Allicyrtaspis conicicersus Shi, Bian & Chang sp. nov.

(Map.1, Fig. 2 )

Male. Body stout. Fastigium frontis slightly inclined; fastigium verticis conical, apex obtusely rounded, with median sulcus. Eyes oval, prominently protruding forwards. Apical segment of maxillary palpus slightly longer than subapical one, apex slightly swollen.

Pronotum ( Fig. 2 A) produced posteriorly, surpassing posterior margin of second abdominal tergite; anterior transverse sulcus indistinct, median and posterior transverse sulci distinct; anterior margin straight, posterior margin obtusely rounded; paranota ( Fig. 2 B) with posterior margin slightly broadened; humeral sinus absent. Thoracic auditory spiracle comparatively large, oval.

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

Procoxa with 1 long spine, protibia with 5 spines on inner and outer sides of ventral margin separately; tibial tympana opened on both sides, long oval. Mesotibiae with 5 spines on inner side and 6 spines on outer side of ventral margin. Genicular lobes of postfemur with apices obtuse, posttibiae with 18–20 spines on inner and outer sides of dorsal margin respectively, having a pair of dorsal apical spurs and two pairs of ventral apical spurs.

The central area of ninth abdominal tergite ( Fig. 2 C) narrower, lateral margins protruding backwards. Tenth abdominal tergite obviously projecting posteriorly ( Figs. 2 C, E–F), basal area broader, middle area constricted, apical area broadened, anchor-shaped ( Figs. 2 C, E) in lateral view, posterior margin split, the ventral margin with a pair of cylindrical projections, apices rounded ( Figs. 2 D, F). Cercus ( Figs. 2 E–F) feebly elongate, basal portion stout, apical portion narrow, curved upwards, apices rounded. Genitalia sclerotized, longer than subgenital plate, cylindrical, apical half curved upwards, apex widened, rectangular. Subgenital plate ( Figs. 2 F–G) elongate, basal area concave, lateral margins parallel, posterior margin with a shallow notch; styli cylindrical ( Fig. 2 G), apices obtusely rounded, located on the lateral apices of subgenital plate.

Coloration. Body light yellowish brown (probably yellowish green when alive). Disc of pronotum with a pair of longitudinal brown stripes, which disappear near posterior area of pronotum. Apices of posttibia spines and claws brown.

Female. Unknown.

Type material. Holotype: 3, Huangsha, Lingui, Guangxi, 17 August, 2006, coll. Shao-Li Mao and Li-Juan Wang. Paratype: 13, the other data as holotype.

Measurement (mm). Body: 312.0–13.0; pronotum: 35.7–6.0; tegmen: 31.1–1.3; postfemur: 39.6–9.8.

Discussion. The new species differs from Allicyrtaspis globosis sp. nov. in male tenth abdominal tergite, cerci, subgenital plate and genitalia.

Distribution. China (Guangxi).

Etymology. The name of the new species is derived from male cercus morphology, Greek conic+cersus.
