(Figs. 12–15)
Diagnosis. Wing light brown, subhyaline; wing with obviously white net-like lines; Rs straight, as long as r-m; base of halter dark brown, apex of haltere black. Epandrium semicircular, lateral and posterior margin rounded, posterior margin slightly concaved medially; cercus transverse, bilobate, each lobe elliptical; outer gonostylus forming a broad semicircular lobe medially, apical part finger-like.
Description. Male. Body length 4.3 mm, wing length 4.5 mm, wing width 1.7 mm. Head uniformly dark brown. Ocellar triangle dark brown. Eyes with a row of several long hairs along dorsal margin; vertex with two bunches of long hairs. Compound eyes dichoptic, boundary of upper division and lower division conspicuous; upper division of eye about 1/2 as large as lower division; brick-red with pubescences; lower division black with pubescences. Ocelli large, light yellow, prominent. Antenna longer than head width; scape and pedicel short; flagellomeres 1–12 mostly subequal in length, twice longer than wide; antenna uniformly dark brown with short black hairs. Proboscis shorter than height of head, with short black hairs. Palpus five-segmented, first segment short, 2nd–4th segments long, fifth segment slender and long, as long as the total length of segments 1–4; palpus brown, with uniformly black hairs.
Thoracic dorsum uniformly dark brown; pleuron brown; thorax without hairs. Legs brown, hairs on legs black. Wing (Fig. 13) light brown, subhyaline; wing with obviously white net-like lines, veins brown. Sc rudimentary, not ending at base of Rs; Rs straight, as long as r-m; r-m straight. Base of halter dark brown, apex of halter black, with short black hairs.
Abdominal tergites mainly dark brown, tergites 2–6 with narrow yellow brown band basally, sternites dark brown; hairs on abdomen black. Male genitalia (Figs. 14–15): Epandrium semicircular, lateral and posterior margin rounded, posterior margin slightly concaved medially, with uniformly short hairs; hypandrium trapezoidal, posterior margin wavy, slightly concave medially, with short hairs laterally; cercus transverse, bilobate, each lobe elliptical, with dense patch of hairs apically; outer gonostylus forming a broad semicircular lobe medially, apical part finger-like, with uniformly hairs; inner gonostylus slender and curved; paramere transparent.
Female. Unknown.
Type material. HOLOTYPE: ♂, CHINA, Hainan, Ledong, Jianfenglingzhiwuyuan, 2007. X. 24, 800 m, Ding Yang; PARATYPE: 1♂, same data as holotype.
Distribution. China (Hainan).
Etymology. The specific name refers to the type locality.
Remarks. This species differs significantly from the other species on Hainan island, B. macropyga, in the hypandrium not forming a large keel and in the coloration of wings (light brown with obviously white net-like lines). The shape of the male genitalia of this species differs from that of other species of Chinese Blepharicera in the shape of the epandrium (posterior margin round) and cercus (narrow bridge separating two lobes). In other known species, both cercal lobes are near to each other (Kitakami 1937, 1950; Zwick 1990).
