Type material.

Holotype: China • male; Sichuan Province, Mianyang City, Pingwu County, Baima Village ; 4 Aug. 2019; Lu Qiu leg. Paratype: China • 1 female, same collection data as holotype .

Other material examined.

China • 10 oothecae; same collection data as holotype.

Diagnosis.

The male of this species resembles P. latizona sp. nov., but differs in having sparser markings on the tegmina, paler abdominal coloration, and less distinct boundaries of yellow-black abdominal markings. The female of this species has slightly larger ocelli compared to the latter. Additionally, the serrations of the ootheca of this species are slightly stronger than those of P. latizona sp. nov.

Description.

Male holotype. Measurements (mm). Overall length (including tegmen): 35.51; body length: 23.39; body width (tegmina not included): 11.53; tegmen length × width: 30.00 × 9.40; pronotum length × width: 10.28 × 5.91.

Coloration. Pronotum yellowish brown, anterior margin white. Tegmina and hind wings pale yellow, maculae blackish brown (Fig. 12 A, E ). Eyes, vertex, and spaces between ocelli black. Ocelli and ante-clypeus yellowish white. Antennal sockets white. Antennal sockets, post-clypeus, and labrum yellowish brown. Labial palpi and maxillary palpi yellowish brown, distal part and connections white (Fig. 12 G ). Legs yellowish brown, spines and outside of tibia dark yellowish brown to black. Pulvilli and arolia white. Sterna dark yellowish brown, margins and distal part black (Fig. 12 B ).

Body. Head: Sub-rounded, nearly completely hidden under pronotum. Eyes and ocelli developed. Ocelli ridge indistinct, with a row of setae on the upper edge. Interocular space nearly equal to the distance between ocelli, and both narrower than the distance between antennal sockets. Clypeus developed (Fig. 12 G ). Pronotum: Transverse oval, widest near the middle. Densely covered with setae and pubescence, middle part with symmetrical stripe. Anterior whitish margin greatly broad and clearly delineated from yellowish brown areas (Fig. 12 E ). Tegmina and hind wings: Densely covered with small maculae, maculae fused near the base (Fig. 12 A ). Legs: Slender, front femur type C 1. Pulvilli and arolia present (Fig. 12 B ). Abdomen: Supra-anal plate transverse, narrow and pubescent, posterior margin slightly protruded medially. Paraprocts simple. Hind margin of subgenital plate flat, densely covered with setae. Styli columnar (Fig. 12 I, J ). Genitalia: L 1 weakly sclerotized, anterior protrusion round, the left protuberance robust, two posterior lobes curved. L 2 arched, terminal round. Genital hook (L 3) curved in the middle. L 4 M broad lamellate. Pda and paa developed, protrusions long. L 8 long and narrow, flaky. R 1 M widely expanded at terminal part. R 1 L elongate, banded. R 2 divided into two chunks. R 3 broadly concave (Fig. 12 K, L ).

Female paratype. Body length: 25.19 mm; body width: 16.01 mm; pronotum length × width: 9.29 × 5.09 mm.

Coloration. Terga blackish brown. Vertex, eyes, space between ocelli and post-clypeus black. Ocelli and antennae yellowish brown. Ante-clypeus and base of labrum yellowish white. Middle and distal part of labrum yellowish brown. Legs dark yellowish brown to black, spines black. Sterna nearly black, dark yellowish brown in most of central areas (Fig. 12 C, D, H ).

Body. The widest point of pronotum near the hind margin, middle part with symmetrical black stripe. Anterior whitish margin absent (Fig. 12 F ). Ocelli degraded to two spots. Interocular space almost equal to the distance between ocelli, both narrower than the distance between antennal sockets (Fig. 8 H ). Front femur type C 1. Arolia and pulvilli absent. Posterior margin of supra-anal plate protruded, emarginated medially. Cerci short, not exceeding posterior margin of supra-anal plate. Posterior margin of subgenital plate protruded, emarginated medially (Figs 12 C, D , Suppl. material 1: fig. S 1 E).

Nymph. Unknown.

Ootheca. Yellowish brown. Surface with parallel longitudinal lines. Serrations of keel weak, terminal blunt. No respiratory canals (Fig. 15 E, N ).

Etymology.

The species epithet is derived from the type locality, Baima Village, in Pingwu County, Mianyang City, Sichuan Province.

Remark.

The genetic distance between this species and the remaining members of the genus ranges from 12.92 % to 19.70 %, providing support for its classification as a new species.
