Description. Male. Body small. Fastigium of vertex narrower than scape, apex obtuse, dorsal surface with a longitudinal furrow. Eyes comparatively bigger, subglobular. Pronotum subsellate, anterior margin slightly protruding, posterior margin obtusely rounded, metazona raised upwards, lateral lobes of pronotum triangular, with a tumid oval semitransparent area along posterior margin on both sides. Prosternum bispinose, apices obtusely rounded. All femora without spines on ventral surface. Procoxa with a long spine; genicular lobes of profemora semi-triangular, apices obtusely rounded; protibiae with 6 pairs of spines on ventral surface; tibial tympana slitshaped on internal and external sides. Apices of genicular lobes of mesofemora with a spine on internal side, mesotibiae with 6 pairs of spines on ventral surface. Apices of genicular lobes of postfemora with a spine on internal and external sides separately; posttibia with 20–21 spines on internal and external sides of dorsal surface separately, with a dorsal apical spur on external margin; posttibia, with 3–4 internal spines and 6–7 external spines on ventral surface, 2 pairs of apical spurs. Tegmina short, apices reaching the middle of second abdominal tergite, rectangular, apices truncate. Tenth abdominal tergite complicated, broad in base, slightly disc-like, submedian protruding afterwards angularly in lateral view, compressiform, ventral margin arc-shaped, apical half curved upwards, apical area subacute; ventral margin of tenth abdominal tergite fissured, rectangular, extending on both sides. Cerci hidden under tenth abdominal tergite, invisible. Subgenital plate broad in base, extending outwards, middle part protruding afterwards significantly, lamella-shaped, apex obtusely rounded, with long hairs. Styli on apices of inner margins of lateral lobes of subgenital plate, cylinder-shaped, long, apices obtusely rounded, with dense hairs.

Coloration. Body yellowish brown, frons green. Eyes brown, with some brown spots, lateral margin black. Lateral lobes of pronotum black, margins light colour. Tegmina with posterior margin yellowish brown, the middle black, anterior margin green. Middle area of abdominal tergites colourless, with a pair of longitudinal black stripes on lateral margins, ventral margin yellowish brown; most part of tenth abdominal tergite black, posterior process yellowish brown. Spines and apical spurs of all tibiae blackish brown. Dorsal margins of tibial tympana blackish brown.

Female. Unknown.

Type material. Holotype: male, Xinhua, Xinping, Yunnan, 29–30 July 2009, collected by Ji-Shan Xu and Jian- Xiong Zhang. Paratypes: 4 males, Xinhua, Xinping, Yunnan, 29–30 July 2009, collected by Ji-Shan Xu and Jian- Xiong Zhang.

Measurements (mm). Male: body: 9.4–9.5; pronotum: 2.5–2.8; tegmen: 0.9–1.2; postfemur: 8.5–8.7.

Remarks. This new species is allied to Conanalus axinus Shi, Wang & Fu, 2005 , but it is different from the latter in: male tenth abdominal tergite broad in base, slightly disc-like, submedian protruding afterwards angularly in lateral view, compressiform, ventral margin arc-shaped, apical half curved upwards, apical area subacute; ventral margin of tenth abdominal tergite fissured, rectangular, extending on both sides.

Distribution. China (Yunnan).

Etymology. This new specific name is derived from male tenth abdominal tergite.
