Diagnosis.
The salient features of the new species include: gonostyli in ventral view (Fig. 5 G View Figure 5 ) bent into a rectangular shape at apex, with an angular process near the middle; dorsal margin of periandrium (Fig. 5 J – M View Figure 5 ) with a hook-like process near the middle, ventral margin with a wide subquadrilateral process nearly basal to the middle part; slender spinose process of periandrium circular at apical part.
Description.
Measurements. Total length: male 6.4–6.7 mm (N = 4), female 7.5 mm (N = 1).
Coloration. General color brown (Fig. 5 A, B View Figure 5 ). Vertex dark brown, lateral carinae yellowish brown. Eyes red-black. Ocelli faint red. Frons yellowish brown to dark brown, lateral carinae light yellowish brown at basal half, rest brown, lateral side of head with a grey-brown spot anterior to the eyes. Clypeus yellowish brown. Antennae gray-brown. Pronotum greyish white, yellowish brown behind eyes. Mesonotum brown at middle part, yellowish to yellowish brown at lateral sides. Tegula yellowish brown. Forewings semi-translucent, grayish white, with many variform yellowish brown to brown and dark brown stripes and markings, stigma yellowish brown, veins and tubercles greyish white to yellowish brown, as shown in Figure 5 E View Figure 5 .
Head and thorax. Vertex (Fig. 5 A, C View Figure 5 ) 1.51 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. 5 D View Figure 5 ) 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. 5 D View Figure 5 ) with distinct median carina. Pronotum (Fig. 5 A, C View Figure 5 ) shorter than vertex in midline (1: 1.57), posterior margin recessed. Mesonotum (Fig. 5 A, C View Figure 5 ) longer than 1.76 times pronotum and vertex combined. Forewings (Fig. 5 E View Figure 5 ) 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. 5 F, G View Figure 5 ) ventral margin distinctly longer than dorsal margin in lateral view, posterior margin with middle part distinctly convex, lateral lobes arcuate and extended caudally; in ventral view symmetrical, medioventral process short, angular. Anal segment (Fig. 5 F, H View Figure 5 ) in lateral view flat tubular, dorsal margin almost straight, ventral margin curved slightly; in dorsal view apical part angular, 2.42 times as long as wide; anal style tonguelike, big, not extending beyond anal segment. Gonostyli (Fig. 5 I, G View Figure 5 ) in lateral view curved dorsally, L-shaped, ventral margin with a dentoid process, directed cephalad; in ventral view bent into a rectangular shape at apex, directed reversely, middle part of inner margins broad suddenly, with an angular process. Aedeagus (Fig. 5 J – M View Figure 5 ) with a spinose process. Periandrium in ventral margin with a suboblong lamellar process at apical part, nearly basal to the middle part with a wide subquadrilateral process; dorsal margin with a hook-like process near the middle, tapering to apex, directed ventrocephalad; apical part with a slender process, curved ventrally at base, slowly sloping, then curved in a circle from middle part to proximal apex, directed cephalad. Endosoma slightly sclerotized, without process.
Female genitalia. Tergite IX (Fig. 6 A, D View Figure 6 ) moderately sclerotized, without wax plate. Anal segment (Fig. 6 C View Figure 6 ) rectangular, 1.82 times as long as wide in dorsal view, anal style egg-shaped. Gonapophysis VIII (Fig. 6 E View Figure 6 ) elongate, curved upwards. Gonapophysis IX (Fig. 6 F View Figure 6 ) with two middle teeth, denticulation unsharp. Gonoplac (Fig. 6 G View Figure 6 ) rod-like, 6.32 times as long as wide in lateral view. Posterior vagina pattern as shown in Figure 6 B View Figure 6 .
Distribution.
China (Yunnan Province) (Fig. 1 View Figure 1 ).
Etymology.
The species name is derived from the Latin word “ hamatus ”, referring to the dorsal margin of the periandrium with a hook-like process near the middle.
Remarks.
This species is similar to P. fuscus Wang & Chen, 2023 , but differs from the latter in: (1) forewing with several large variform markings at basal 2 / 3, apex light brown, with a few pale spots and small dark brown markings (forewing with a few small stripes at basal 2 / 3, apex dark brown, with a few pale spots in P. fuscus ); (2) gonostyli bent into a rectangular shape at apex (gonostyli not bent into rectangular shape at apex in P. fuscus ); and (3) dorsal margin of periandrium with a hook-like process near the middle (dorsal margin of periandrium without a hook-like process near the middle in P. fuscus ).
