Diagnosis. This species has the following characters: in the forewing, the three white fasciae reach both the costal and posterior margin and a few apical spots are present along termen; in the male genitalia, the valvae are asymmetrical and the apex of the left costa is not concave. This combination of characters is shared with P. dorsoprojecta Du, Zhang & Wang, 2009 , but in this species, the apical patch of the forewing has more than four dots; in the male genitalia, the right lobe of the juxta is elongated and the cornutus is absent in the phallus; in the female genitalia, the lamella postvaginalis is large and semicircular. In P. dorsoprojecta , the apical patch of the forewing has fewer than four dots; in the male genitalia, the right lobe of the juxta is not elongated and a cornutus is present in the phallus; in the female genitalia, the lamella postvaginalis is hat-shaped.

Description. Adult ( Figs 3, 4 View FIGURES 1–6 , 8a View FIGURES 7–9 ). Forewing length 4.7 mm, males 4.5‒5.3 mm (n = 16) and female 5.4 mm in paratype (n = 2). Head: vertex brownish yellow, white anteriorly; frons brownish yellow. Antennal scape white; flagellomere white basally alternated with dark brown apically. Labial palpus with second palpomere brownish yellow and yellowish white inner surface; third palpomere brownish yellow. Mesonotum and tegula brownish yellow. Forewing brownish yellow with four white fasciae edged with dark brown scales; sub-basal fascia not reaching costal margin; antemedial fascia from 1/3 of posterior margin, oblique toward base and reaching costal margin; medial fascia and costal fascia convergent from 1/2 of posterior margin, oblique toward apex and reaching 2/3 of costal margin; five apical spots along termen and apex; fringe cilia pale brownish yellow except blackish brown near costal margin and tornus. Hindwing and fringe cilia gray. Hind femur and tibia ocherous brown; tarsus dark brown except white along apical margins of each tarsomere.

Wing venation ( Fig. 8b View FIGURES 7–9 ). Forewing lanceolate: R 4 and R 5 stalked at 2/3; R 5 to costa; M 1 and M 2 curved, nearly parallel; M 3 approximate toward CuA 1 from base. Hindwing falcate; M 1 and M 2 slightly parallel; M 3 from anal angle of cell; CuP and 1A + 2A weakly developed.

Male genitalia ( Fig. 11 View FIGURES 10–12 ). Uncus lingulate, 1/2 length of gnathos, with setae. Gnathos triangular, narrowed apically with aristate apex longer than uncus. Valvae asymmetrical. Right valva slightly shorter than left, rectangular, costa slightly thickened basally; apex broadly rounded, bearing a dense cluster of spiniform setae; sacculus basally broad, gradually narrowed apically, strongly curved inwardly from base with setae at apical 2/3; apex extending beyond costa, forming a slightly upturned digitate process. Left valva oblong; costa slightly thickened basally; at middle spiniform setae and slightly narrowed apically and broadly-rounded, sparsely setose; sacculus as in right; apex hemicircular with setae. Juxta ensiform and elongate with asymmetrically bifurcate lobes connecting weakly sclerotized plate; base dilated; right lobe straight, thick, ensiform with sub-lobe basally; left lobe more slender and elongated than right lobe, curved at level of right lobe tip, with pointed apex; anterior process clavate, narrowed apically. Saccus triangular, narrowed apically with blunt apex. Phallus straight, narrowed basally and constricted at apical 1/4; vesica tapered medially; cornutus absent; apex with one irregular wrinkled obovate plate and one small process.

Female genitalia ( Figs 14a, 14b View FIGURES 13–15 ). Papilla analis elongate, apically-broadened with setose lobes. Apophysis anterioris 3/5 length of apophysis posterioris. Lamella postvaginalis large, semicircular with setae. Seventh sternum sclerotized around ostium bursae. Lamella antevaginalis hemicircular, protruded apically. Antrum oval, overlaid by lamella antevaginalis and constricted near ductus bursae. Ductus bursae about 5/7 length of antrum, weakly sclerotized at middle, gradually narrowed anteriorly. Ductus seminalis arising from posterior end of ductus bursae. Corpus bursae oval; signum small and ovoid with five small spines anteriorly.

Distribution. Japan (Hokkaido, Honshu).

Etymology. The species is named in honor of the Japanese lepidopterist Hiroyuki Kogi, who collected the holotype and has contributed to the knowledge of the Microlepidoptera fauna in Hokkaido.

Remarks. This species was first recorded in Hokkaido based on one female adult collected by H. Kogi ( Kameda 2010) but was designated only by its Japanese name without description nor scientific name. It was subsequently collected locally at high elevation and in northern areas in Japan, suggesting that the species distribution is driven by mean annual temperature.
