Allicyrtaspis globosis Shi, Bian & Chang sp. nov.

(Map. 1, Fig. 1 )

Male. Body small. Head stout and short. Fastigium frontis faintly inclined, fastigium verticis conical with apex obtusely rounded, furrowed on dorsum. Eyes subglobular, protruding laterally. Apical segment of maxillary palpi slightly longer than subapical one, apex slightly swollen.

Pronotum protruding backwards, surpassing posterior margin of second abdominal tergite, anterior margin straight, indistinctly concave, posterior margin obtusely rounded; anterior and median transverse sulci indistinct, posterior transverse sulcus distinct; posterior margin of paranota slightly broadened, without humeral sinus. Thoracic auditory spiracle comparatively large, oval.

All femora not bearing spines on ventral margin. Procoxa with a spine, inner and outer sides of ventral margin of protibiae with 5 spines respectively (including a pair of ventral apical spines); tibial tympana open on both sides, Elongate-oval. Mesotibiae with 3–4 spines on inner side and 4–5 spines on outer side of ventral margin. Genicular lobes of postfemora with apices obtuse, posttibiae with 22–25 spines on inner and outer sides of dorsal margin separately, and a pair of dorsal apical spurs and two pairs of ventral apical spurs.

Tegmina short, not reaching posterior margin of pronotum, or slightly surpassing posterior margin of pronotum, apices faintly truncate; hind wings absent.

Ninth abdominal tergite with central area short lateral margins moderately extended. Tenth abdominal tergite ( Fig. 1 C) obviously protruding backwards, basal area slightly broad, apical half narrow, the lateral margins slightly broadened, ventral margin of the central area prominently undulate; posterior margin with a broad V-shaped notch. Cercus ( Fig. 1 D) short, basal area globular, apical half thin, apex obtusely rounded, not surpassing posterior margin of tenth abdominal tergite, partially hidden under tenth abdominal tergite. Genitalia long, surpassing posterior margin of tenth abdominal tergite, sclerotized, apical half area curved upwards, apex widened, rectangle-shaped, concave, centre of posterior margin with a notch. Subgenital plate ( Fig. 1 E) elongate, basal area concave, posterior area with an obtuse angular notch, the middle area convex; styli stout and short, conical, located on apices of lateral margins of subgenital plate, directed inwards.

Coloration. Body light yellowish green (probably green when alive), some area yellowish brown. Fastigium verticis with a longitudinal brown stripe. Eyes light brown. Disc of pronotum with a pair of longitudinal brown stripes, slightly diverging afterwards, which disappear near posterior area of pronotum. Apical area of posttibia spines, spurs and claws brown. Dorsal margin of abdomen with a longitudinal light brown stripe. Female. Unknown.

Type material. Holotype: 3, Yunshan, Wugang, Hunan, China, collected by Jian-Hua Huang. Measurements (mm). Body: 314.0; pronotum: 36.1; tegmen: 3 2.0; postfemur: 310.8. Distribution. China (Hunan).

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