Redescription. General body colouration brownish yellow. Body length of male 4.2–6.7 mm, of female 5.3–7.9 mm. Wing length of male 5.5–7.3 mm, of female 5.7–7.7 mm. Head. Brownish greyish yellow, pale grey pruinose frontally and along eye margin. Eyes widely separated in both sexes, distance between them at base of antennae exceeds lengths of scape and pedicel combined. Antenna 1.2–2.1 mm long in male, 0.9–1.7 mm in female, reaching to the wing base if bent backward. Both basal antennomeres yellow, scape slightly dusted with grey basally, elongate, nearly cylindrical, 2 × as long as pedicel, pedicel pear-shaped. Flagellum yellow basally, slightly darkened distally. Flagellomeres elongate, longest at middle, apical flagellomere smaller than penultimate. Verticils brownish, longest verticils approximately as long as respective segments. Rostrum pale brown, palpus darker brown, mouth parts pale brown. Thorax. Cervical sclerites yellow. Pronotum pale brown dorsally, yellow laterally, covered with long, sparse, erect, yellow setae dorsally. Mesonotal prescutum uniformly brownish yellow, without stripes, sparsely dusted with grey. Tubercular pit indistinct, pseudosutural fovea concolourous with presutural scutum. Scutal lobes and scutellum brownish yellow, mediotergite yellow to brownish yellow. Pleuron yellow dorsally, pale yellow ventrally, sparsely dusted with greyish yellow. Wing (Fig. 17) semi-translucent, pale yellow, without darker areas except stigma. Stigma indistinct, brownish. Veins pale brown, yellowish at wing base and in costal area. Macrotrichiae more abundant in radial cells and cell m 1, also present in other marginal cells along postero-apical wing margin, few macrotrichiae present in cell cua at wing margin. Venation: Sc long, reaching slightly before branching point of Rs, sc-r ~ 3 × its own length from tip of Sc. Rs long, slightly arched at base. Free end of R 1 longitudinal, R 2 transverse, indistinct, 3.3 × its own length from tip of R 1, R 3, and R 4 slightly arched and diverging towards wing margin, cell r 3 with short stem. Cross-vein r-m distinct, at base of discal cell. Discal cell 1.8 × as long as wide. Cross-vein m-cu at middle of discal cell. Anal vein slightly arched at wing margin, ending beyond base of Rs. Anal angle widely rounded. Length of male halter 0.8–1.2 mm, of female 0.8–1.6 mm. Halter pale, knob slightly infuscate. Coxae and trochanters yellow to pale yellow. Femur and tibia yellow, tibia slightly infuscate at apex. Basal tarsomere pale brown, remaining tarsomeres dark brown. Male femur I: 3.6–4.3 mm long, II: 4.0– 4.8 mm, III: 3.9–5.0 mm, tibia I: 4.5–5.4 mm, II: 3.9–4.9 mm, III: 4.0– 5.2 mm, tarsus I: 4.6–5.5 mm, II: 4.2–5.0 mm, III: 3.3–4.2 mm. Female femur I: 3.3–4.0 mm long, II: 3.1–4.4 mm, III: 3.4–4.9 mm, tibia I: 3.9–4.4 mm, II: 3.0–4.0 mm, III: 3.2–4.6 mm, tarsus I: 3.6–4.1 mm, II: 3.2–5.0 mm, III: 3.0– 3.6 mm. Claw simple, without spines. Abdomen. Tergites brownish yellow, sternites yellow. Male terminalia (Figs 18, 19) yellow. Ninth tergite with two triangle-shaped lobes at the middle of posterior margin and V-shaped indentation between them. Gonocoxite elongate, distinctly wider at base, narrower beyond middle, without additional lobe. Outer gonostylus with long, narrow, slightly sinuous outer branch and small triangle-shaped lobe at base. Outer branch with sclerotised distal part and blackened apex, two small apical hook-shaped teeth curved medially. Inner gonostylus large, fleshy, setose, two-branched. Outer branch long and narrow, inner branch short, reaching to ~ 1 / 3 of outer branch. Aedeagus (Fig. 20) strongly curved at ~ 2 / 3 length, distal part at ~ 90 0 angle to basal part (clearly visible in lateral view). Paramere posteriorly short, narrow, rod-shaped with darkened distal part, reaching just slightly beyond base of gonocoxite (best visible in ventral view). Interbase with tip rounded. Ovipositor (Fig. 21) pale yellow. Cercus very long, narrow, distal part slightly raised upwards. Hypogynial valve long, wedge-shaped, pointed apex reaching slightly beyond middle of cercus. Spermatheca small, rounded. Elevation range. From the sea level to nearly 1700 m. Period of activity. From the end of April through late July. Habitat. Mountainous river margins covered with deciduous trees and shrubs. General distribution. Species was known only from Honshu island, Japan. Recorded from the Korean Peninsula for the first time.
