upper beak relatively stout, lower beak obtuse, black stripe suffused along margins of beaks ( Fig. 59 ). Sternite nine concave medially, appendage of sternite nine with ventral lobe rounded and densely covered with long setae ( Fig. 58 ). Adminiculum broad basally and narrowed to acute apex in dorsal view, sinuate at ventral margin in lateral view; median sclerite conspicuous ( Figs 57, 58 ). Semen pump with compressor apodeme fan-shaped, medially with deeply V-shaped notch, each arm broad and truncated apically, slightly longer than posterior immovable apodeme ( Fig. 60 ). Posterior immovable apodeme with paired arms slightly straight, terminating into sharp apex in lateral view ( Figs 61, 62 ). Anterior immovable apodeme broad, flattened, rounded in dorsal view ( Fig. 62 ). Aedeagus thick at base, gradually narrowed to apex, more than 4.5 times longer than semen pump ( Fig. 62 ).

Female. Body length 19.1–22.7 mm (excluding antenna, n = 9), wing length 17.4–20.1 mm (n = 9), length of antenna 2.7–3.1 mm (n = 9). Generally similar to male in body coloration. Antenna relatively short, if bent backward reaching before base of wing.

Female terminalia. Tergites nine and ten shining brown. Cercus brown, with tip narrowed and curved dorsally, ventral margin with rough serration ( Figs 63, 64 ). Hypovalva short, strongly reduced, terminating in two narrowed pale plates, acute apically ( Figs 64, 65 ). Median incision between hypovalvae almost same depth to posterior margin of sternite eight ( Fig. 65 ). Lateral incision absent. Sternite nine with anterior parts flattened and concave medially ( Fig. 66 ). Posterior part of sternite nine covered with short filaments, shovel-shaped, medially with groove, posterior margin medially inconspicuously convex, laterally with very small incisions ( Fig. 66 ). Anterior parts of sternite nine lightly curved in middle length. Furca in shape of narrow filament ( Fig. 67 ). Spermatheca spherical ( Fig. 68 ).
