Hemithyrsocera hemiptera sp. nov. (Figs 1–5) Material examined. Holotype ♂, Yuping, Pingbian, Yunnan, China, elev. 2000–2200 m, 21 May 2009, leg. Xianwei Liu et al. Diagnosis. This new species is similar to H. vittata, but differs in the shortened tegmina, the absence of hind wings, the shape of supra-anal plate and subgenital plate. Measurements (mm). Male, overall length including tegmina 10.5; pronotum length × width 3.8 × 2.5; tegmina length 3.0. Description. Male. Body small. Vertex with interocular space slightly narrower than space between antennal sockets. Pronotum nearly elliptical, median section is the widest and hind margin slightly convex. Tegmina curtate and extending to the third abdominal tergum. Hind wings absent. Spines of front femur is Type A 3. The length of first hind tarsus is approximately the sum of the others; pulvilli on 4 proximal tarsomeres, tarsal claws symmetrical and simple, arolia present. First abdominal tergum unspecialized; seventh abdominal tergum specialized, with setae medially. Supra-anal plate symmetrical, hind margin wide and rounded (Fig. 1). Subgenital plate asymmetrical, lateral margins slightly concave, hind margin convex with spines and setae, one large process arising between the styli, apex spined (Fig. 2). Left stylus larger with apical spines; right stylus smaller with setae. Hook-like phallomere (Fig. 3) long and slender, sclerotized portion small and preapical hook-like. Coloration. Body yellowish brown (Figs 4–5). Vertex dark brown. Ocellar spot pale yellow. Antennae dark brown. Pronotum dark brown with complete yellow border. Tegmina pale brown. Legs brown. Abdominal terga and sterna brown. Female. Unknown. Etymology. The specific name hemiptera refers to the short tegmina of the new species. Discussion. The new species is quite different from other species of the genus as its tegmina extending to the third abdominal tergum and the hind wings absent, while other species have the tegmina and the hind wings well developed. Except this, the species fits all features of the genus Hemithyrsocera. As a result, we temporarily treated the new species under the genus. Distribution. China (Yunnan).
