General body coloration yellow. Male body length 9.1–10.6 mm, of female 7.3–12.1 mm, wing length of male 10.7–12.6 mm, of female 9.6–12.3 mm. Wing reaches distinctly beyond tip of abdomen in both sexes.
Head. Dark brown, dusted with gray. Male antenna 1.8–2.2 mm long, female antenna 1.7–2.3 mm long, 14- segmented. Scape elongate, nearly cylindrical, brown. Pedicel short, yellow. Antennal flagellum light yellow, distal part slightly darkened. Flagellomeres elongate, wider at base. Verticils brownish, three times as long as respective segments. Rostrum, palpus and labellum dark brown to black.
Thorax. Cervical sclerite brown. Pronotum brown dorsally, yellow laterally. Mesonotal prescutum yellow with brown median stripe, that gets narower posteriorly. In some specimens it reaches posterior margin of sclerite, but in most specimens it presents only at frontal margin of prescutum. Scutal lobe yellow, median margin with brownish longitudinal line. Scutellum yellow. Mediotergite yellow with brownish spot or just narrow line at posterior margin. Pleuron uniformly yellow. Wing (Fig. 41) yellowish with three small but distinct brown spots at frontal margin: around base of Rs, tip of Sc and at R2, brownish area along cord, along distal margin of discal cell and along distal wing margin. Smoky areas in most cells, but most intense along posterior wing margin. Veins brownish. Venation: Sc long, Sc1 nearly reaching branching point of Rs, Sc2 reaching slightly beyond Sc1. Rs long, slightly arcuate. Basal deflection of CuA1 before branching point of M. Halter 2.0– 2.4 mm long in male, 1.4–2.2 mm in female, stem pale, knob brownish. Coxae and trochanters yellow. Frontal femur yellow with widely brown distal part and less distinct wide brownish ring at middle. Area between distal darkening and ring at middle yellow. Middle and posterior femora yellow with distinctly darkened distal part, but ring at middle indistinct. Tibiae yellow with darkened distal end, tarsi brown with yellowish base of first tarsomere. Male femur I: 6.0– 7.1 mm, II: 7.4–7.6 mm, III: 6.9–8.3 mm; tibia I: 8.0– 9.2 mm, II: 7.9–8.2 mm, III: 8.4–9.4 mm; tarsus I: 5.6–9.0 mm, II: 6.4–7.1 mm, III: 6.8–7.8 mm. Female femur I: 5.9–7.6 mm, II: 6.3–7.6 mm, III: 7.1–8.3 mm; tibia I: 7.8–9.5 mm, II: 5.9–8.3 mm, III: 7. 0–9.1 mm; tarsus I: 6.8–7.9 mm, II: 5.6–7.3 mm, III: 5.6–7.2 mm.
Abdomen. Yellow. Posterior and lateral margins of tergites and sternites slightly infuscated with brownish. Male genitalia (Fig. 42) brownish yellow. Ninth tergum narrower distally than frontally, with shallow emargination at posterior margin. Ventromesal lobe of gonocoxite very low. Gonostylus elongate, setose, turning narrower distally. Paramere wide, light, without distall elongation. Penis comparatively long, wide, bifid at apex, tip sharply curved downwards. Ovipositor (Fig. 43) yellow with darkened fronto-dorsal margin of hypovalva. Cercus long, obscure yellow, slightly arched and blunt-apexed.
Elevation range in Korea. This species was recorded at altitudes ranging from 40 m to nearly 800 m.
Period of activity. Adults are active and on the wing from late May through late June.
