Fig. 2

Description. Male Body small, comparatively robust. Head hypognathous, fastigium verticis roughly conical, apex rounded, with a longitudinal sulcus on dorsal surface. Eyes ovoid, protruding forward. Apical segment of maxillary palpus slightly shorter than subapical one, apical area inflated, apex rounded. Pronotum elongate, anterior margin straight, posterior margin rounded; lateral lobes longer than deep; humerial sinus indistinct. Thoracic auditory spiracle small, exposed, oval. Tegmina broad and short, not reaching or slightly surpassing apices of hind femora, apices rounded; hind wings shorter than tegmina.

All femora without spines on ventral surfaces. Fore coxa with one spine, fore tibia with 4 spines on inner and outer sides of ventral surface separately; tibial tympana open on both sides, long oval. Hind tibia with 28–30 spines on both sides of dorsal surface, one pair of dorsal apical spurs and ventral apical ones respectively.

Tenth abdominal tergite broad, posterior margin concave. Epiproct small, short and broad. Cercus elongate, moderately curved inward and ventrad; base compressed, broad, inner margin with a small conical process; and with a small leaf-shaped process on inner-dorsal margin near the middle; apex of cercus subacute. Genitalia sclerotized, narrow and elongate, lateral margins parallel, depressed, curved afterward and downward, apex rounded. Subgenital plate roughly square, posterior-lateral corners rounded, lightly broadened; styli long on the middle of posterior margin.

Body green. Eyes brown. Genicular lobes of hind femora brown; hind tibiae with spines light brown on dorsal surface.

Female. Unknown.

Specimens examined. Holotype, ♂, Tongbiguan, Yingjiang, Yunnan, 13 August, 2016, coll. Jun Ma. Paratypes: 2♂, Tongbiguan, Yingjiang, Yunnan, 13 August , 2016, coll. Jun Ma ; 2♂, Tongbiguan, Yingjiang, Yunnan, 16 Au- gust, 2018, coll. Yanqing Li and Limin Lu.

Measurements (mm). Body: ♂ 7.1–7.2; pronotum: ♂ 3.7–3.8; tegmina: ♂ 6.7–6.8; hind femora: ♂ 8.4–8.6.

Discussion. The new species differs from other species of the genus in the following: male cercus elongate, inner margin with a small conical process near base, and with a small leaf-shaped process on inner-dorsal margin near the middle; genitalia, narrow and long, lateral margins parallel, depressed, curved afterward and downward, apex rounded.

Etymology. The new species name is derived from male genitalia morphology, Latin gracil- means thin, narrow.
