Figure 7 ; Map 2

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

Anterior margin of pronotum faintly prominent, posterior margin obtusely rounded, median carina indistinct; lateral lobes longer than high, humeral sinus absent.

All femora unarmed. Procoxae armed with 1 spine; protibiae with 4 spines on anterior margin and 5 spines on posterior margin of ventral surface, and a pair of ventral apical spines; tibial tympana open on both sides, ovoid. Mesotibiae with 4 pairs of ventral spines and a pair of ventral apical spines. Genicular lobes of postfemora with apices obtuse; posttibiae with 28–30 spines on anterior and posterior margin of dorsal surface separately, and a pair of dorsal apical spurs and 2 pairs of ventral apical spurs.

Tegmina short, concealed by pronotum, only reaching the middle area of second abdominal tergite. Hind wings absent.

Posterior margin of tenth abdominal tergite slightly projecting with shallow concavity in middle. Basal area of cerci with 1 digitiform ventral process, the apical half pointed dorsad; middle area depressed, dorsal margin with 1 small tooth, the apex acute; apical half spine-shaped, right-angularly incurved, apex obtuse. Basal area of subgenital plate comparatively broad, basal margin arch-shaped excavate, lateral margins bent dorsad, apical area projecting backwards, linguiform, posterior margin almost straight. Subapex of subgenital plate with 1 pairs of conical styli on ventral margin, apex obtuse.

Female. Appearance similar to male, slightly larger. Posterior margin of eighth abdominal tergite obviously concave, lateral margins with 1 long digitate process, pointed backwards; ninth abdominal tergite faintly broad, lateral areas slightly expanded; tenth abdominal tergite short and small. Cerci conical, apex acute. Ovipositor gently curved upwards, base stout, narrowing, dorsal and ventral margins smooth, apices of dorsal valvulae acute, ventral ones with a small terminal hook. Subgenital plate wider than long, medial carina distinct, basal margin with 1 V-shaped concavity, the lateral lobe obtuse; lateral margin bent ventrad; posterior margin angularly projecting, shallowly 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, reaching the middle area of metazona. Apices of postfemora black; ventral spines of tibiae and whole tarsi light brown. Abdominal tergites and sterna black brown.

Typical material. Holotype, ♂, Ma ′andi, Jinpin, Yunnan, 4 September, 2012, coll. Xun Bian and Guanglin Xie. Paratypes, 2 ♂ 4 ♀, the other information as the holotype.

Measurements (mm). Body: ♂ 7.5–7.8, ♀ 8.5–8.9; pronotum: ♂ 3.8–4.0, ♀ 4.1–4.6; tegmen: ♂ 1.7–1.9, ♀ 1.4– 1.6; postfemur: ♂ 7.8–8.1, ♀ 8.4–8.6; ovipositor: 5.3–5.5.

Distribution. China (Yunnan).

Discussion. The new species resembles P. montana Wang, Liu & Li, 2012, but differs from it in: basal area of cerci with 1 digitiform ventral process, middle area depressed, dorsal margin with 1 small tooth, apical half spineshaped, right-angularly incurved, apex obtuse; apical area of male subgenital plate projecting backwards, linguiform, posterior margin almost straight; lateral margins of female eighth abdominal tergite with 1 long digitate process, directed posteriorly, subgenital plate with distinct medial carina, basal margin with V-shaped concavity, lateral margin bent ventrad; posterior margin angularly projecting, shallowly concave in middle.

Etymology. The name is derived from the shape of male cerci in ventral view.
