Fig. 6

Description. Male Body small. Head short, fastigium verticis conical, apex rounded, furrowed dorsally. Eyes oval, protruding forward and outward. Apical segment of maxillary palpus lightly shorter than subapical one, apical area inflated, apex rounded.

Pronotum relatively longer, anterior margin roughly straight, posterior margin rounded; lateral lobe longer than high; humeral sinus indistinct. Thoracic auditory spiracle comparatively large, exposed, peanut-shaped.

All femora without spines on ventral surfaces. Fore tibia with 4 spines on both sides of ventral surface; tibial tympana open on both sides, long oval. Hind tibia with 28–31 spines on both sides of dorsal surface, one pair of dorsal apical spurs and ventral apical spurs respectively.

Tegmen longer, surpassing apex of abdomen, but not reaching apex of hind femur, base broad, tapering, apex rounded. Hind wing shorter than tegmen.

Tenth abdominal tergite short, posterior margin concave. Cercus divided into two branches; dorsal one short directed upwards and backwards, apex rounded; ventral one longer, directed ventrad, apex subacute. Genitalia with base broad, apex rounded, dorsal surface of subapex with a thin process, apex arrow-shaped. Subgenital plate with base broad, apex narrow; styli obviously long on lateral margins of subapex of subgenital plate.

Coloration. Body green. Eyes brown. Hind tibia with spines black.

Female. Body thin. Ovipositor narrow, moderately upcurved, apex acute. Subgenital plate broad, posterior margin lightly concave.

Specimens examined. Holotype: ♂, Neibang, Yingjiang, Yunnan, 17 August, coll. Jun Ma. Paratype: 1♀, Neibang, Yingjiang, Yunnan, 17 August, coll. Jun Ma.

Measurements (mm). Body: ♂ 8.8, ♀ 8.3; pronotum: ♂ 4.7, ♀ 3.8; tegmina: ♂ 10.0, ♀ 9.8; hind femora: ♂ 9.8, ♀ 10.5; ovipositor: 6.0.

Discussion. The new species differs from the congeners in: male cercus divided into two branches, dorsal branch short directed upwards, apex rounded; ventral one longer, directed ventrad, apex subacute; genitalia with base broad, apex rounded, dorsal surface of subapex with a thin process, apex arrow-shaped.

Etymology. The name of the new species is named after male genitalia morphology, the word arrow comes from English.
