(Figs 57–64)
Holotype ♂, Paratype 2♀, Maoer Mountain, Xing’an County, Guangxi province, alt. 1100–1700m, 2013. VII.30–VIII.6, leg. LIU Xian-Wei et al.; 1♀, Maoer Mountain, Xing’an County, Guangxi province, alt. 900–1500m, 1992. VIII.22–23, leg. LIU Xian-Wei & YIN Hai-Sheng.
Description. Male. Body medium-sized. Fastigium of vertex conical, shallowly furrowed, apex obtuse. Last two segments of maxillary palp about of equal lengths. Pronotum narrow and elongate, anterior edge faintly truncate and posterior edge pointedly rounded of disc, paranota much higher, lateral angle rounded, and humeral sinus inconspicuous. Wings well developed, far exceeding abdominal terminal, hind wings longer than tegmina by 1.0mm. Each femur unarmed. Fore tibiae bearing ventral spines on internal and external edge of type 4, 5 (1, 1); 6 outer and 5 inner ventral spines on mid tibia; hind tibia with 31–34 dorsal teeth on each margin above, and 3 pairs of apical spurs. 10th abdominal tergite concave distad of middle, with a vertically downward middle process which divide into two apically (Fig. 60). Cerci moderately incurved, apex cornuted, dorsal margin sinuated also expanded as a dorsal lobe of which angular at terminal, ventral margin straight and forming a lobe (Figs 60–62). Subgenital plate elongate, base wide tapering towards terminal, apically branched, styli absent (Figs 60, 61). Genitalia entirely membranous.
Female. Appearance roughly similar to that of male. Cerci slender, conical. Ventral edge of 8th abdominal tergite inflated, lateral corner of 9th abdominal tergite backwards extended. Apex wider than base of subgenital plate, posterior edge bearing one middle and two lateral small notches (Fig. 63). Ovipositor shorter than hind femur, straight but upcurved in terminal third, ventral valve bearing an apical hook (Fig. 64).
Coloration. Generally greenish while alive. Disc of pronotum brown and pale fringed. Some cell of tegmina darkish as dark spots. Each genicular lobe with dark apex, each hind tibial spine and tarsus darkish.
Diagnosis. This new species similar to Xiphidiopsis (Dinoxiphidiopsis) jacobsoni Gorochov, 1993, and very close to Xiphidiopsis fanjingshanensis Shi & Du, 2006 which should be also included in Xiphidiopsis (Dinoxiphidiopsis) (deal with it below), but different from latter by weaker dorsal lobe of male cerci, collapsed and wider hind processes of male 10th abdominal tergite (Fig. 43), longer and narrower subgenital plate of male without specialized apical ventral lobe (Fig. 45).
Measurements. Lengths in millimeter: body ♂10.0, ♀10.5; pronotum ♂4.0, ♀4.0; tegmina ♂18.0, ♀19.0; hind femora ♂11.0, ♀12.0; ovipositor ♀9.0.
Etymology. The specific epithet from Latin ‘expressus’, corresponding the feature of male 10th abdomen tergite. The gender of the epithet is masculine.
Distribution. Guangxi (Maoer Mountain).
