Description. Imago ( Fig. 25 View FIGURES 25–34 ) with wingspan 9.0−10.0 mm. Head with vertex shining white, frons brown, occiput ochreous brown. Labial palpus with basal and second segments ochreous yellow on outer surface, basal segment pale yellow on inner surface, second segment yellow on inner surface; third segment dark ochreous brown, slightly shorter than second. Antenna with scape white; flagellum white and black on dorsal surface, dark brown on ventral surface. Thorax, tegula and forewing ochreous brown. Forewing with basal white fascia from base of costal margin to basal 1/5 of dorsal margin, second white fascia parallel to first one, extending obliquely from about costal 1/3 to middle of dorsum, above two white fasciae edged with black scales; costal margin with a somewhat oval white spot at about 3/4, extending down across midwing, margined with black scales except on anterior margin; dorsal margin with a dark-gray streak from distal 1/5 extending upward to lower angle of cell, then curved down to beyond tornus, edged with black scales; apex dark gray, termen scattered with black scales; cilia yellow, dark gray along distal part of costal and dorsal margins. Hindwing and cilia dark gray. Foreleg black, tibia with white spot at base and middle, with a tuft of short white scales at apex on dorsal surface, tarsus with white spots on dorsal surface; midleg with tibia and tarsus pale gray on ventral surface, dark ochreous brown on dorsal surface, tibia with white spot at base, with a tuft of long white scales at apex, tarsus with white spots on dorsal surface; hindleg yellow on ventral surface, dark gray on dorsal surface, tarsus white in distal half on dorsal surface.

Male genitalia ( Fig. 56 View FIGURES 53–58 ). Uncus broad at base, gradually narrowed to 1/2, distal 1/2 slender, digitate, hooked apically, basal 1/2 narrowly folded inward and setose laterally. Gnathos about 2/3 length of uncus, nearly triangular, distal 1/3 scobinate, with a small papillary process at apex; lateral arms band shaped, slightly shorter than gnathos. Tegumen elongate, concave at anterior 1/4 laterally, branched from posterior 1/3, blunt anteriorly. Valva narrow, almost parallel dorso-ventrally; costa projected at middle, concave near apex; apex rounded, deeply concave in an U shape before apex ventrally, forming a digitate ventro-subapical process, which is overlapped with sacculus and reaches ventral margin of sacculus apically. Sacculus with basal 2/3 narrow, broadened before apex, distally produced to a narrow triangular free process, which is serrate on ventral margin and has a small apical spine; with a small notch at dorsal 2/5, distal half with dense setae. Saccus slender, rod-like, about 1.3 x length of uncus, rounded at apex. Juxta small, nearly Y shaped, acute anteriorly. Aedeagus with basal half straight, distal half sinuate, about 1.4 x length of valva, slightly expanded apically; one spine-like cornutus distally, about 1/3 length of aedeagus.

Female genitalia ( Fig. 71 View FIGURES 70–73 ). Apophysis anterioris stronger than and about 4/5 length of apophysis posterioris. 7th sternum large, specialized and forming large, sclerotized rectangular plate laterally, membranous medially. 8th sternum short, sclerotized, hill-like, with dense spinules and sparse setae. Lamella antevaginalis sclerotized, irregularly rounded, slightly narrow posteriorly, serrate marginally except on posterior margin. Antrum large, nearly racket shaped. Ductus bursae with posterior half thin and sclerotized, anterior half expanded and membranous, with an ovate weakly sclerotized plate at anterior 1/4, with a small spine on its surface; ductus seminalis arising from middle of ductus bursae. Corpus bursae nearly rounded, with dense granules; one irregularly plate-shaped signum present, densely toothed superficially and marginally, with a large tooth at each end.

Diagnosis. This new species is similar to P. parasuzukiella Wang, 2006 . It can be separated by the valva having a digitate ventro-subapical process, the sacculus produced to a narrow triangular free process, the aedeagus having one spine-like cornutus in the male genitalia; the antrum racket shaped, and the ductus bursae with basal half sclerotized in the female genitalia. In P. parasuzukiella , the valva has no ventro-apical process, the sacculus is not separated distinctly from valva and the aedeagus has no cornutus in the male genitalia; the antrum is bowl shaped and the ductus bursae is membranous in the female genitalia.

Distribution. Philippines (Palawan, Tawi Tawi).

Etymology. The specific name is derived from the Latin superimpositus (= overlapped), referring to the ventro-apical process of the valva overlapping with sacculus apically in the male genitalia.
