- Phlugiolopsis emarginata Bian, Shi & Chang sp. nov. Figure 4; Map 1 Male. Body small. Fastiguim verticis conical, apex obtusely rounded, furrowed in middle. Eyes kidney-shaped, projecting outwards. Anterior margin of pronotum slightly prominent, posterior margin narrowly rounded; lateral lobes longer than high, humeral sinus absent. All femora unarmed. Procoxae with 1 short spine. Pro- and mesotibiae with 4 internal spines and 5 outernal spines on ventral margin, and a pair of ventral apical spurs; tibial tympana open on internal and external sides, oval. Genicular lobes of postfemora with apices obtuse; posttibiae with 31 pairs of spines on dorsal margin, apex with 1 pair of dorsal spurs and 2 pairs of ventral spurs. Tegmina short, concealed under pronotum, reaching the middle area of second abdominal tergite. Hind wings absent. Posterior margin of tenth abdominal tergite obviously projecting backwards, centre with deeper notch. Epiproct tongue-shaped, furrowed in middle. Basal margin of male cerci stout, expanded on internal margin, the interno-dorsal lobe arch-shaped, the interno-ventral lobe rectangular, its antero-lateral corner curved dorsad; apical half compressed, slightly curved upwards, apex subacute. Subgenital plate with broad base, narrowing, basal margin arched excavate; lateral margins bent dorsad; apical area broadly trapezoidal projecting, centre of posterior margin with U-shaped concavity, the lateral lobe obtusely rounded. Subapex of subgenital plate with thin, long and conical styli on ventral margin, the apices obtuse. Female. Appearance is similar to male. Cerci conical, apices acute. Ovipositor short, gently curved upwards, base stout, narrowing, dorsal and ventral margins smooth; dorsal valvulae slightly longer than or as long as ventral ones; dorsal valvulae sharply pointed and ventral ones with 1 small terminal hook. Basal half of subgenital plate nearly rectangular, basal margin slightly straight; apical half narrowly triangular, apex projecting backwards, centre with shallowly concavity. Coloration. Body yellowish brown. Eyes brown. Internal margin of antennal socket, scape and pedicel light black. Dorsum of male head with 4 black brown stripes; disc of pronotum brown, outer area with 1 pairs of black brown stripes, the subapical area indistinct. Apices of postfemora black; ventral spines of tibiae and whole tarsi light brown. Dorsum of abdominal tergites light brown, lateral margins black brown; sterna light black. Basal half of male subgenital plate light brown. Typical material. Holotype, ♂, Ma ′andi, Jinpin, Yunnan, 8 September, 2012, coll. Xun Bian and Guanglin Xie. Paratypes, 1 ♂ 3 ♀, other information as the holotype. Measurements (mm). Body: ♂ 8.1–8.4, ♀ 9.3–9.7; pronotum: ♂ 3.6–3.7, ♀ 4.3–4.6; tegmen: ♂ 1.7–1.9, ♀ 1.3– 1.4; postfemur: ♂ 7.8–7.9, ♀ 8.6–8.9; ovipositor: 6.0– 6.1. Distribution. China (Yunnan). Discussion. The new species resembles P. brevis Xia & Liu, 1993 and P. tuberculata Xia & Li, 1993, but differs from them in: (1) basal half of male cerci with 1 arch-shaped interno-dorsal lobe and 1 rectangular internoventral lobe; apical half compressed, slightly curved upwards, apex subacute; (2) male subgenital plate with broad base, narrowing to apex, basal margin arched excavate; lateral margins bent dorsad; apical area prominent, centre of posterior margin with U-shaped concavity, the lateral lobe obtusely rounded; (3) basal half of female subgenital plate nearly rectangular, basal margin slightly straight; apical half narrowly triangular, apex projecting backwards, centre with shallowly concavity. Etymology. The name of the new species is derived from the central concavity of posterior margin in male tenth abdominal tergite.
