Sinothaumaspis damingshanicus Wang, Liu, Li sp. nov.

( Figs. 1–8 )

Holotype ♂, Paratype 11♂ 22♀, Daming Mountain, Wuming County, Guangxi province, alt. 1250m, 2013. VII.19– 25, leg. LIU Xian-We et al. .

Description. Male. Fastigium of vertex conical, apically blunt and dorsally furrowed. Head hypognathous, last segment of maxillary palp approximately equal to the preceding. Paranota of pronotum low, humeral sinus absent. Thoracic auditory spiracle totally exposed. Tegmina short, too transparent to notice while alive, hind margin pointedly rounded and exceeding the terminal of pronotum, hind wings degraded. Fore tibiae spines of type 4, 4 (1, 1) armed on either margin of ventral surface, 5–6 outer and 4 inner spines on ventral margin of each mid tibia, hind tibiae with 28 – 30 dorsal teeth each margin above and 2 pairs of apical spurs. Posterior margin of abdominal tergite 10 bearing a conical middle process ( Figs 4, 6 ). Cerci robust, near cylindrical, a pair of processes occur on inner base, of which lower one acute at terminal; apex with bunch of seta ( Fig. 4 ). Posterior half of subgenital plate distinctly narrower than another, hind margin truncate , styli long, genitalia entirely membranous.

Female. Cerci short and thin, conical, subgenital plate inverted trapezoidal ( Fig. 7 ). Ovipositor short, upcurved, dorsal margin denticulate at middle one third. ventral valve without apical hook ( Fig. 8 ).

Coloration. Generally peak green of body, legs even lighter, transparent somewhat. Patches and stripes are bright yellow: paired paralleled stripes on dorsum of pronotum, each dorsum of abdomen tergite with a pair of patches. Eyes are also bright yellow. Antenna and spines of hind tibiae brownish.

Diagnosis. General appearance of this new species is similar to Thaumaspis , but characterized by not strongly oblique face, male 10th abdominal tergite with a simple pointed conical projection at middle of hind margin ( Fig. 4 ); female ovipositor denticulate on dorsal margin.

Measurements. Lengths in millimeter: body ♂9.0–10.0, ♀10.0–11.0; pronotum ♂3.9–4.2, ♀4.0–4.6; tegmina ♂2.5–2.8, ♀2.5–2.7; hind femora ♂9.5–10.5, ♀10.0–11.0; ovipositor ♀6.5–7.0.
