Paratypes: China • 1 &male;; Yunnan Province, Mengla County, Mohan Town; 21°11'N, 101°41'E; sweeping, 11 August 2023; Yong-Jin Sui leg.; IEGU. • 1 &male;; Yunnan Province, Mengla County, Menglun Town, Bakaxiaozhai Village; 21°58'N, 101°13'E; sweeping, 8 August 2023; Sha-Sha Lv leg.; IEGU. • 1 &male;; Yunnan Province, Jinghong City, Menglong Town, Guohe Village; 21°45'N, 100°51'E; sweeping, 13 August 2023; Feng-E Li leg.; IEGU.Diagnosis.The salient features of the new species include: anal style (Fig. 2 H) extending beyond anal segment; gonostyli in ventral view (Fig. 2 G) fist-shaped at apex, basal 1 / 3 and 2 / 3 with emarginations; periandrium (Fig. 2 J – M) in dorsal margin with a lamellar process, extending to apex to form a thin process, directed ventrad, base to 2 / 3 with a long stripy process.Description.Measurements. Total length: male 6.1–6.4 mm (N = 4).Coloration. General color greyish white (Fig. 2 A, B). Vertex yellowish with green. Eyes brown. Ocelli faint red. Frons yellowish brown, median carina dark yellow, lateral carinae pale yellowish green, lateral side of head with a triangular yellowish-green spot anterior to the eyes. Clypeus yellowish brown with green, carinae brown. Antennae grayish green. Pronotum with median part dark grayish green, lateral sides white with a little green. Mesonotum yellowish to brown. Tegula yellowish brown. Forewings semi-translucent, grayish white, with many variform pale yellowish green and dark brown stripes and markings, stigma light yellowish brown, veins and tubercles green to yellowish brown, as shown in Fig. 2 E.Head and thorax. Vertex (Fig. 2 A, C) 1.38 times as long as wide, width at apex narrower than at base (1: 2.22), anterior margin nearly straight, posterior margin U-shaped recessed, lateral carina developed, median carina absent. Frons (Fig. 2 D) 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. 2 D) with distinct median carina. Pronotum (Fig. 2 A, C) shorter than vertex in midline (1: 1.57), posterior margin recessed. Mesonotum (Fig. 2 A, C) longer than 2.31 times pronotum and vertex combined. Forewings (Fig. 2 E) 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 five lateral spines.Male genitalia. Pygofer (Fig. 2 F, G) 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 long, equilateral triangular. Anal segment (Fig. 2 F, H) in lateral view flat tubular, dorsal margin straight, ventral margin curved slightly; in dorsal view, 1.48 times as long as wide; anal style big, triangular, extending beyond anal segment. Gonostyli (Fig. 2 G, I) in lateral view L-shaped, curved dorsally near the middle, ventral margin with a notch at basal 1 / 3; in ventral view lateral margins curved, widens towards the end, fist-shaped at apex, basal 1 / 3 and 2 / 3 with emarginations. Aedeagus (Fig. 2 J – M) with a spinose process. Periandrium in dorsal margin with a lamellar process, extending to apex, forming a thin process, directed ventrad; apical part with a slender spinous process, curved ventrally at base, then strong bending, directed caudad; base to 2 / 3 with a long stripy process. Endosoma slightly sclerotized, without process.Distribution.China (Yunnan Province) (Fig. 1).Etymology.The species name is derived from the Latin word “ elongatus ”, referring to periandrium with a long stripy process at base to 2 / 3.Remarks.This species is similar to P. circinatus Wang & Chen, 2023, but differs from the latter in: (1) anal style extending beyond anal segment (anal style not extending beyond anal segment in P. circinatus); (2) gonostyli in ventral view fist-shaped at apex (gonostyli in ventral view not fist-shaped at apex in P. circinatus); and (3) periandrium with a long stripy process at base to 2 / 3 (periandrium without a long stripy process at base to 2 / 3 in P. circinatus).
