Diagnosis. The color and pattern of wings are similar to those of P. ignigera Meyrick , comb. nov. ( Fig. 6 View FIGURES 1 – 14 ), which was described from Papua, Indonesia, but it can be distinguished by following characters: the antenna dark brown in the basal 2/5, then shiny, orange white, whereas blackish throughout in P. ignigera ; the costal dark brown streak beyond median fascia narrower, nearly straight; the outer margin of the orange median zone on the forewing slightly angled at middle, whereas strongly angled between M1 and M 2 in P. ignigera Meyrick ; the hindleg almost entirely pale yellow, whereas that of P. i g n i g e r a with distinct black markings.

Description. Adult ( Figs. 5, 13 View FIGURES 1 – 14 , 16, 20−22, 26 View FIGURES 15 − 30 , 32 View FIGURES 31 − 33 c). Wingspan, 18−20 mm. Head: Dark brown dorsally; face orange white. Antenna about 1.3 times longer than length of forewing, with dark brown basal joint; flagellum dark brown in basal 2/5, then shiny, orange white, fascicularly ciliated with short hair-like cilia. Labial palpus in male with second segment stout, long, strongly recurved, thicker before middle, pale orange in basal 3/5, then dark brown beyond, acute apically; third segment absent. In female, second segment normally thickened, gently curved, light to pale orange on lateral surface, dark brown dorsally and ventrally; third segment very slender, slightly shorter than second, dark brown dorsally. Thorax: Collar dark brown. Tegula and thorax dark brown. Fore tibia pale orange latero-dorsally, dark brown ventrally; mid tibia pale orange with dark brown scales at base of ventral side; hind tibia with dark orange appressed scales dorsally, pale orange ventrally. Forewing elongate; brownish basal fascia developed in 2/5 length of wing; large, trapezoidal, dark orange patch well-developed, with straight upper margin and convex outer margin, in which a large, dark brown quadrate spot connected to upper dark brown costal streak medially; costa nearly straight in median part, then arched beyond 3/4, with dark orange streak along margin anteriorly; apex obtuse; termen oblique, slightly sinuate; fringe paler than ground color of wing, with narrow darker band medially; venation with R1 arising from middle of cell; R2 and R3+4 short-stalked, about at basal 1/10 length; R3 and R4 stalked at basal 2/5 length; R4 reach before apex; R5 absent; M1 remote; M2 absent; M3 approximate to CuA1+2; CuA1 and CuA2 stalked at basal 1/6 length. Hindwing broader than forewing; costa nearly straight; ground color dark orange, with short, dark brown basal fascia and apical dark brown fascia arising from 2/ 3 length of costa, attenuated to basal 1/3 length of inner margin, with a large dark brown, trapezoidal spot medially; apex sharply produced; termen strongly oblique; fringe paler than ground color of wing, with paler narrow basal line, followed by darker subbasal line; venation with Rs and M1 short-stalked; M2 absent; M3 and CuA1 connate; CuA2 arising from middle of cell. Hind tibia clothed with pale orange scales dorsally, orange white apically. Abdomen: Deep orange dorsally, with dark brown first segment and few terminal segments; dark-brown spots along lateral sides; tergites II −VII with spinous zones.

Male genitalia ( Figs. 32, 32 View FIGURES 31 − 33 a −b) with uncus elongate, dilated distally, bent downward, dense setose on dorsal surface, with round apex. Gnathos absent. Tegumen weakly sclerotized, more or less triangularly terminated distally. Valva elongate, as long as tegumen+vinculum; costa sclerotized band in basal half, with large triangular concavity basally; ventral margin concave at basal 2/5 length; cucullus elongate, occupied about distal 3/5, with strong bristles on surface; sacculus broadly developed, extended to 2/5 length on ventral margin. Juxta sclerotized, broadly concave on caudal margin. Aedeagus broad at base, narrower towards apex, bifurcate apically; cornuti with a sheaf of bristles, occupying 1/3 length of aedeagus.

Female genitalia ( Figs. 37, 37 View FIGURES 34 − 40 a −b) with abdominal sternite VIII weakly sclerotized, gently concaved on caudal margin. Apophyses anteriores about 1/2 length of apophyses posteriores. Antrum bowl-shaped, weakly sclerotized, less than 1/2 of width. Ductus bursae about 1/4 length of corpus bursae; ductus seminalis arising from posterior part. Corpus bursae elongate; posterior 1/3 narrow, membranous; middle part weakly sclerotized, broader towards apex, about 2/3 length; anterior 1/3 rounded, densely wrinkled; signum plate rounded, scobinate, about 1/4 width of corpus bursae.

Distribution. Papua New Guinea.

Etymology. The species is named in honor of Prof. Sang-Dae Park, in recognition of his contributions to the development of the biology in Korea.
