1 Euxiphidiopsis erromena Shi & Mao sp. nov.

Male Body slightly larger. Fastigium verticis conical, apex obtusely rounded, with a longitudinal sulcus. Eyes globular, prominent forwards. Apical segment of maxillary palpus almost as long as subapical one, apex enlarged. Pronotum comparatively long, anterior margin straight, posterior margin rounded; posterior transverse sulcus distinct; lateral lobes of pronotum longer than deep, humeral sinus indistinct. Thoracic auditory spiracle oval. Tegmina long, surpassing apices of postfemora; hind wings a little longer than tegmina. Femora of all legs without spines on ventral surface; procoxae with a spine, protibiae with 6 spines on inner side and 7 spines on outer side of ventral surface separately, the spines near base of protibiae longer, apical spines short; tibial tympana open on internal and external sides. Posttibiae with 30–32 spines on inner and outer sides of dorsal surface separately, and a pair of dorsal apical spurs and two pairs of ventral apical spurs. Tenth abdominal tergite with a conical posterior process, membranous area slightly broad. Epiproct small, semi-membranous. Cerci stout in base 2/3 part, inner surface concave, 1/3 apices thiner, incurved, separated into short dosal and ventral lobes. Subgenital plate with base slightly broad, narrowing, posterior margin truncate; styli long on apices of lateral margins of subgenital plate.

Coloration. Body green. Fastium verticis brown, apex light brown. Disc of head with 4 stripes, two stripes on inner area usually indistinct, the two outer stripes distinct. Pronotum with a pair of longitudinal brown stripes, the area between stripes light brown, the outer margins with a pair of yellow stripes. Stridulatory area light brown.

Type material. Holotype: male, Guangxi: Rongshui, Jiuwandashan, August 6, 2006, collected by Fu-Ming Shi and Shao-Li Mao.

Measurements (mm). Male: body: 12.0; pronotum: 5.0; tegmina: 21.0; postfemora: 13.0.

Discussion. The new species differs from known species of the genus in: 2/3 base of male cerci stout, inner surface concave, 1/3 apices thin, incurved, separated into dorsal and ventral short lobes.

Etymology. The name of the new species is derived from male’s cercus morphology.

Distribution. China (Guangxi).
