Head: Dark brown, densely dusted with gray and covered with sparse short erect setae. Vertex without tubercle. Eyes widely separated in both sexes, distance between them at base of antennae slightly exceeds length of both basal antennomeres taken together. Antenna ( Fig. 12A ) brown with yellow base of basal flagellomere and dark brown distal flagellomeres, 1.8-2.5 mm long in male, extending to base of abdomen, if bent backward, antenna of female 1.7-1.8 mm long. Scape dark brown, elongate, nearly cylindrical, twice as long as pedicel. Pedicel brown, widened distally. Flagellomeres elongate, narrow- er towards apex of antenna, densely covered with whitish pubescence. Apical segment subequal to preceding. Verticils dark brown, not reaching length of respective segments. Rostrum, palpus and mouth parts dark brown dusted with gray.

Thorax: Cervical sclerites and pronotum dark brown densely dusted with gray. Mesonotal prescutum dark brown, dusted with gray, with four indistinct longitudinal stripes that are getting darker towards posterior margin of sclerite, medial pair narrowly separated with gray. Tubercular pits indistinct at frontal margin of sclerite, pseudosutural fovea distinct polished black. Scutal lobe grayish dark brown because of dense pruinosity. Area between lobes with sparser pruinosity, semi-polished. Scutellum with indistinctly reddish brown posterior margin. Mediotergite brown with dense gray pruinosity, darker along middle. Pleuron uniformly dark brown covered with dense brownish-gray pruinosity. Wing ( Fig. 12B ) iridescent with brownish tinge, yellowish at base. Stigma distinct, dark brown, elongate. Brownish spots surrounding branching points of veins and cross-veins. Veins light brown, yellowish at wing base. Venation: Sc long, reaching wing margin nearly at branching point of Rs, sc-r about three times its own length before tip of Sc. Rs long, slightly arched, sometimes angulate and short-spurred at base. Free end of R 1 short and oblique, R 2 indistinct, about three times its own length before tip of R 1, far beyond branching point of R 2 + 3 and R 4. R 3 and R 4 diverging, cell r 3 with long stem, which is approximately as long as m-cu. Cross-vein r-m distinct, at base of discal cell. Discal cell twice as long as wide. Cross-vein m-cu slightly before middle of discal cell. Additional cross-vein in cell bm beyond apex of anal vein. Anal vein long, distinctly arched apically, reaching wing margin at the level between base of Rs and additional cross-vein in cell bm. Anal angle long and narrow, widely rounded. Halter pale brownish yellow. Length of male halter 0.9-1.3 mm, that of female 1.1-1.3 mm long. Coxae yellow, brownish at base, more intensely on frontal pair. Trochanters yellow. Femur yellow, narrowly dark brown at apex. Tibia brownish yellow with narrowly dark brown apex. Basal tarsomere brown with yellowish base, remainder of tarsus dark brown. Tibia of fore leg with single apical spur, tibiae of middle and hind pairs of legs with two apical spurs each. Male femur I: 4.3-4.8 mm long, II: 4.5-5.0 mm, III: 5.5-5.7 mm, tibia I: 4.5-5.8 mm, II: 5.5-6.0 mm, III: 5.3- 6.0 mm, tarsus I: 3.0- 5.5 mm, II: 6.1-6.2 mm, III: 4.5-5.2 mm. Female femur I: 4.5-4.6 mm long, II: 4.5-4.6 mm, III: 4.5-5.5 mm, tibia I: 4.7-5.5 mm, II: 4.3-4.5 mm, III: 5.0- 5.7 mm, tarsus I: 4.7-5.4 mm, II: 4.2-4.5 mm, III: 3.8-4.3 mm. Claw simple, without spines.

Abdomen: Abdominal segments semi-polished, covered with sparse whitish erect setae. Tergites reddish brown at base and along middle, widely dark brown laterally and posteriorly in male. Female tergites uniformly dark brown. Sternites dark brown, narrowly grayish along posterior margin, marked with yellowish at base of abdomen. Male terminalia ( Fig. 12C ) dark brown. Ninth tergite rectangular, wider than longer, posterior margin nearly straight, setose at middle. Gonocoxite elongate with large rounded ventro-mesal bump at base. Outer gonostylus elongate, sclerotised, serrated along outer margin, widened distally, apex claw-shaped. Inner gonostylus long and narrow, fleshy and setose. Paramere strongly arched. Aedeagus short and straight. Ovipositor ( Fig. 12D ) dark brown at base, turning yellowish towards apex. Cercus long, narrow and slightly arched, blunt-apexed. Hypovalva long and straight, point-apexed, reaching two-thirds of cercus length.

Elevation in Korea: From 40 to more than 1200 m.

Period of activity in Korea: Early May to June.

Habitats: Unknown in Korea, adults are active among grassy vegetation along streams and rivulets in the forests, near canals and holes filled with water in the Russian Far East close to the border with North Korea, sanctuary Kedrovaya Padj ( Savchenko, 1983).

General distribution: North Korea, Russian Far East.
