General coloration dark grayish brown. Female body length 10.0 mm, wing length 14.8 mm.

Head black, covered with gray pruinosity, which is more intense at eye margins. Semi­erect brown setae densier at eye margins and on ventral side. Anterior vertex very narrow. Eyes large, ventrally nearly reaching each other. Antenna 14­segmented. Scape long and wide, reaching to about tip of rostrum, dark reddish brown to blackish, covered with sparse gray pruinosity. Pedicel short, slightly widened distally, dark reddish brown with lighter base. Basal flagellomeres short, nearly rounded, dark brown to blackish, covered with gray pruinosity. Apical flagellomere wide at base and distinctly narrowed at distal end, nearly twice as long as preceding segment. Verticils approximately as long as respective segments. Short pubescence, covering segments whitish, densier on ventral side. Rostrum dark brown, semi­polished. Palpus dark brown, covered with erect dark brown setae. Mouth parts dark brown.

Thorax dorsally brownish gray. Cervical sclerites, pronotum and mesonotal prescutum semi­polished, dark brown, covered with sparse gray pruinosity. Prescutum with four polished blackish stripes. Central stripes separated by narrow gray witta. Gray pruinosity densier on lateral margins of sclerite. Scutal lobes dark brown, semi­polished separated by wide silvery gray area. Scutellum and mediotergite reddish brown, but covered with dense gray pruinosity. Pleura dark brown, semi­polished, covered with gray pruinosity, which is densier posteriorly. Katepisternum bears few long yellow setae. Wing ( Fig. 7A View Fig ) with brownish tinge. Stigma large, elongate and dark brown. Costal area yellowish. Dark areas surround cord, distal end of discal cell and cubital vein. Distal margin of wing darkened, small dark spots surround base of Rs and distal ends of anal veins. Veins brown. Venation: Sc 1 reaching wing margin slightly before branching point of Rs, Sc 2 slightly before Sc 1 tip. Rs slightly arched at base. Both branches of Rs long, parallel to each other and slightly turned backwards before wing margin. Vein R 2 twice its own length before R 1 tip. Cross­vein r­m distinct, at base of discal cell. Discal cell elongate, 2.4 times as long as wide. Basal deflection of CuA 1 slightly beyond branching point of M. A 1 nearly straight, A 2 slightly sinuous. Anal angle medium­sized, posterior margin widely rounded. Length of female halter 2.05 mm. Stem of halter pale, base light brown, knob brownis distally. Coxae brown with yellowish distal part. Trochanter brownish yellow, distal margin narrowly blackened. Femur yellow at base, turning brown towards distal end. Tibia and tarsus brown. Female femur I: 8.5 mm long, II: 9.2 mm, III: 9.8 mm; tibiae I: 10.4 mm, II: 10.0 mm, III: 11.0 mm; tarsus I: 11.7 mm, II: 10.0 mm long. Claw with three additional spines.

Abdomen dark brown. Two basal sternites of female abdomen each with large obscure­yellow basal spot. Tergites and sternites covered with semi­erect scarce, whitish setae. Male genitalia (redescription based on specimens from Lithuania) same color as abdomen. Ninth tergite simple, posterior margin with small median emargination. Gonocoxite slightly elongate, with large setose ventro­mesal lobe. Outer gonostylus narrow, sclerotised and hook­shaped. Inner gonostylus large, fleshy and setose, bearing large elongate rostral prolongation armed with erect spine at middle of posterior margin. Elongate lobe with apical pencil of setae starts beyond base of rostral prolongation. Paramere distinctly narrowed towards distal end, acute­apexed. Penis simple, elongate with bifid apex. Ovipositor ( Fig. 8E View Fig ) with black tenth tergite and base of hypovalvae. Cercus polished brown to yellowish brown, nearly straight, with subapical bump. Hypovalvae long, reaching to about middle of cercus, distal end slightly enlarged and smoothly serrated.

Elevation range in Korea. Single female was captured nearly at 1920 m altitude in North Korea.

Period of activity. Single female was captured in middle of August in North Korea.

Habitats. The species was collected by the author in dense mixed forests, on river slopes covered with old deciduous trees, in marshy areas covered by forests in Eastern and Western Palaearctic Regions. The species is attracted to light. According to Savchenko (1985), larvae are developing in dead wood of deciduous trees.

General distribution. The species is widely distributed in Palaearctic Region.
