Description

Male. Body length (excluding antennae): 5.9-7.4 mm; wing length: 5.0-6.0 mm. Head: Black and subshining; compound eyes densely covered with pale yellow hairs; occiput and vertex with pale recumbent hairs; postocular areas towards lower margin of eye slightly pale pollinose; face black pilose; lower frons with short black hairs; antennae short, apex of pedicel and inner surface of flagellomeres 2-6 tinged with pale yellow; flagellum 1.1-1.2 times as long as scape and pedicel combined; flagellomeres 3-6 swollen, about 1.5-1.6 times wider than pedicel (Fig. 4 View Figure 4 C). Thorax: Metallic green, scutum tomentose with pale yellow hairs; postpronotal lobe tinged with yellow; central part of anepisternum, katepisternum, except upper part and meron nearly bare. Legs: Mostly yellowish-brown, but the following parts tinged dark brown: fore and hind coxa, except apex, apical portion of hind femur, except extreme apex, hind tibia, except base, apices of tarsomeres 1 (but hind one slightly pale), and tarsomeres 2-5; hind tarsomere 1 about 2.4-2.6 times wider than hind tibia (Fig. 4 View Figure 4 A). Wings: Tinged with yellowish-brown; base of M1 and M2 convergent (Fig. 4 View Figure 4 E). Abdomen: Dark brown to black, lateral margin of tergites with conspicuously long pale yellow hairs; sterna wholly densely covered with recumbent pale yellow hairs; epandrium long, median margin quite concave, anterior margin semicircular; long surstyli inserted posterolaterally, strongly curved inwards; cerci nearly parallel-sided and straight; proctiger narrow and triangular (Fig. 4 View Figure 4 G); gonocoxite longer than wide, median projection incised rather than protruding, subquadrate; gonostyli clearly bent inwards; phallus comparatively thick, bifurcate; lobes bent and with diverging apices, three dorsal processes present (Fig. 4 View Figure 4 F, H).

Female. Similar to males, but differing as follows: Body length (excluding antennae): 5.0-6.2 mm; wing length: 4.4-5.8 mm. Head: Hairs on compound eyes relatively shorter and fewer than in males; occiput properly visible in anterior view; inner surface of flagellum, except apex tinged with brown to reddish-brown; flagellum nearly 1.3-1.5 times as long as scape and pedicel combined (Fig. 4 View Figure 4 D). Thorax: Hairs on side of scutum shorter than in males. Legs: Distal part of hind tibia paler rather than dark brown; hind tarsomere 1 less swollen than in males (Fig. 4 View Figure 4 B). Abdomen: Hairs on lateral margin of tergites shorter than in males.

Diagnosis

This species can be distinguished from other congeners by the following key diagnostic characters: flagellum about 1.5 to 2 times as long as scape (Fig. 4 View Figure 4 C), hind tarsomere 1 about 2.5 times wider than hind tibia (Fig. 4 View Figure 4 A) (males); flagellomere 8 less than 2 times as long as wide (Fig. 4 View Figure 4 D) (females). This species is particularly similar to the Japanese species, B. nebulosa Nagatomi and Tanaka, 1972, but the latter species has characteristics as follows: flagellum about 2.4 times as long as scape, hind tarsomere 1 as wide as hind tibia (males); flagellomere 8 more than 2 times as long as wide ( Nagatomi and Tanaka 1972:112).

Distribution

Korea (new record: Gangwon-do, Gyeongsangbuk-do, Daegu-si), China (Hubei, Sichuan), Japan (Hokkaido, Honshu, Shikoku, Kyushu), Russia (Far East: Siberia) and Taiwan.
