Diagnosis.
The salient features of the new species include: anal style (Fig. 2 H View Figure 2 ) extending beyond anal segment; gonostyli in ventral view (Fig. 2 G View Figure 2 ) fist-shaped at apex, basal 1 / 3 and 2 / 3 with emarginations; periandrium (Fig. 2 J – M View Figure 2 ) 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 View Figure 2 ). 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 View Figure 2 .
Head and thorax. Vertex (Fig. 2 A, C View Figure 2 ) 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 View Figure 2 ) 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 View Figure 2 ) with distinct median carina. Pronotum (Fig. 2 A, C View Figure 2 ) shorter than vertex in midline (1: 1.57), posterior margin recessed. Mesonotum (Fig. 2 A, C View Figure 2 ) longer than 2.31 times pronotum and vertex combined. Forewings (Fig. 2 E View Figure 2 ) 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 View Figure 2 ) 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 View Figure 2 ) 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 View Figure 2 ) 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 View Figure 2 ) 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 View Figure 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 ).
