LIU Xian-Wei, ZHU Wei-Bin, WANG Han-Qiang, ZHANG Hai-Guang . Description. Male. Fastigium of vertex conical, apex blunt, furrowed on middle of disc. Subapical segment of maxillary palpi about equal to apical segment. Metazona of pronotum no longer than prozona ( Fig. 7 ), hind margin of lateral lobe oblique, humeral sinus inconspicuous. Tegmental end far exceeded apex of hind femora, and shorter than wings by 2.0 mm. All femora armless, fore coxa bear a spine, fore tibia with ventral spines armed of type 4,5 (1,1), tibial tympana ovoid, hind tibiae with 29 – 31 dorsal teeth each margin above and 3 pairs of apical spurs. Hind margin of 10 th abdominal tergite with a small process which branches at base, and concave on area where this process attaches ( Figs. 8, 11–12 ). Cerci moderately incurved, apex branched, base with a quadrate ventral lobe ( Figs. 11–12 ). Subgenital plate extremely upcurved, apex sulcus into two spines, and middle of lateral margin where near the base with a small finger-shaped process, which may be the vestiges of styli ( Figs. 12–13 ). Female. Body form similar to that of male. Fastigium of vertex little shorter and base wider than that of male, a shallow furrow on the dorsum, last segment of maxillary palpi equal to preceding. Hind margin of lateral lobe oblique, humeral sinus absent, metazona shorter. Cerci short, apex thin and acute; subgenital plate nearly triangular, hind margin sunk at midst ( Fig. 14 ). Ovipositor long and straight, upcurved and gently raised in height apically, ventral valve with an apical hook ( Fig. 6 ). FIGURES 4–14 . Xizicus ( Paraxizicus ) fallax sp. nov. 4, 5.

Tip of male abdomen, lateral view. Coloration. Body yellowish brown. Disc of vertex compact 4 dark longitudinal lines, converge at fastigium, upper edge of scrobe and three basal segments of antenna darkish brown, antenna darkish annulated. Disc of pronotum brownish, fringed with dark discontinuous purfles either margin aside. Tegmina with conspicuous dark spots, female wings dark. 3 rd thoracic segment of female dark laterally, dorsum of female abdomen tergite blackish. Tibial spines of ambulatorial leg darkish, geniculation of hind femora darkish. Ovipositor with a dark transverse band in basal one-third. Measurement. (in mm) Body ♂ 10.0–10.5, ♀ 11.2; pronotum ♂ 4.1–4.5, ♀ 4.1; tegmina ♂ 19.1–19.5, ♀ 17.5; hind femora ♂ 12.0–12.1, ♀ 12.0; ovipositor ♀ 11.2. Etymology. The specific epithet from Latin ‘fallō’, means very similar to Xizicus ( Paraxizicus ) biprocerus . Diagnosis. The general appearance of this species very similar to Xizicus ( Paraxizicus ) biprocerus , the differences are the small and, short process at hind margin of male 10 th abdominal tergite, ventral lobe of cerci and absence of lateral spines at subgenital plate. Distribution. China ( Guangxi , Jiangxi ).
