Redescription.

General body colouration pale yellow to whitish yellow. Body length of male 5.0– 6.9 mm, of female 5.2–8.7 mm. Wing length of male 6.1–7.1 mm, of female 5.4–7.1 mm.

Head. Brown, reddish along posterior margin, densely covered with pale grey pruinosity and sparse pale yellow setae. Antenna short, 0.9 mm long in male, hardly reaching frontal margin of prescutum if bent backwards, 0.7 mm long in female. Scape and pedicel reddish, flagellum 12 - segmented, pale yellow with somewhat greyish distal flagellomeres. Basal flagellomeres short, oval, just slightly longer than wider, distal flagellomeres elongate, length of apical segment slightly exceeds penultimate. Longest verticils approximately as long as respective flagellomeres. Rostrum dark brown, densely dusted with grey, palpus pale yellow, labellum pale greyish brown.

Thorax. Generally pale yellow. Pronotum whitish. Presutural scutum pale yellow without darker stripes. Tubercular pit missing, pseudosutural fovea indistinct. Scutal lobe pale, area between scutal lobes whitish. Scutellum and mediotergite pale. Pleuron yellow to reddish yellow with blurred whitish areas. Membrane surrounding prothoracic spiracle concolourous with rest of pleuron. Wing milky, subhyaline, strongly iridescent, patterned with brown spots, sexually dimorphic. Male wing (Fig. 29 View Figures 29–33 ) widened posteriorly at tip of anal vein, female wing (Fig. 30 View Figures 29–33 ) without such widening, widely rounded along posterior margin. Patterning includes completely darkened costal cell from wing base to slightly beyond Rs base, subcostal cell also darkened but with clear window before sc-r; all cross-veins and branching points surrounded by dark areas, small greyish dots distributed along longitudinal veins, veins R 4 and R 5 with or without small dots (different from D. ( E.) nebulipennis Alexander, 1936 which has at least one large spot in that area). Stigma indistinct. Veins brown or greyish brown, dark brown in darkened areas. Venation: Sc long, reaching to or slightly beyond level of supernumerary cross-vein in cell r 1, sc-r at ~ 2 / 3 between humeral vein and base of radial sector. Rs long, strongly arched or angulate and short spurred at base. Free end of R 1 distinctly shorter than R 2. Vein R 2 transverse, supernumerary cross-vein in cell r 1 beyond branching point of R 2 + 3 + 4. R 4 and R 5 straight and parallel to each other. Cell r 3 with short stem, cross-vein r-m distinct, discal cell large, 3.1–3.4 × as long as wide. Cell m 1 long, slightly longer than its stem in male, slightly shorter in female. Cross-vein m-cu beyond branching point of M. Vein CuP straight, A 1 slightly arched before wing margin. Anal angle widely rounded. Length of male halter 0.9–1.0 mm, of female 1.1 mm. Halter pale greyish, stem pale with whitish base, knob yellowish. Coxae from pale yellow in male to obscure yellow in female, fore coxa darker than posterior, mid-coxa darker at base. Femora whitish with narrowly and indistinctly infuscate apices. Tibiae and basitarsi whitish, second tarsomere slightly darkened distally, remaining tarsomeres brownish. Male femur I: 3.4–4.0 mm long, II: 3.6 mm, III: 3.5–4.8 mm, tibia I: 3.7–4.3 mm, II: 3.7 mm, III: 3.6–4.4 mm, tarsus I: 4.4–4.7 mm, II: 5.0– 5.6 mm, III: 4.4–4.6 mm. Female femur I: 3.9 mm long, II: 3.9–4.3 mm, III: 3.4–4.9 mm, tibia I: 4.1 mm, II: 4.0– 4.3 mm, III: 3.5–4.4 mm, tarsus I: 5.2 mm, II: 4.7–5.4 mm, III: 3.7–4.7 mm. Claw small and simple, without spines, dark brown.

Abdomen. Tergites weakly bicolorous, pale greyish brown with darker caudal margins, covered with sparse erect greyish setae. Basal sternite pale, second and third sternites pale with darkened posterior margins, remaining sternites greyish brown, paler at base. Sparse setae covering sternites pale. Female abdomen generally paler than that of male. Male terminalia (Figs 31 View Figures 29–33 , 32 View Figures 29–33 ) dark brown. Posterior margin of epandrium extended into triangle-shaped medial lobe, shape of which can vary slightly: narrower in specimens from Korea, wider in specimens from Mongolia. Postero-lateral corner of epandrium with long and narrow, spine-shaped lobe, reaching to ~ 2 / 3 of gonocoxite. Whole posterior margin of epandrium covered with sparse long setae. Gonocoxite elongate, nearly twice as long as wide, widest at middle. Interbase with narrow stem and ball-shaped tip. Outer gonostylus dark brown and looks like extension of gonocoxite, wide and fleshy, outer and distal margin covered with numerous small blackened spines, mesal margin with three long pale setae. Inner gonostylus elongate, pale, outer margin with low blunt bump at middle, basal part of inner gonostylus encircled by outer gonostylus, tip rounded with few fine setulae. Proctiger divided longitudinally by deep narrow medial incision. Aedeagus short, round-apexed. Paramere long, blade-shaped. Ninth sternite widely concave at middle of posterior margin. Ovipositor (Fig. 33 View Figures 29–33 ) dark brown with pale distal part of hypogynial valve. Cercus slightly arched, distal part raised upwards, blunt-apexed, hypogynial valve straight, blackish at base, narrowing distally, apex with short strong seta, dorsal margin with three long setae at approx. middle. Spermathecae two, small, subglobular.

Elevation range.

From sea level to nearly 2000 m.

Period of activity.

From early May through to middle of October.

Habitat.

Adults were found among dense grassy vegetation along margins of water bodies and in marshy forest openings in South Primorye ( Savchenko 1983), we found them flying along margins of small and medium-sized mountainous streams and rivers densely covered with trees and shrubs, in grassy vegetation surrounding springs and small pools in South Korea. Species is attracted to light.

General distribution.

Species was recorded from the eastern Kazakhstan, Honshu Island of Japan, and the Far East of Russia.

Remark.

Species recorded from the Korean Peninsula and Mongolia for the first time.
