Female macroptera. Large body, bicoloured ( Fig. 55View FIGURES 55 – 66); head brown, thorax yellowish brown, but distinctly lighter than head; abdominal segments I –V yellow, VI –VII yellowish brown to brown, median areas faintly shaded, IX –X brown; antennal segments I –II and IV –VIII brown, II yellow at apex, III and base half of IV –VI yellow ( Fig. 14View FIGURES 13 – 28); all legs brown except yellow fore tibiae; fore wings slightly shaded.

Head almost 1.5 times as long as wide, slightly constricted at base, dorsal surface smooth with weak sculpture posteriorly; postocular setae well developed, longer than eye, pointed apically ( Fig. 9View FIGURES 7 – 12); cheeks with about 6 pairs of spinous setae; mouth-cone short and pointed, maxillary stylets wide apart, restricted to mouth-cone; antennae about 2.0 times as long as head, VIII narrowed to base, III and IV with 1+1 and 1+2 1 sense cones respectively ( Fig. 14View FIGURES 13 – 28). Pronotum smooth, 4 pairs of major setae well developed, pointed to blunt apically, am reduced to minute setae ( Fig. 9View FIGURES 7 – 12); notopleural sutures complete; basantral plates absent; mesopresternum complete, broadened at middle; metanotum smooth, median setae well-developed, pointed apically; metathoracic sternopleural sutures absent; fore femora enlarged, fore tarsal tooth large; fore wing constricted at middle, with 5 duplicated cilia, subbasal wing setae well developed, S1 slightly shorter than S2, S3 the longest, pointed apically ( Fig. 44View FIGURES 29 – 46). Pelta hat-shaped ( Fig. 24View FIGURES 13 – 28); abdominal tergites II –VII each with two pairs of wing retaining setae; tergite IX setae S1 as long as S2, S3 the longest, slightly longer than tube with apices pointed ( Fig. 53View FIGURES 47 – 54); tube slightly shorter than head, anal setae almost as long as tube ( Fig. 53View FIGURES 47 – 54).

Measurements (holotype female). Body length 2900. Head length 320, from anterior margin of eyes 290, width across eyes 210; eye length 120; antenna length 590, segments I –VIII length (width): 50(40), 60(35), 95(35), 100(30), 95(30), 80(25), 60(20), 45(15).

Male macroptera. Similar to female, but smaller body, length 2400; fore femora weakly enlarged, fore tarsal tooth smaller; tergite IX S2 short and stout, S1–S3 length 200, 75, 230.

Material studied. Holotype female, China, Hainan, Wenchang County, 11.iv.1958, leaves of bamboo, Xiangling Meng  ; paratypes: 22 females and 9 males with same data as holotype  , 1 female, 1 male, 4& 9.iv.1958, Xiangling Meng.

Etymology. This species is named in one Latin word, “ magnus  ”, based on large body.

Comments. The new species is similar to the Japanese B. lewisi (Bagnall)  in body shape, but they can be distinguished by the body colour and body setae. In the species described above the body is bicoloured and all setae are extremely pointed, whereas in lewisi  the body is uniformly brown to dark brown and major setae are blunt or expanded. This new species is also resembles fasciata  and bicoloripes  in the large body and head as well as elongate antennal segments, but these species can be distinguished by the above keẏ
