( Figs 10View FIGURES 7 – 12, 17, 25View FIGURES 13 – 28, 38, 45View FIGURES 29 – 46, 54View FIGURES 47 – 54, 62View FIGURES 55 – 66)

Female macroptera. Small body, bicoloured ( Fig. 62View FIGURES 55 – 66); head brown, but thorax yellow with sides shaded; abdominal segments I –VIII yellow, median area of III –VII faintly shaded, IX yellowish brown and tube brown ( Fig. 17View FIGURES 13 – 28); antennal segments I –II and IV –VIII brown, II at apex, III and base of IV –VI yellow; all legs yellow; wings slightly shaded.

Head almost as long as wide, dorsal surface smooth with weak sculptures posteriorly; postocular setae well developed, but shorter than eye, pointed apically ( Fig. 10View FIGURES 7 – 12); cheeks weakly rounded; mouth-cone short and pointed, maxillary stylets wide apart, restricted to mouth-cone; antennae about 1.7 times as long as head, segment VIII constricted at base, III and IV with 1+1 and 1+2 1 sense cones respectively ( Fig. 17View FIGURES 13 – 28). Pronotum smooth, 4 pairs of major setae well developed, pointed apically but the longest epim expanded apically, am reduced to minute setae ( Fig. 10View FIGURES 7 – 12); notopleural sutures complete; basantral plates weakly present, membranous; mesopresternum complete, narrowed at middle; metanotum with reticulate sculpture, median setae well-developed, pointed apically; metathoracic sternopleural sutures absent; forelegs normal, fore tarsal tooth absent; fore wing slightly constricted at middle, with 4 duplicated cilia, subbasal wing setae well developed, S1 almost as long as S2, expanded apically, S3 the longest, pointed apically ( Fig. 45View FIGURES 29 – 46). Pelta hat-shaped ( Fig. 38View FIGURES 29 – 46); abdominal tergites II –VII each with two pairs of wing retaining setae; tergite IX setae S1 as long as S2, S3 the longest, shorter than tube with apices pointed ( Fig. 54View FIGURES 47 – 54); tube slightly shorter than head, anal setae about 2.0 times as long as tube ( Fig. 54View FIGURES 47 – 54).

Measurements (holotype female). Body length 1900. Head length 210, from anterior margin of eyes 190, width across eyes 190; eye length 80; antenna length 350, segments I –VIII length (width): 30(35), 45(30), 50(30), 55(30), 50(25), 50(25), 40(20), 30(10). Pronotum length 140, width across median part 200; length of major setae: aa 10, am 5, ml 15, pm 5, pa 25, epim 30; fore femur width 110; fore wing length 730, subbasal setae S1–S3 length: 30, 30, 25. Pelta length 55, width at base 75, width at apex 40; tergite IX length 60, S1–S3 length 70, 75, 85; tube length 100, width at base 60, at apex 30; anal setae length 210.

Male. Unknown.

Material studied. Holotype female, China, Yunnan, Mengla County, 20.xi.1988, dead leaves of bamboo, Yun-fa Han  ; paratypes: 2 females with same data as holotype  .

Etymology. This species is named in two Latin words, “ longus ” and “ seta ”, based on the long anal setae.

Comments. This new species is somewhat similar to exastis  , but they can be distinguished by the body colour of pronotum and abdominal segments (in longisetis  the pronotum is obvious lighter than the brown head ( Fig. 62View FIGURES 55 – 66) and abdominal segments I –VIII yellow, in exastis  the pronotum is concolorous with the head and only abdominal segments I –VI yellow). The species also differs from exastis  in the anal setae about 2.0 times longer than the tube ( Fig. 54View FIGURES 47 – 54), whereas in exastis  the anal setae are slighter shorter than the tube.
