Diagnosis.
The salient features of the new species include: gonostyli in ventral view (Fig. 3 G View Figure 3 ) bent into a rectangular shape at apex, inner margins sunken at base forming a small process, middle part protrudes slightly; periandrium (Fig. 3 J – M View Figure 3 ) in ventral margin with a wide lamellar process at apical half, dorsal margin with a long strip-shaped process, tapering to apex, with a long hook-shaped process near the middle.
Type material.
Holotype: China • ♂; Guangxi Province, Huaping National Nature Reserve ; 25°38'N, 109°55'E; sweeping, 9 August 2023; Yong-Jin Sui and Feng-E Li leg.; IEGU GoogleMaps . Paratypes: China • 15 ♂♂, 8 ♀♀; same collection data as for holotype; IEGU GoogleMaps .
Description.
Measurements. Total length: male 6.3–6.6 mm (N = 16), female 7.0– 7.6 mm (N = 8).
Coloration. General color yellowish brown with green (Fig. 3 A, B View Figure 3 ). Vertex foul-brown with green, lateral carinae dark yellow. Eyes gray-brown to brown. Ocelli gray. Frons dark brown at base, rest yellowish brown, lateral carinae yellowish green to dark green, lateral side of head with a triangular turquoise spot anterior to the eyes. Clypeus yellowish brown. Antennae yellowish brown with green at base. Pronotum greyish white with turquoise, brown behind eyes. Mesonotum yellowish brown to brown with green. Tegula yellowish brown. Forewings semi-translucent, grayish white, with many variform yellowish brown to brown and dark brown stripes and markings, stigma yellowish green, veins and tubercles turquoise to green to light yellowish brown, as shown in Fig. 3 E View Figure 3 .
Head and thorax. Vertex (Fig. 3 A, C View Figure 3 ) 1.63 times as long as wide, width at apex narrower than at base (1: 1.73), anterior margin nearly straight, posterior margin U-shaped recessed, lateral carina developed, median carina absent. Frons (Fig. 3 D View Figure 3 ) longer in middle line than wide at widest portion (about 3.65: 1), widest at nearly apex, lateral carina developed, apex of median carina raised. Clypeus (Fig. 3 D View Figure 3 ) with median carina. Pronotum (Fig. 3 A, C View Figure 3 ) shorter than vertex in midline (1: 1.57), posterior margin recessed. Mesonotum (Fig. 3 A, C View Figure 3 ) longer than 2.36 times pronotum and vertex combined. Forewings (Fig. 3 E View Figure 3 ) 2.19 times as long as wide, with twelve apical cells and seven subapical cells, RP 3 branches, MP with 5 terminals: MP 11, MP 12, MP 2, MP 3, and MP 4, fork MP 1 + MP 2 basad of fork MP 3 + MP 4. Hind tibia with six lateral spines.
Male genitalia. Pygofer (Fig. 3 F, G View Figure 3 ) ventral margin distinctly longer than dorsal margin in lateral view, posterior margin convex at middle, lateral lobes arcuate and extended caudally; in ventral view symmetrical, medioventral process short, triangular. Anal segment (Fig. 3 F, H View Figure 3 ) in lateral view flat tubular, dorsal and ventral margins nearly straight; in dorsal view, 2.32 times as long as wide; anal style big, elliptic, not extending beyond anal segment. Gonostyli (Fig. 3 I, G View Figure 3 ) in lateral view L-shaped, curved dorsally near the middle, ventral margin sunken at basal 1 / 3, with a small process; in ventral view lateral margins curved, bent into a rectangular-shape at apex, directed reversely, inner margins sunken at base form a small process, middle part protrudes slightly. Aedeagus (Fig. 3 J – M View Figure 3 ) with a spinose process. Periandrium in ventral margin with a wide lamellar process at apical half, nearly basal part frizzy; dorsal margin with a long strip-shaped process, tapering to apex, with a long hook shaped near the middle, directed ventrocephalad; apical part with a slender spinous process, curved ventrally at base, slowly sloping to straight, then bends almost 90 degrees to the abdomen, directed ventrad. Endosoma slightly sclerotized, without process.
Female genitalia. Tergite IX (Fig. 4 A, D View Figure 4 ) moderately sclerotized, without wax plate. Anal segment (Fig. 4 C View Figure 4 ) rectangular, 1.80 times as long as wide in dorsal view, anal style angular. Gonapophysis VIII (Fig. 4 E View Figure 4 ) elongate, curved upwards. Gonapophysis IX (Fig. 4 F View Figure 4 ) with two middle teeth, denticulation unsharp. Gonoplac (Fig. 4 G View Figure 4 ) rod-like, 6.65 times as long as wide in lateral view. Posterior vagina pattern as shown in Figure 4 B View Figure 4 .
Distribution.
China (Guangxi Zhuang Autonomous Region) (Fig. 1 View Figure 1 ).
Etymology.
The new species is named after its the Guangxi Zhuang Autonomous Region in which it was collected.
Remarks.
This species is similar to P. circinatus Wang & Chen, 2023 , but differs from the latter in: (1) gonostyli in ventral view bent into a rectangular shape at apex (gonostyli in ventral view not bent into a rectangular shape at apex in P. circinatus ); (2) long spinose process of periandrium non-circular at apical part (long spinose process of periandrium circular at apical part in P. circinatus ); and (3) periandrium with a long hook-shaped process near the middle (periandrium without a long hook-shaped process near the middle in P. circinatus ).
