Diagnosis. The new species is similar to P. zhengi Wang et Li, 2004. It can be distinguished from the latter in the male genitalia by the asymmetrical lateral arms of the juxta, the saccus shorter than the uncus and the cornutus about 1/5 the length of the aedeagus; in P. zhengi, the lateral arms of the juxta are symmetrical, the saccus is longer than the uncus, and the aedeagus is about 2/5 the length of the aedeagus (Wang & Li 2004: 4, fig. 8).
Description. Adult (Fig. 17). Wingspan 6.5–11.0 mm. Head with vertex brown, frons yellowish brown, oc-ciput dark brown with silvery scales. Labial palpus with basal segment pale yellow on inner surface, black on outer surface; second segment black; third segment black except white at base and apex. Scape of antenna brown and with a longitudinal white line on dorsal surface, white on ventral surface; flagellum black alternated with white on dorsal surface, blackish brown on ventral surface. Thorax and tegula black on basal half, ochreous yellow on distal half. Forewing ochreous yellow; costal spot black, sub-quadrate, obliquely crossing anterior margin of cell, edged with a white line on outer margin; distal spot black, sub-triangular; other markings white edged with black scales: cell with a white streak at basal 1/3 and above posterior angle of cell respectively, and a white dot below posterior angle of cell; fold with a short streak at base, above middle and at distal 1/4 respectively; dorsum with three white streaks: one near base, second streak from basal 2/5 reaching middle of fold, third streak from basal 2/3 meeting streak at distal 1/4 of fold, with a diffused blackish brown spot between second and third white streaks; apical spot small; terminal spot between tornus and apex; tornal spot black, diffused to posterior angle of cell; cilia ochreous yellow, black on extension of distal patch. Hindwing and cilia grey. Fore- and midlegs black, except midleg yellow ventrally, tibiae with a white dot at base and middle, with a tuft of white scales at apex, tarsi white at apices of basal two tarsomeres and on entire apical tarsomere of mid tarsus; hindleg yellow ventrally, grey dorsally, tarsus black except white at apices of basal two tarsomeres and on entire apical tarsomere.
Male genitalia (Fig. 34). Uncus campaniform, with sparse setae laterally, wide at base, slightly narrowed to about basal 3/5, distal 2/5 distinctly slender, digitate. Gnathos as long as uncus; mesial plate broadly lingulate, with scale-like protuberances on distal 1/4, obtuse apically, with an ovate, membranous apical process; basal arm short, about 1/3 length of mesial plate. Tegumen broad, divided from posterior 1/2; lateral arm slightly narrowed anteriorly. Valva with basal 3/4 parallel, distal 1/4 slightly narrowed, produced into a thumb-shaped, sparsely setose lobe; costa slightly projected medially, with setae along distal half; sacculus narrow, well-defined to 3/5 length of ventral margin, distal 2/5 densely setose, produced to a free triangular process with an apical spine directed dorsad. Saccus almost parallel to rounded apex, shorter than uncus. Juxta strong and long, slightly asymmetrical: left lateral arm with basal half wide, distal half narrowed to obtuse and curved apex, reaching near posterior margin of tegumen; right lateral arm with basal 2/5 wide, distal 3/5 slightly narrowed to pointed and curved apex, reaching uncus apically; basal lobe clavate, crossing basal 2/3 of saccus.Aedeagus about twice times length of valva, straight; cornutus stout, thorn-like, about 1/5 length of aedeagus.
Female genitalia (Fig. 46). Apophyses anteriores about half length of apophyses posteriores. Eighth sternum sub-rounded, with sparse setae on posterior margin. Antrum very short, sub-trapezoidal, concave on posterior margin, forming two small lateral lobes; narrow band from middle of lateral margin extending to near anterior margin of seventh sternum. Ductus bursae with posterior 2/5 sclerotized, anterior 3/5 membranous, ovoid and with small spines scattered from posterior 2/5 to 2/3, wrinkled anteriorly, curved near corpus bursae. Corpus bursae small, membranous, elliptic; signum absent.
Distribution. China (Chongqing, Guizhou, Hubei, Zhejiang); Japan.
Etymology. The specific epithet of this new species is derived from the Latin medius and macularis, referring to the black sub-quadrate spot in the middle of the costal margin.
