Type material. CHINA: Holotype ♂, Guangxi Zhuang Autonomous Region: Mt. Daming , 1250 m, 21.V.2011, coll. Linlin Yang and Yinghui Mou, genitalia slide No . CPX15160. Paratypes: 5 ♂, 4 ♀, 22–27.V.2011, other same data as holotype, genitalia slide Nos . CPX15144♂, CPX15163♀, CPX15205♂, CPX15218♀.
Diagnosis. This species is close to P. tauricornis sp. nov. in both appearance and genitalia, and the differences between them are stated under the latter species.
Description. Adult ( Fig. 13 View FIGURES 11 – 16 ): Wingspan 8.0–10.0 mm. Head yellowish brown, mixed with dark brown. Labial palpus yellowish brown on dorsal surface, dark brown on ventral surface, each segment yellowish brown apically. Antenna with scape white on ventral surface, yellowish brown mixed with dark brown on dorsal surface; flagellum blackish brown. Thorax yellowish brown mixed with dark brown, blackish brown along apical margin; tegula yellowish brown mixed with dark brown. Forewing with ground color lutescent, covered with dense blackish brown scales that form numerous irregular blackish brown reticular markings and stripes of unequal size; costal margin with dense transverse blackish brown strigulae interrupted by lutescent scales, extending to or beyond upper margin of cell, with a small lutescent spot at distal 1/5; cell with a sub-rectangular blackish brown spot at distal 1/3, extending to fold posteriorly and to before upper angle of cell anteriorly, joined with about four transverse strigulae between middle and distal 1/4 of costal margin; black spot below middle of fold connected with blackish brown strigulae from dorsum; dorsum with several blackish brown strigulae alternated with lutescent, somewhat extending to fold, with a blackish brown spot at tornus; cilia lutescent, mixed with dark brown. Hindwing and cilia pale brown. Foreleg with coxa blackish brown, femur white on dorsal surface, blackish brown on ventral surface, tibia blackish brown, with white streak at base and at middle on outer surface respectively, tarsus blackish brown, first and second tarsomeres white apically on outer surface; midleg with coxa white, femur white on dorsal surface, brown mixed with white on ventral surface, tibia blackish brown except apical spur white, with white streak on outer surface at base and middle respectively, tarsus blackish brown, first and second tarsomeres white apically on outer surface; hindleg with coxa and femur white, tibia pale greyish brown on outer surface, remaining part white, tarsus dark brown, each tarsomere with a white streak apically. Abdomen greyish brown on dorsal surface, white on ventral surface.
Male genitalia ( Fig. 29 View FIGURES 29 – 34 ): Socius oblique outwards, basal 2/3 uniformly wide, subparallel laterally, covered with sparse long setae; distal 1/3 gradually narrowed to pointed apex, curved inwards, smooth. Tegumen medially extended beyond half length of lateral band, anterior margin concave semicircularly at middle, forming rounded process laterally; lateral band slightly oblique outwards anteriorly. Gnathos widely banded, concave at middle anteriorly. Valva broad, bearing long setae, distal half separated from sacculus, bluntly rounded apically, dorsal margin protruded semicircularly at middle, covered with dense strong setae; transtilla narrowly banded; sacculus slender, longer than valva, basal 1/4 protruded triangularly on ventral margin, bearing dense setae, concave almost by a right angle at basal 1/3, distal 2/3 uniformly narrow, extending obliquely ventrad, apex rounded; elliptical membranous area between basal 2/5 of sacculus and valva, covered with dense spinules. Vinculum broad V-shaped; saccus about half length of socius, expanded distally, rounded apically. Juxta semicircular; anellus lobe sub-quadrate except narrowed at proximal base, arising from inner margin of juxta anteriorly, extending obliquely inwards, thorn-shaped apically. Aedeagus slender, approximately 2.3 times length of valva, somewhat thick in basal 1/3, thinner and uniform in distal 2/3, slightly curved at basal 1/3; cornuti being a cluster of spines, placed from distal 2/5 to 3/5 of aedeagus.
Female genitalia ( Fig. 41 View FIGURES 39 – 43 ): Apophyses posteriores about 1.3 times length of apophyses anteriores. Lamella postvaginalis being a pair of narrowly banded processes, oblique outwards, with sparse long setae. Antrum cup-like, widened posteriorly; ductus bursae about half length of corpus bursae, sclerotized except a small membranous area posteriorly; ductus seminalis arising from posterior margin of corpus bursae. Corpus bursae pear-like; signum triangular, heavily sclerotized posteriorly, dentate laterally, placed near middle.
Distribution. China (Guangxi).
Etymology. The specific name is derived from the Latin longi- and sacculus, referring to the sacculus longer than the valva in the male genitalia.
