Redescription. Male. Body length 8.0– 11.8 mm. Wing length 8.8–13.5 mm.
Head yellowish brown to brown with grey pruinescence; vertex with dark longitudinal central line, anterior half of vertex greyish; antenna with scape and pedicel brown to dark brown, pedicel sometimes slightly yellowish, flagellomeres 1–2 orange-yellow, following flagellomeres slightly darkened toward antennal end; mouth parts including palpus dark brown.
Thorax with mesonotum yellowish brown to brown, darker at lateral margins, with strong grey pruinescence; when viewed dorsally, pruinescence indistinct on anterior and lateral margins of mesonotum; prescutum with four weak darker stripes, central pair more slender than lateral ones, extending to near anterior margin, lateral stripes extending from near level of prescutal pit to scutellum, narrowly interrupted obliquely on scutal lobes; interspace between scutal lobes near posterior ends with pair of brown areas; mediotergite brown; pleuron brown to dark brown, mottled with darker areas and strong grey pruinescence. Legs with coxae yellow to dark brown; trochanters yellow; femora, tibiae and tarsomeres 1–2 yellow to yellowish brown, succeeding tarsomeres gradually darkened distally; distal end of each femur with long brown band, 3–5 times as long as width of femur, this band sometimes weakened at extreme tip. Wing (Fig. 24) 3.5–3.8 times as long as wide, greyish subhyaline with brown markings, outlined with dark brown; markings interrupted transversely at basal 1/2 and 3/4 of wing, making three sections of markings, sometimes partly continuous; circular marking enclosing base of Rs with distinct marking inside; both sides of inner and outer ends of cell d with small greyish subhyaline areas; cell d usually with two or sometimes three subhyaline areas; spots at tips of veins near wing tip fused at bases with adjacent ones; variation of development of wing marking large in same locality. Halter entirely light yellow.
Abdomen brown, gradually darkened posteriorly, with strong grey pruinescence, denser along posterior margin of each segment; sternites paler than tergites, darkened along lateral margins. Male genitalia (Fig. 25) with tergite 9 produced into a pair of small rounded median lobes at posterior margin; sternite 9 with conical tubercle directing posteroventrally at center of posterior margin; gonostyli small, about 1/3 length of gonocoxite; interbase (Fig. 26) with rod straight and long, extending far beyond tip of aedeagus and reaching at distal end of gonocoxite, with small barb at apex; base of interbase much shorter than rod.
Female. Body length 11.0–15.0 mm. Wing length 10.3–14.1 mm. Generally resembling male except for terminalia.
Ovipositor with sternite 8 (Fig. 27) with linear apodeme on whole length laterally; when viewed ventrally, sternite 8 excluding hypogynial valve usually slightly longer than wide, with dark markings along linear apodeme, widened at base and around tip, but sometimes indistinct; furca (Fig. 28) blade-shaped, weakly widened near middle, pointed and bent dorsally at apex, ventral surface of furca longitudinally keeled at middle; sternite 10 (Fig. 29) with three projections at anterior and posterior ends, central ones larger and obscure.
Distribution. Japan (Hokkaido; Honshu; Shikoku; Kyushu) (Fig 45) and Russia (Far East).
