Diagnosis. This species has the following characters: in the forewing, the three white fasciae are straight and the antemedial fascia does not reach the costal margin; in the male genitalia, the gnathos is a hemicircular band, the costa of the valva is not straight and the juxta is rectangular. These characters are shared with P. kyuparki Kim & Lee, 2016 , but the latter can be distinguished by the right sacculus with a small triangular subapical process instead of a spiniform process.

Redescription. Adult ( Figs 5, 6 , 9a ). Forewing length: males 5.3‒7.2 mm (n = 14) and females 5.4‒6.7 mm (n = 16). Head: vertex dark orange yellow white anteriorly; frons ocherous brown. Antennal scape white except laterally dark brown; flagellomere white basally alternated with dark brown apically. Labial palpus: second palpomere yellowish brown and yellowish white inner surface; third palpomere yellowish brown. Mesonotum and tegula dark orange yellow. Forewing dark orange yellow with three white fasciae edged with black scales; sub-basal fascia not reaching costal margin; antemedial fascia from 1/3 of posterior margin and oblique toward base; medial fascia and costal fascia linear; medial fascia from 1/2 of posterior margin and oblique toward apex; costal fascia from 2/3 of costal margin; fringe cilia orange yellow except grayish orange near tornus. Hindwing and fringe cilia gray. Hind femur and tibia pale gray; tarsus dark brown except white at the apical margin of each tarsomere.

Wing venation ( Fig. 9b ). Forewing wide lanceolate, relatively broad; R 4 and R 5 stalked at 1/2; R 5 to costa; M 1 and M 2 parallel; M 2 approximate toward M 3 from anal angle of cell. Hindwing falcate: M 1 and M 2 slightly parallel; M 3 and CuA 1 stalked from anal angle of cell; 1A + 2A well developed; CuP and 3A weakly developed.

Male genitalia ( Fig. 12 ). Uncus trilobed; middle lobe elongate, widened basally and apex obtuse; flanked by two lateral, small basal lobes. Gnathos belt-like, hemicircular. Valvae asymmetrical. Right valva with costa straight, gradually narrowing to a rounded apex; sacculus strongly incurved from base to subapical part; subapical part with a small, triangular process pointed inwardly; apical process spine-like, acutely upturned. Left valva with costal part narrowed basally, widening apically, extending to acutely-recurved apical process; sacculus strongly incurved, slightly narrowed subapically; apex acutely curved upwardly, larger than right apical process. Juxta rectangular, apex indented medially, about 2x length of uncus. Saccus small, triangular. Phallus broadly curved apically; vesica with single, long spiniform cornutus half length of phallus.

Female genitalia ( Figs 15a, 15b ). Papilla analis narrowly-elongate, obtuse, with setae. Apophysis anterioris 2/5 length of apophysis posterioris. Ostium bursae protruded posteriorly. Lamella antevaginalis triangular, obtuse and overlaying elongated antrum. Antrum elongated, cylindrical, curved toward the right; dilated in anterior half. Ductus seminalis arising from posterior end of ductus bursae. Ductus bursae cylindrical; posterior half straight, dilated, well sclerotized and posterior end spinose; anterior half coiled, one lateral side sclerotized and narrow. Corpus bursae oval, signum absent.

Distribution. Japan (Honshu, Kyushu), China (Fujian, Hunan, Jiangsu, Zhejiang, Shanghai).

Remarks. All individuals examined in the present study were collected in lowlands or pine forests along the coast of Honshu and Kyushu, Japan.
