Figure 2 ; Map 2

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

Anterior margin of pronotum slightly prominent, posterior margin obtusely rounded; lateral lobes longer than high, humeral sinus absent.

All femora without spines on ventral margins. Procoxae with a small spine; protibiae with 4 pairs of spines and a pair of apical spurs on ventral surface; tibial tympana open on both sides, ovoid. Mesotibiae with 3 spines on anterior margin and 4 spines on posterior margin of ventral surface, and a pair of ventral apical spurs. Genicular lobes of postfemora with apices obtuse; posttibiae with 24–26 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 under pronotum, posterior margin reaching the middle area of third abdominal tergite. Hind wings absent.

Posterior margin of tenth abdominal tergite slightly projecting backwards, centre of which slightly concave. Epiproct tongue-shaped, furrowed in middle. Basal half of cerci lobate expansion on internal margin, internodorsal lobe comparatively wider, semicircular, interno-ventral feebly narrow, subtriangular, the apical half pointed interno-dorsad, apex obtuse; apical half of cerci compressed, curved inwards and slightly upwards, apex subacute. Subgenital plate with broad base, gradually narrowing, basal margin arched concavity, lateral margins bent dorsad, apex projecting, trapezoid, posterior margin almost truncate. Styli slender, conical, apex obtusely rounded, inserted on ventral margin of subapical area of subgenital plate.

Female. Similar to male appearance, slightly larger. 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. Subgenital plate nearly semicircular, basal margin comparatively straight, posterior margin arch-shaped.

Coloration. Male body black brown, female yellowish brown. Eyes light brown. Internal margin of antennal socket, scape and pedicel black brown. Dorsum of male head black brown, with 4 indistinct light brown stripes; disc of pronotum black brown, outer area with black stripes, which extending the middle area of metazona, disc and outer area brown in some specimens; lateral lobes light brown. Dorsum of female head with 4 black stripes; pronotum with a pair of black brown stripes on lateral margins of disc, between area darker. Apices of postfemora, ventral spines of tibiae and whole tarsi light brown; dorsal spines of posttibiae black. Male cerci yellowish brown.

Type material. Holotype, ♂, Xisha, Yongshan, Yunnan, 28 August, 2012, coll. Xun Bian and Guanglin Xie. Paratypes: 15 ♂ 8 ♀, other data as the holotype.

Measurement (mm). Body: ♂ 7.3–7.6, ♀ 7.4–8.1; pronotum: ♂ 4.1–4.3, ♀ 4.2–4.3; tegmen: ♂ 2.0–2.1, ♀ 2.0– 2.5; postfemur: ♂ 7.3–7.6, ♀ 8.7–8.9; ovipositor: 5.4–5.9.

Distribution. China (Yunnan)

Discussion. The new species is similar to P. trullis Bian, Shi & Chang, 2012 , but it differs from the latter: male cerci expanded on internal margin, interno-dorsal lobe semicircular, interno-ventral lobe subtriangular, posterior margin of subgenital plate truncate; female subgenital plate semicircular, posterior margin arch-shaped.

Etymology. Named in reference to the characteristically compressed apical half of the male cerci.
