(Figs. 27–35)
Description. Male. Body length 6.8–7.2mm. Head. Eye bare; frons about 1.5–2.0 times the width of anterior ocellus, frontal vitta velvet black and as wide as fronto-orbital plate, interfrontal seta distinct, sometimes 2 pairs, without proclinate orbital setae, outer vertical setae fine, about 6 pairs of frontal setae on lower half of frons; fronto-orbital plate and parafacial black, covered with grey pruinosity, parafacial as wide as or wider than antennal postpedicel, antenna black, antennal postpedicel about 2.5 times as long as broad, arista ciliated, the longest hairs twice the width of basal diameter of arista, facial carina low, vibrissal angle situated behind frontal angle in profile, epistoma not prominent; 1 row of upcurved subvibrissal setulae, gena covered with grey pruinosity, genal height twice the width of parafacial, genal hairs black, median occipital sclerite bare, paracephalon with hairs; postocular setae extending to ventral surface, palpus a little shorter than prementum, prementum long and polished, 4.0 times as long as broad.
Thorax. Ground colour black and covered with grey pruinosity, scutum with 3 black vittae, and the median vitta nearly reaching scutoscutellar suture. Pre -acr trichoid in 2 rows, post -acr row also trichoid, only 1 pair of distinct setae before scutellum, dc 2+3, without outer posthumeral seta, ia 0+2, pra about 1.5 times length of posterior notopleural seta, often without anterior anepisternal seta, scutellum black and without spot, apical part of scutellum with mostly pale hairs on undersurface, notopleuron, basisternum of prosternum, median cavate of proepisternum, anepimeron, katepimeron and meron bare, anterior and posterior spiracles small and fuscous, katepisternal setae 1+2.
Wing. Base brown, veins fuscous, basicosta light brown, costal vein setulose only basally on ventral surface, costal spine short, basal node of vein R4+5 bare. Calypters light brown, the edge of calypters covered with long brown hairs, lower calypter about 3/5 the length of upper calypter, haltere yellow. Legs. Proximal 3/5 of fore femur, proximal 3/4 of mid and hind femur, and distal 3/4 of all tibiae yellow. The rest of the legs black, only proximal 1/2 of fore femur brown. Fore tibia with 1 submedial ad, 1 medial pv; mid femur with 3–4 pv on proximal half, mid tibia with 1 ad, 2 pd, 2 pv; hind femur with complete rows of sparse and long av and pv, hind tibia with 3–4 av, 4 ad, 3–4 pd, 3–4 median p, without apical pv. All tarsi longer than tibiae, claws short, pulvilli long.
Abdomen. Ground colour black, long-ovate and a little flat, with broad T-shaped spots medially on tergites 2–5, laterally covered with white pruinosity; marginal setae and lateral seta strong, tergite 6 bare, sternite 1 with hairs, sternite 5 swollen, inner part of lateral lobe of sternite 5 with 4–5 spiniform setae and its outer margin with long setal rows; apical process of cercal plate a little short and about 1/4 of the length of cercal plate, pregonite with 2 long setae, sclerotized plate in distiphallus of aedeagus rather small.
Female. Head. Frons about 1/3 width of head, frontal vitta dark red and about 2.5 times as wide as frontoorbital plate, 1 pair of proclinate orbital setae, 2 pairs of upper orbital setae, about 3 pairs of frontal setae, 1 pair of interfrontal setae, outer vertical setae distinct; lower half of fronto-orbital plate and parafacial covered with brownish yellow pruinosity, height of gena about 1.5 times the width of parafacial. Legs. Fore tibia with 2 ad and 2 pd on distal half; mid femur with 2 pv on proximal half, mid tibia often with 1 av, 1–2 ad; hind femur with 2–3 pv on basal half. Abdomen. Long-oviform, spermatheca oviform, other characters as in the male.
Type material. Holotype, ɗ, CHINA: Changpingguo, 3500–3600m, 102°00'– 102°58'E, 31°06'– 31°43'N, Rilong, Sichuan Province, 5.viii.2005, (Jia-yu Liu) (SYNU).
Paratypes, CHINA: 22ɗ, same data as holotype, (Ming-fu Wang) (SYNU); 7ɗ, 1Ψ, same data as holotype, (Liang Chang) (SYNU); 1ɗ, same data as holotype, (Hu Ao) (SYNU); 1ɗ, same data as holotype, (Jiayu Liu) (SYNU); 2ɗ, Rilong, 3300m, 102°00'– 102°58'E, 31°06'– 31°43'N, Sichuan Province, 6.viii.2005, (Ming-fu Wang) (SYNU); 4ɗ, Rilong, 3300m, 102°00'– 102°58'E, 31°06'– 31°43'N, Sichuan Province, 6.viii.2005, (Hu Ao) (SYNU); 8ɗ, 1Ψ, Mt. Xiling, Dayi, 2200m, 102°54'– 103°17'E, 30°35'– 30°49'N, Sichuan Province, 12.viii.2005, (Ming-fu Wang) (SYNU).
Remarks. The new species resembles B. flavibellula (Deng, 1995), but differs from it by the male genal height being twice the width of parafacial, epistoma not prominent, 1 row of upcurved subvibrissal setulae; pra about 1.5 times length of posterior notopleural seta, katepisternal setae 1+2; distal 2/5 of fore femur, distal 1/4 of mid and hind femur, and proximal 1/4 of all tibiae black, only proximal half of fore femur brown; male proximal part of cercal plate broad, apical process broad and short, ramus of surstyli long in posterior view and straight in lateral view, anterior margin of surstyli protruding anteriorly.
Etymology. The species name is derived from the Greek word platys, meaning broad and surstyla, meaning surstyli, referring to this species’ broad male surstyli.
Geographic distribution. China.
