Redescription. Adult ( Fig. 11 ). Wingspan 9.0–10.0 mm. Head white, mixed with yellow or yellowish brown scales. Labial palpus white; second segment blackish brown in basal half; third segment longer than second, black near apex. Antenna with scape yellow, mixed with brown; flagellum alternately yellowish white and blackish brown. Thorax and tegula white. Forewing ground color white, with black markings: sub-basal patch slightly narrowed from costa to dorsum; costa with a relatively small spot at basal 1/3, with a large subrectangular spot at basal 2/3 reaching upper margin of cell; several tiny dots placed distally along costa; discocellular spot small, almost connected with tornal spot; tornal spot small, reaching below discocellular spot; cilia grayish white to grayish brown. Hindwing and cilia grayish brown. Legs yellowish white, mixed with blackish brown scales; tarsi black, each tarsomere white apically.

Male genitalia ( Fig. 22 ). Eighth sternum with posterior margin produced trapezoidally, anterior margin almost straight. Uncus quadrate, slightly narrow basally, posterior margin almost straight, setose, posterolateral corner rounded. Gnathos subovate horizontally, anteromedian process narrow triangular. Tegumen furcate from posterior 2/5, triangularly projected posteriorly; lateral branch banded, narrowed anteriorly. Glandiductor symmetrical, extremely slender, dilated basally, strongly curved at basal 1/6, exceeding top of uncus. Valva subrectangular; outer lobe straight, clubbed, distally dilated, setose; inner lobe short, approximately 1/4 length of outer lobe. Juxta with basal 3/7 rectrangular, bearing a sparsely setose papillary lobe at 3/7; distal 4/7 slender, clavate, slightly narrowed and hooked from before apex, longer than outer lobe of valva. Vinculum inverted triangular; saccus narrow, rectangular, shorter than vinculum. Aedeagus slightly shorter than tegumen, slender, dilated basally, distal 1/3 truncate.

Female genitalia ( Figs. 31 , 38 ). Eighth sternum subtrapeziform, posterior margin straight, sparely setose. Apophyses anteriores slightly shorter than half length of apophyses posteriores. Ostium bursae with lateral lobes heavily sclerotized, elongate triangular, narrowed to acute apex. Antrum short and narrow, shorter than lateral lobes of ostium bursae, narrower than ductus bursae. Ductus bursae longer than two times length of corpus bursae. Corpus bursae round; signum scaphoid, posterior margin straight, anterior margin concave, spines anterolateral.

Diagnosis. This species is similar to P. albicapitella in wing color and pattern, and the differences between them are stated under the latter species.

Distribution. China (Henan, Zhejiang, Taiwan).
