Antenna ( Fig. 1A ) brown, 1.3-1.8 mm long in male, 1.3-1.6 mm in female, reaching to about wing base if bent backwards. Scape elongate, slightly widening distally, pedicel 0.8 times as long as scape, pear-shaped. Flagellum 12-segmented, each flagellomere with distinct pale apical pedicels, basal segments oval, distal elongate, apical flagellomere 1.5 times as long as penultimate. Longest verticils 1.2 times as long as respective segments. Rostrum yellowish brown, semi-polished. Palpus brown.

Thorax: Yellow with brown stripes. Pronotum brown, yellowish laterally. Mesonotal prescutum yellow with three brown longitudinal stripes. Medial stripe wide frontally, turning narrow and indistinct at posterior margin of sclerite. Lateral stripe starts at middle of sclerite and gets wider posteriorly. Lateral margin of prescutum brownish. Scutal lobe brown, area separating lobes pale. Scutellum brown, mediotergite grayish yellow. Pleuron yellow with brown longitudinal stripe.

Wing ( Fig. 1B ): Length of male 5.6-6.8 mm, of female 4.6-7.1 mm. Brownish, costal and basal areas brighter. Stigma oval, brown.

Venation: Sc medium-long, Sc 1 reaching to about one third of Rs length. Sc 2 at tip of Sc 1. Rs medium-long, arcuate or angulate and short-spurred at base. Free end of R 1 short, nearly transverse, light and indistinct. R 2 at tip of R 1, sometimes also indistinct. R 3 and R 4 + 5 slightly arched, parallel to each other. Discal cell elongate, 1.75 times as long as wide. Basal deflection of CuA 1 at or close to branching point of M. Anal lobe widely rounded. Length of halter in both sexes 0.7-1.1 mm.

Distal tarsomeres dark brown. Male femur I: 4.5-5.0 mm long, II: 4.6-5.4 mm, III: 5.1-5.7 mm, tibiae I: 5.3-6.1 mm, II: 5.0- 5.7 mm, III: 5.3-6.1 mm, tarsus I: 6.0- 6.5 mm, II: 4.8-5.6 mm, III: 4.8-5.5 mm.

Claw with one subbasal spine ( Fig. 1C ).

Abdomen: Abdominal tergites with yellow base and dark brown distal half. Sternites slightly darker basally, than distally. Ninth tergite shorter than wider, with wide shallow emargination at posterior margin.

Genitalia: Male genitalia ( Fig. 1E ) yellow. Gonocoxite with three setose tubercles on mesal surface. Outer gonostylus long, narrow, gently curved, blackened, pointapexed. Inner gonostylus small, oval with very powerful, darkened and strongly arched rostral prolongation. Paramere wide at base, distal part rod-shaped, blunt-apexed. Penis long and narrow, nearly reaching middle of gonostylus, apex shallowly bifid. Ovipositor ( Fig. 1D ) brown. Tenth tergite elongate, yellow. Cercus long, narrow, distal part turned upwards. Hypovalva with black spot at base.

Elevation range in Korea: Sea level to slightly above 600 m.

Period of activity in Korea: Late June through early September.

Bionomics: Slopes of mountainous rivers covered by deciduous forest, abandoned gardens near small streams. Adults attracted to light.

Distribution: Species was known only from Hokkaido Island, Japan.
