Xizicus (Zangxizicus) quadrifascipes Wang, Jing, Liu, Li sp. nov.

( Figs. 15–22 )

Materials. Holotype ♂, Motuo , Xizang, China, alt. 1060m, 2011.VIII.6–8, leg. BI Wen-Xuan.

Description. Male. Fastigium of vertex conical, apex blunt, disc with a longitudinal sulcus ( Fig. 17 ). Subapical segment of maxillary palpi approximately equal to apical one. Metazona of pronotum longer than prozona, hind margin of lateral lobe oblique, humeral sinus inconspicuous. Tegminal tip far exceeding apex of hind femora, and shorter than wings by 1.0 mm ( Fig. 15 ). All femora unarmed, fore coxa bears a spine, fore tibia with spines armed ventrally of type 4,5 (1,1), tibial tympana oval, each dorsal margin of hind femora with 26–30 teeth, 3 pairs of apical spurs armed on terminal. Middle of 10 th abdominal tergite slightly protruded, without processes ( Figs. 18, 20 ). Cerci tapering caudally, inner surface of base with a wider dorsal lobe and a sharper ventral lobe ( Figs. 18, 20 ). Subgenital plate long and narrow, apex rounded, subapex with a pair of small tubercle which may be the vestiges of styli ( Figs. 19, 22 ).

Female unknown.

Coloration. Body yellowish brown and darkish brown. Disc of vertex compact 4 dark longitudinal lines, converge at fastigium; middle of face, inner margin of scrobe and three basal segments of antenna darkish brown, antenna darkish annulated. Dorsum of pronotum brownish, pair of dark discontinuous stripes laterally. Tegmina darkish brown, vein pale yellow. Fore and mid leg with darkish rings, hind femora with 4 darkish latitudinal bands on outer surface, tibial spines and dorsal abdomen darkish brown. Cerci light yellow, apical half dark.

Etymology. The specific epithet from Latin ‘quadri’ + ‘fascipes’, stands for stripes of hind femora.

Distribution. China (Xizang).
