Description. Male. Body very small. Vertex of head divided into conical tubercles. Legs elongate and slender; fore femora about 1.4–2.0 times as long as the pronotum, beneath unarmed, internal knee lobe with a small spine, genicular lobe with 1 elongate movable spur; fore tibiae beneath with 1 external spur, without internal spur. Mid femora with a long movable spur on the internal and genicular lobe, beneath unarmed; mid tibiae beneath with 1 internal spur, without external spur. Hind femora without spines beneath; hind tibiae above with 65–68 outer spines and 64–69 inter spines, arranged in groups, inner subapical spur of hind tibiae shorter than hind metatarsus. Hind metatarsus with bristles beneath and approaching apical part keeled beneath ( Fig. 1 ). Epiproct with nearly triangular apex ( Fig. 2 ). Male genitalia with dorsolateral lobes distinctly sclerotized, with acute apex ( Figs. 3–4 ).

Female. Subgential plate nearly round, triangular and apically acutely pointed ( Fig. 5 ). Ovipositor shorter than or almost equal to half the length of hind femur.

Coloration. Body yellowish brown and without distinct stripes. Hind femora with light stripes.

Material examined. Holotype, 3♂♂, 1♀, Gutian Mountain, Kaihua , Zhejiang, alt. 330–800m, 2012. X.14–16, collected by Liu Xian-Wei et al. ; paratype, 1♂, 1♀, same data as holotype ; 1♂, Gutian Mountain, Kaihua , Zhejiang, alt. 330–800m, 2012. IX.14–16, collected by Liu Xian-wei et al. ; 1♂, Tianmu Mountain , Zhejiang, alt. 350m, 2013. IV.25–26, collected by Zhu Wei-Bing et al. ; 1♂, Huang Mountain , Anhui, 2013. IV.25–26, collected by Zhu Wei-Bing et al ..

Distribution. China (Zhejiang, Anhui).

Discussion. This species is relatively similar to Gymnaetoides acutilobatus (Gorovhov, 2010) comb. nov., but differs from the latter in: epiphallus of male genitalia “H-shaped”, lateral corium of middle lobes of male genitalia rather short and far from apex.
