Diagnosis.
This species is similar to
P. longivalvaris
Wang,
2016
in both the forewing pattern and the male genitalia. It can be distinguished by the valva gradually narrowed to about distal 1/4 and thereafter slightly narrowed to apex, the broad sub-triangular saccus less than 1/4 the length of the valva, and the curved cornutus in the male genitalia; in
P. longivalvaris
, the valva is widened to about distal 1/3 and then distinctly narrowed to apex, the elongate clubbed saccus is more than half the length of the valva, and the cornutus is straight.
Description.
Adult (
Fig. 2
) wingspan
7.5 mm
. Head with vertex cream white, frons grayish yellow, occiput brownish yellow. Labial palpus with first and second segments blackish brown on dorsal surface except second segment white before apex and black at apex, yellow on ventral surface; third segment black except white on dorsal 1/3 and at apex. Antenna with scape white; flagellum blackish brown, alternated with cream white dorsally. Thorax and tegula reddish brown. Forewing yellow, mixed with yellowish brown scales; markings white edged with black scales: both basal and antemedian fasciae reaching costal margin; antemedian fascia wider, from beyond basal 1/4 of costal margin straightly oblique outward to middle of dorsum; costal spot at distal 1/3, sub-rounded, reaching lower corner of cell; pre-tornal stripe slender, as long as costal spot; apical spot irregular in shape; cilia gray except white on extension of white apical spot. Hindwing and cilia light grayish brown. Fore- and midlegs black, with a white tuft of long scales at apex of mid tibia, white at apex of each tarsomere; hindleg with femur and tibia yellow tinged with brown, tarsus brown except white at apex of each tarsomere.

Male genitalia (
Fig. 10
). Uncus with basal half uniformly broad, distal half narrowed to pointed apex. Gnathos elongate, rounded apically; lateral arms wide at base, narrowed to middle. Tegumen widened medially, divided and narrowed from about middle. Valva narrowed at base, widened to about basal 2/3, then narrowed to apex, apex with a short spine directing dorsad; costa convex medially, with sparse setae; distal 2/5 of ventral margin with sparse setae. Sacculus wide at base, narrowed to end, reaching basal 3/5 of ventral margin. Saccus elongate, clubbed, more than half length of valva, thickened distally, narrowly rounded at apex. Juxta small, ovate, both lateral and basal lobes indistinct. Aedeagus approximately 1.5 times length of valva, almost uniform, with dense denticles in basal half except smooth at base; cornutus slender, very long, extending from near base to about distal 1/4 of aedeagus, curved in S shape, bifurcate distally and forming two apical spines.
Female unknown.

Etymology.
The specific epithet is derived from the Latin
curv
- (curved) and the Latin term
cornutus
, referring to the curved cornutus.
