Homonemobius curifolis Zhang, Wang & Liu sp. nov.

( Figs. 4–5 , 13–15 )

Type material. Holotype: ♂, CHINA, Yunnan, Lincang , Mt. wulao, 9–10.VII.2009, leg. Jishan Xu, Jianxiong Zhang. Paratype: 1♀: same data the holotype.

Diagnosis. This new species is similar to Homonemobius nigru s Li, He & Liu, 2010, but differs from the latter by the lateral lobes of epiphallus distinctly bending inwards; tegmina rather long; all legs almost yellowish brown.

Description. Male ( Fig. 4 ). Body small-sized and pubescent. Head as wide as the width of anterior margin of pronotum, occiput convex, frontal rostrum narrow, almost equal to the width of scapus; apical joint of maxillary palpi longer than 2 nd and 3 rd joint, shorter than 2 nd and 3 rd joint combined; ocelli round, and arranged in an inverted triangle. Pronotum slightly transverse, with more pubescent, with a longitudinal groove on median part; anterior and posterior margins almost straight, anterior margin as wide as posterior margin. Tegmina extending to base of the 6 th abdominal tergite; dorsal field with 5 longitudinal veins, lateral field with 4 subcostal veinlets. Fore tibiae without tympanum; hind tibiae with 4 external dorsal spines and 3 internal dorsal spines, apex with 6 spurs.

Supra anal plate rather short. Subgenital plate narrowed posteriorly, nearly coniform. Genitalia ( Figs. 13–15 ): epiphallus rather short, distinctly transverse; lateral lobes of epiphallus bent inwards, acute at apex; ectoparameres distinctly widened, and obviously longer than epiphallus.

Female ( Fig. 5 ). Body very similar to that of male. Tegmina rather short, dorsal field with 4 longitudinal veins, lateral field with 8 subcostal veinlets. Hind tibiae with 3 pairs of dorsal spines. Ovipositor rather short, about the same length as the hind femur.

Coloration. Body black. Head with 2 long and 2 short yellow longitudinal stripes in occiput. Pronotum with yellow margin, with few spots in the middle. Tegmina with yellow spots in the base. All legs almost yellowish brown.

Measurements (mm). Male: body length 6.0, pronotum 1.1, hind femur 4.1. Female: body length 6.5, pronotum 1.2, hind femur 4.5, ovipositor 4.0.

Distribution. China (Yunnan).

Etymology. The specific name is derived from Latin curv and foli, a reference to lateral lobes of epiphallus bent inwards.
