Phlugiolopsis longiangulis Bian, Shi & Chang sp. nov.

Figure 5 ; Map 1

Male. Body small. Fastiguim verticis conical, apex obtusely rounded, furrowed in middle. Eyes subglobular, projecting outwards.

Anterior margin of pronotum slightly prominent, posterior margin narrowly rounded; medial carina indistinct; lateral lobes longer than high, humeral sinus absent.

All femora unarmed. Procoxae with 1 small spine; protibiae with 4 inner spines and 5 outer spines on ventral margins; tibial tympana open on both sides, ovoid. Mesotibiae with 4 pairs of ventral spines and a pair of of ventral apical spurs. Apices of postfemora obtuse; posttibiae with 31 pairs of dorsal spines, 1 pairs of dorsal apical spurs and 2 pairs of ventral apical spurs.

Tegmina short, posterior margin without suppressing the posterior margin of pronotum, only reaching the middle area of second abdominal tergite. Hind wings absent.

Posterior margin of tenth abdominal tergite with arch-shaped middle concavity. Basal half of cerci stout, interno-dorsal margin lobate expansion; middle area with 1 semicircular dorsal lobe and 1 triangular ventral lobe; apical half spine-shaped, strongly incurved, apex acute. Basal margin of subgenital plate arched excavate, lateral margins bent dorsad, gradually narrowing to apex, apical half siliquiform projecting, apex obtusely rounded. Styli slender, conical, apex obtuse, positioned on ventral margin of subapex of subgenital plate.

Female. Body slightly larger, tegmina surpassing the posterior margin of pronotum, extending the middle area of third abdominal tergite. Cerci conical, apex acute. Ovipositor short, gently curved upwards, dorsal and ventral margins smooth, base stout, narrowing, apices of dorsal valvulae pointed, ventral ones with a small terminal hook. Four-fifths of basal area of subgenital plate broadly rectangular, basal margin almost straight, apical area obtuseangular, apex obtuse, slightly concave in middle.

Coloration. Male body yellowish-brown, female light 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; lateral lobes light brown. 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.

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: ♂ 7.9–8.4, ♀ 8.0–8.2; pronotum: ♂ 3.1–3.5, ♀ 3.1–3.3; tegmen: ♂ 1.6–1.8, ♀ 1.2– 1.3; postfemur: ♂ 7.3–7.9, ♀ 8.5–8.7; ovipositor: 6.0–6.1.

Distribution. China (Yunnan)

Discussion. The new species resembles P. brevis Xia & Liu, 1993 and P. emarginata Bian, Shi & Chang sp. nov., but differs from them in: (1) Basal half of male cerci stout, interno-dorsal margin lobate expansion; middle area with 1 semicircular dorsal lobe and 1 triangular ventral lobe, the apex obtuse; apical half spine-shaped, strongly incurved, apex acute. (2) Basal margin of male subgenital plate arched excavate, lateral margins bent dorsad, gradually narrowing to apex, apical half siliquiform projecting, apex obtusely rounded. (3) Four fifths basal area of female subgenital plate broadly rectangular, basal margin almost straight, apical area obtuse-angular, apex obtuse, slightly concave in middle.

Etymology. Named in reference to the shape of apical half in the male subgenital plate of this species.
