(Figs. 16–20)
Diagnosis. Compound eyes dichoptic, upper division small, about 1/10 as large as lower division. Posterior margin of epandrium concaved medially, W-shaped, lateral margin slightly concaved medially; cercus bilobate, each lobe conical, round apically, with several long hairs.
Description. Male. Body length 4.0– 4.5 mm, wing length 5.5–6.0 mm, wing width 1.7–1.9 mm. Head uniformly dark brown. Ocellar triangle brown. Head mostly without hairs, except eyes with two long hairs along dorsal margin. Compound eyes dichoptic, boundary of upper division and lower division conspicuous; upper division about 1/10 as large as lower division, dark brown with pubescences; lower division dark brown with pubescences. Ocelli brick-red, prominent. Antenna longer than head width, scape and pedicel short, with several long hairs medially; first flagellomere slightly constricted basally, other flagellomeres cylindrical; antenna uniformly dark brown with short hairs. Proboscis dark brown with brown hairs. Palpus five-segmented, first segment short, segments 2–4 long, fifth segment slender and long, as long as the total length of segments 1–4; palpus mostly yellow, 5th segment yellow brown, with brown hairs.
Thoracic dorsum uniformly brown; pleuron mostly brown with yellow plaque; only scutellum with dense patches of hairs on anterior margin. Legs mostly yellow brown except coxae and trochanters yellow; legs with uniformly black hairs, tibiae without spurs. Wing (Fig. 17) subhyaline, veins brown. Sc rudimentary, not ending at base of Rs; Rs straight, a little longer than r-m; r-m straight. Base of halter yellow, knob brown with short brown hairs.
Abdominal tergites mostly brown, tergites 2–6 with narrow yellow brown band basally; sternites mostly yellow brown; hairs on abdomen dark brown. Male genitalia (Figs. 18–20): Posterior margin of epandrium concaved medially, W-shaped, lateral margin slightly concaved medially, with several long hairs; hypandrium slightly narrow basally, posteromedial margin concave; cercus bilobate, each lobe conical, round apically, with several long hairs; outer gonostylus swollen and slightly notched apically in lateral view, with uniformly hairs; inner gonocoxal lobe transparent, slender; paramere slender.
Female. Unknown
Material examined: 1♂, CHINA, Hebei, Pingquan, Guangtoushan, 1986. VII.3, 1200 m, Ding Yang; 11♂, Hebei, Xiaowutai, 2005. VII.1, Hui Dong; 2♂, Shanxi, Jiaocheng, Pangquangou, Changlicun, 2011. VII.10, Qifei Liu.
Distribution. China (Hebei; Shanxi).
Remarks. This new species is somewhat similar to B. yamasakii, but can be easily separated from the latter by the following features: the apical flagellomere is equal in length to the penultimate flagellomere; epandrium transverse, posterior margin concave medially, V-shaped; cercus bilobate, each lobe conical, round apically. In B. yamasakii, the apical flagellomere is 1.5 times the length of the penultimate, the epandrium is transverse with the posterior margin truncate, each lobe of the cercus is semicircular (Kitakami, 1950).
