Head: Dark brown, densely dusted with gray and covered with sparse short erect brown setae. Vertex without tubercle. Eyes widely separated in both sexes, distance between them at base of antennae approximately same as length of both basal antennomeres taken together. Antenna ( Fig. 10A ) dark brown, 1.7-1.8 mm long in male, nearly reaching wing base, if bent backward. Female antenna 1.0- 1.7 mm long. Scape dusted with gray, elongate, nearly cylindrical, twice as long as pedicel. Pedicel widened distally. Flagellomeres elongate, narrower towards apex of antenna, covered with dense whitish pubescence. Apical segment subequal in length to preceding. Verticils dark brown, longest twice as long as respective segments. Rostrum and palpus dark brown, labella brown.

Thorax: Cervical sclerites and pronotum dark brown dusted with gray. Mesonotal prescutum dark brown, dust- ed with gray, with four indistinct longitudinal stripes that are getting darker towards posterior margin of sclerite, medial and lateral stripe reaching each other. Tubercular pits indistinct at frontal margin of sclerite, pseudosutural fovea distinct polished black, surrounded by yellowish-brown area. Scutal lobe brown, dusted with gray, with indistinct darker spot at middle. Area between lobes brownish gray. Scutellum grayish brown. Mediotergite grayish brown, darker posteriorly. Pleuron brown, densely dusted with gray, katepisternum darkened ventrally. Wing ( Fig. 10B ) iridescent with brownish tinge, yellowish at base. Stigma distinct, dark brown, slightly elongate. Brownish spots at base of wing, along frontal margin, surrounding branching points of veins and cross-veins and at tips of all longitudinal veins along wing margin. Veins brownish, darker in darkened areas, yellowish at wing base. Venation: Sc long, reaching wing margin slightly before branching point of Rs, sc-r four- five times its own length before tip of Sc. Rs long, arched at base. Free end of R 1 short, slightly arched, R 2 indistinct, about its own length before tip of R 1, less than its own 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 m-cu. Cross-vein r-m distinct, slightly beyond 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 distinctly beyond base of Rs and before tip of anal vein. Anal vein long, slightly sinuous. Anal angle wide, posterior margin widely rounded. Halter pale yellow, knob same color as stem. Length of male and female halter similar, ranging from 0.8 to 1.0 mm. Frontal coxae brown, yellowish ventrally, remaining coxae obscure yellow, sparsely dusted with gray. Trochanters obscure yellow. Femur yellow, narrowly but distinctly dark brown at apex, but just indistinctly darkened in other. Tibia yellow with narrowly dark brown apex, darkening varies depending on specimen. Basal tarsomere yellowish basally, brown distally, remainder 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: 3.0- 4.5 mm long, II: 4.0- 4.3 mm, III: 4.0- 4.7 mm, tibia I: 4.4-4.5 mm, II: 4.5-4.8 mm, III: 4.0-5.0 mm, tarsus I: 4.2-4.4 mm, II: 3.8-4.4 mm, III: 3.2-3.5 mm.

Claw simple, without spines.

Abdomen: Tergites dark brown, dusted with gray, covered with sparse yellowish erect setae. Sternites yellow, pale yellow at base of abdomen, with wide dark brown lateral and posterior margins. Male terminalia ( Fig. 10C ) brownish yellow. Ninth tergite wider than longer, posterior margin widely concave at middle. Gonocoxite elongate, widened ventro-medially at base. Outer gonostylus sclerotised, blade-shaped, with two apical spines, sometimes partly worn or broken in older specimens. Inner gonostylus fleshy, elongate, setose. Paramere simple, elongate, stick-shaped. Aedeagus short and straight. Ovipositor ( Fig. 10D ) brownish-grayish yellow. Cercus long, narrow and slightly arched, blunt-apexed. Hypovalva long and straight, point-apexed, reaching to about middle of cercus.

Elevation in Korea: From sea level to more than 2100 m. Period of activity in Korea: Adults are active from early May through mid October.

Habitats: Small, clean streams and springs with mosscovered rocks surrounded by dense deciduous trees and shrubs in mountainous areas, sometimes around channels running through agricultural fields, marshy areas densely covered with willow shrubs. Species is attracted to light.
