( Fig. 4, Map 1)

Type material. Holotype. ♂, Nanling, Ruyuan, Guangdong, 27 July, 2011, coll. Jian-Feng Wang.

Male. Body small, stouter. Head short and stout, fastigium frontis slightly inclined. Fastigium verticis conical, apex obtuse, with a longitudinal sulcus in midline. Eyes oval, protruding forwards. Apical segment of maxillary palpi slightly longer than subapical one, apex faintly swollen.

Pronotum elongate, reaching middle area of third abdominal tergite, anterior margin straight, posterior margin obtusely rounded, anterior and middle transverse sulci indistinct, posterior transverse sulcus distinct, metanoza slightly raised; posterior margin of paranota slightly broadened, humeral sinus absent.

Procoxa with a spine, all femora without spines on ventral margin, protibiae with 4 inner spines and 3 outer spines on ventral margin, and a pair of ventral apical spurs; tibial tympana open on both sides. Mesotibiae with 2 spines on inner side and 3–4 spines on outer side of ventral margin, and a pair of ventral apical spurs. Postfemora with genicular lobes obtuse, posttibiae with 16–18 spines on inner and outer sides of dorsal margin separately, and a pair of dorsal apical spurs and a pair of ventral apical spurs.

Tegmina short, not reaching posterior margin of pronotum, concealed under pronotum. Hind wings absent.

Tenth abdominal tergite broader, posterior margin with an arch-shaped notch, the lateral margins triangular prominent, apices slightly obtuse. Epiproct absent. Cerci longer, moderately curved upwards; middle area slightly broadened, apical area narrow, with a short obtuse tooth. Genitalia invissible. Subgenital plate with basal area broad, the centre triangularly concave; apical area slightly narrow, posterior margin with an obtuse triangle notch. Styli stout and short on apices of the lateral margins.

Body light yellowish brown, it may be green alive. Eyes brown. Disc of pronotum with a broad longitudinal light brown stripe, the lateral edges parallel, the outer margin with a separate longitudinal yellow stripe. Spines on dorsal margin of posttibiae and apical spurs with apices brown; apices of claws brown. Apices of cerci light brown.

Female. Unknown.

Measurements (mm). Body: ♂ 9.0; pronotum: ♂ 4.0; postfemora: ♂ 6.5.

Discussion. The new species is allied to Pseudocosmetura multicolora ( Shi & Du, 2006) , but it differs from the latter in: male tenth abdominal tergite broader, posterior margin with an arch-shaped concavity, the lateral margins triangularly prominent; cerci with middle area slightly broadened; body unicolorous.

Etymology. The name of the new species is derived from the type locality Nanling.

Distribution. China (Guangdong).
