Figures 1–2
Description. Male. Body small. Fastigium verticis conical, apex obtusely rounded, dorsal surface with 1 thin furrow (Fig. 1A). Eyes nearly semiglobular, projecting outwards. Apical segments of maxillary palpi longer than subapical ones, apices faintly inflated (Fig. 1B).
Pronotum short, anterior margin of pronotum straight, posterior margin narrowly rounded, protruding backward; lateral lobes longer than deep, narrowing to backward, humeral sinus absent (Fig. 1B). Tegmina overlapped and concealed beneath pronotum, or slightly surpassing the apex of pronotum, reaching the posterior margin of second abdominal tergite, apices rounded; hind wings absent (Fig. 1B).
Procoxae with 1 spine. All femora unarmed; apices of genicular lobes of postfemora obtusely rounded. Ventral surface of protibiae with 4 pairs of spines, apices with 1 pair of spurs; protibial tympana oval, opened on both sides. Mesotibiae with 2 internal spines, 4 external spines and 1 pair of apical spurs on ventral surface. Posttibiae with 27–29 internal spines and 25–30 external spines on dorsal surface, ventral surface with 1–3 internal spines and 3–5 external spines, apices with 1 pair of dorsal spurs and 2 pairs of ventral spurs.
Posterior margin of tenth abdominal tergite faintly concave in middle (Fig. 1C). Cerci short, interno-dorsal margin of basal half widely lobate expansion, which extends to the middle area of ventral margin; apical half slender and spine-shaped, its apex directing interno-dorsad, apices acute (Fig. 1C). Subgenital plate with basal area transverse, narrowing to backward, basal margin rounded concave, lateral margins curved dorsally, posterior margin narrowly rounded (Fig. 1F). Styli conical, apices obtuse, inserted at the subapical area of subgenital plate on ventral surface (Fig. 1F).
Female. Appearance similar to male. Eighth abdominal tergite with 1 small conical process on each side (Fig. 2C); posterior margin of ninth abdominal tergite arched; tenth abdominal tergite short, the middle of posterior margin slightly concave (Fig. 2C). Styli short and stout, conical (Fig. 2D). Ovipositor short, gradually upcurved behind basal third area, base stout, narrowing from basal to apical area, dorsal and ventral margins smooth, apices of dorsal valvulae acute, apices of ventral ones hook-shaped (Fig. 2E). Subgenital plate pentagonal, basal margin arched concave, lateral margins subparallel, apical half subtriangular, apex acute (Fig. 2F).
Coloration. Body yellowish brown. Eyes brown. Internal margins of antennal sockets dark brown; scape, internal margins of pedicel and the base of the first segments of flagellum dark brown, the other flagellar segments with brownish rings. Dorsal surface of head with 4 longitudinal stripes. Pronotal disc with 1 longitudinal brownish stripe in the center, lateral margins with 1 dark brown stripe on each side (Fig. 1A). Apices of mesofemora blackish, apices of genicular lobes of dark. The basal and apical areas of all tibiae pale brown. Abdominal tergites blackish brown on dorsal surfaces, lateral margins dark brown, and abdominal sternites pale brown.
Material examined. Holotype: male, Yangmeiao, Huanjiang, Guangxi, September 3, 2021, coll. by Jing Liu. Paratypes: 7 males and 6 females, the other information as holotype; 1 female, Rongshui, Guangxi, August 8, 2021, coll. by Jing Liu; 1 male and 1 female, Yangmeiao, Rongshui, Guangxi, September 4, 2021, coll. by Jing Liu and Xiangyi Lu. Other specimens: 1 female, August 17, 2021, the other information as holotype; 2 males and 1 female, Yangmeiao, Huanjiang, Guangxi, September 3, 2021, coll. by Jing Liu; 1 male and 1 female, September 3–4, 2021, coll. by Jing Liu and Xiangyi Lu, the other information as holotype.
Measurements (mm). Body: ♂ 6.5–7.6, ♀ 7.3–7.9; pronotum: ♂ 3.6–3.7, ♀ 3.6–3.7; tegmen: ♂ 1.8–2.1, ♀ 1.7–2.0; postfemur: ♂ 7.8–8.0, ♀ 8.2–8.4, ovipositor: 5.4–5.5.
Distribution. Guangxi (Huanjiang, Rongshui).
Discussion. The new species is similar to Phlugiolopsis brevis Xia & Liu, 1993 (Chinese name: üḡ吟ª), but differs from the latter by posterior margin of male subgenital plate rounded projecting without a concavity in middle; female subgenital plate pentagonal with ventral surface not concave and middle area of apex not raised. The species differs from Phlugiolopsis pentagonis Bian, Shi & Chang, 2013 (Chinese name: 五ø吟ª) as follows: apical half of female subgenital plate triangular, apex acute; while female subgenital plate of Phlugiolopsis pentagonis Bian, Shi & Chang, 2013 with round posterior margin.
Etymology. The name of the new species is derived from apex of female subgenital plate acute.
