Head: Dark brown, densely dusted with gray and covered with sparse short erect brownish setae. Vertex without tubercle, but with darkening fronto-dorsally. Eyes widely separated in both sexes, distance between them at base of antennae slightly exceeds length of both basal antennomeres taken together. Antenna ( Fig. 9B ) 1.0- 1.2 mm long in male, reaching to wing base, if bent backward. Antenna of female 1.0- 1.2 mm long. Scape dark brown densely dusted with gray, elongate, nearly cylindrical, twice as long as pedicel. Pedicel brown, widened distally. Flagellomeres elongate, narrower towards apex of antenna, covered with whitish pubescence. Basal flagellomeres brownish yellow, distal brown to grayish brown. Apical segment subequal in length to preceding. Verticils dark brown, more than twice as long as respective segments. Rostrum, palpus, and mouth parts dark brown.

Thorax: Cervical sclerites and pronotum dark brown densely dusted with gray. Mesonotal prescutum dark brown dorsally brown laterally, dusted with gray, with four indistinct longitudinal stripes that are getting darker towards posterior margin of sclerite, medial pair narrowly separated with gray along middle, both stripes coming together posteriorly. Tubercular pits indistinct at frontal margin of sclerite, pseudosutural fovea distinct polished brown to dark brown. Scutal lobe grayish brown because of dense pruinosity with indistinct darker spot at middle. Area between lobes grayish brown, polished brown frontally. Scutellum grayish brown with few erect yellowish setae posteriorly. Mediotergite grayish brown. Pleuron uniformly brown covered with dense brownish-gray pruinosity. Wing ( Fig. 9A ) iridescent with grayish tinge, yellowish at base. Stigma distinct, dark brown, slightly elongate. Brownish spots at base of wing, surrounding branching points of veins and cross-veins and at tips of all longitudinal veins along wing margin. Veins brown in darkened areas, pale in light areas, yellowish at wing base. Venation: Sc long, reaching wing margin at branching point of Rs, sc-r about three times its length before tip of Sc. Rs long, angulate and short-spurred at base. Free end of R 1 short and oblique, R 2 indistinct, about twice its length before tip of R 1, less than its length 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 discal cell. Cross-vein r-m distinct, slightly beyond base of discal cell. Discal cell 2.8 times as long as wide. Cross-vein m-cu at about one-third of discal cell. Additional cross-vein in cell bm slightly before base of Rs and distinctly before tip of anal vein. Anal vein long, slightly sinuous. Anal angle wide. Halter yellow, knob same color as stem. Length of male halter 0.8-1.1 mm, that of female 1.0- 1.1 mm. Coxae light brown, sparsely dusted with gray. Trochanters yellow to yellowish brown. Femur pale grayish yellow, narrowly but distinctly dark brown at apex. Tibia pale yellow with narrowly dark brown apex. Basal tarsomere pale yellow with darkened distal part, remain- der of tarsus brown to dark brown. Tibia of foreleg with single apical spur, tibiae of middle and hind pairs of legs with two apical spurs each. Male femur I: 4.0- 4.3 mm long, II: 4.4-4.5 mm, III: 4.0- 5.5 mm, tibia I: 5.0- 5.1 mm, II: 4.2-4.5 mm, III: 4.5-5.5 mm, tarsus I: 4.0- 4.8 mm, II: 3.7-4.0 mm, III: 3.5-4.0 mm. Female femur I: 4.0- 4.5 mm long, II: 4.5-4.7 mm, III: 4.5-5.0 mm, tibia I: 5.0- 5.2 mm, II: 4.5-4.7 mm, III: 5.2-5.5 mm, tarsus I: 4.4-4.7 mm, II: 4.2-4.6 mm, III: 4.0- 4.2 mm. Claw simple, without spines.

Abdomen: Abdominal segments brown, dusted with gray, covered with sparse yellowish erect setae. Tergites widely dark brown along posterior margin. Basal segments of female abdomen with yellowish markings at base of tergites and sternites. Male terminalia ( Fig. 9C ) dark brown. Ninth tergite wider than longer, posterior margin widely concave at middle. Gonocoxite elongate with large rounded ventro-mesal bump at base. Outer gonostylus elongate, sclerotised, finely serrated along out- er margin, with single claw-shaped apical lobule. Inner gonostylus long and narrow, fleshy and setose. Paramere club-shaped. Aedeagus short and straight. Ovipositor ( Fig. 9D ) brownish yellow. Cercus long, narrow and slightly arched, blunt-apexed. Hypovalva long and straight, point-apexed, reaching before middle of cercus.

Elevation in Korea: From 300 to more than 1800 m.

Period of activity in Korea: From late June-late August. Habitats: Unknown in Korea. Adults are active in affluent alder and willow groves and in moist mixed and coniferous forests along streams in Kurile Islands, Russia ( Savchenko and Krivolutskaya, 1976).

General distribution: North Korea, Eastern part of Russia including Kurile and Sakhalin Islands.
