Redescription. Male. Head: eye bridge 3–4 facets wide. Antenna rough and brown; 4th flagellomere ( Fig. 5 E) about 2.0–2.5X as long as wide, with unicolored distinct neck, setae 2/3–3/ 4X as long as width of neck. Maxillary palpus ( Fig. 5 D) three-segmented, basal segment with 3–5 setae and a patch of sensilla, sensillae fine; third segment about 1.5X as long as second.

Thorax ( Fig. 5 G): dark, with coarse, long and dark setae. Posterior pronotum with setae. Scutum with sparse dark setae. Scutellum with 2–3 long and strong lateral setae. Wing ( Fig. 5 C) pale brown; posterior veins and wing membrane clearly without macrotrichia; stem of M as long as M-fork; x = 0.8–1.0X length of y, both bare; stem of CuA = 1/ 3X length of x; vein R1 = 4/ 5X length of R; R4+5 with macrotrichia dorsally and apicoventrally; vein C = 3/ 4X length of w. Halter short stemmed and dark brown. Leg pale yellow; apex of foretibia with dense group of setae ( Fig. 5 F); claws untoothed.

Abdomen: genitalia ( Fig. 5 A) about 1.5X wider than high and without basal lobe or ventral group of setae. Gonostylus ( Fig. 5 B) narrow, about twice as long as wide with strong apical spines; apex with strong and long tooth and three spines. Tegmen wider than high and flattened apically with very short and fine teeth; with heartshaped overlapping structure. Aedeagus short and thick.

Body length: 2.5–2.8 mm.

Female. Unknown.

Material examined. KOREA: Gangwon-do, Yangyang-gun, Seo-myeon, Osaek-ri, Mt. Seorak, Osaek fountain, yellow pan trap, 28.vi.2002, leg. H. Lee (2♂).

Habitats. Adult specimens have been collected in peat bogs and along stream shores ( Mohrig et al. 1992).

Distribution. Previously known from Austria, Germany, Latvia, Korea, and Slovakia ( Mohrig et al. 1985; Mohrig et al. 1992; Röschmann & Mohrig 1993; Heller & Menzel 2013). Also known from Russia Far East, Primorsk region, Kedrovaya Pad (1 male in SDEI; unpublished record).

Remarks. This species easily recognized by its relatively long legs, the shape of the maxillary palpus, and the strong apical spines on the gonostylus.
