description: Naryciodes koreana n. sp.
Naryciodes posticalis (nec Matsumura, 1931); Heo, 2016: 195 (misidentification).
Diagnosis. This species is closely related to Naryciodes posticalis Matsumura (Fig. 3), but can be distinguished from the latter in having the narrower, dark brown suffusion on the forewing, and the narrower apex of the valva in the male genitalia (Figs. 5 a & 6a). Differences between N. posticalis and N. koreana are most obvious in their larvae. Differing from those of N. koreana, the larvae of N. posticalis possess tubercles on anterior angles and at the center of the body (Kuroko 1983; Nakamura 1987; Murase 2011).
Adults (Fig. 1). Head—Vertex pale brownish gray; scales of frons pale yellowish gray, darkened distally. Antenna 3/ 7 as long as forewing; scape pale yellowish gray, intermixed with fuscous scales; flagellomere pale yellowish gray, intermixed with dark brown scales. Labial palpus oblique, acuminate apically; 1st segment 1/4 as long as 2nd, dark brown, with pale yellowish gray band distally on inner surface; 2nd segment 2× length of 3rd, pale brownish gray, intermixed with fuscous scales on outer surface, pale yellowish gray on inner surface; 3rd segment pale yellowish gray, paler on inner surface.
Thorax—Patagium grayish brown; tegula pale brownish gray, intermixed with brownish gray scales, tinged with dark brown apically and basally; mesonotum pale yellowish gray, intermixed with dark or pale brownish gray scales, tinged with dark brown on posterior 1/7. Foreleg with coxa dark brown, sparsely irrorated with pale brownish gray distally; femur pale yellowish gray, tinged with dark brown on ventrobasal half of inner surface; tibia and tarsomeres dark brown, with pale yellowish gray ring distally. Midleg with coxa pale yellowish gray, tinged with brownish gray distally; femur pale brownish gray, intermixed with fuscous scales basally; tibia and tarsomeres dark brown dorsally, pale grayish orange ventrally, with pale yellowish gray ring distally. Hindleg with coxa pale yellowish gray, tinged with brownish gray distally; femur pale yellowish gray, intermixed with pale grayish brown scale on outer surface; tibia pale grayish orange, intermixed with fuscous scales ventrally; tarsomeres brownish gray, dorsally, pale grayish orange ventrally, with pale yellowish gray ring distally. Forewing length 8.8–11.7mm (n=4), subrectangular, gradually broadened to termen, pale yellowish gray, suffused with dark brown on costal and basal areas; discal spot elliptical, broadly dark brown, with pale brown bar medially; subterminal line as dark grayish brown shade, with zigzagged outer margin along veins; adterminal line comprising black dashes; fringe brownish gray. Hindwing dark yellowish gray, paler basoanteriorly; fringe brownish gray.
Abdomen—Dorsal area pale yellowish brown, suffused with fuscous scales; ventral area pale yellowish brown, sparsely intermixed with dark brown scales. Male genitalia (Fig. 5): Uncus elongate, pointed apically, with small, triangular basal plate; tegumen trapezoidal, bulged lateroposteriorly, as long as uncus; valva elongate, obovate, narrowly round apically, slightly convex at basal 2/5 of costa; sacculus narrow, slightly broadened, setose on basal 1/3; vinculum subquadrate; juxta V-shaped, medially-emarginated along anterior margin; anellus spinulate; phallus (Fig. 5 a) as long as uncus, with triangular carina posteriorly; cornutal zone spinulate, 2/3 as long as carina. Female genitalia (Fig. 7): Papilla analis subtriangular, setose; apophysis posterioris as long as antrum; apophysis anterioris absent; antrum bowl-shaped; ductus bursae 1.5× longer than corpus bursae, moderately broad, of even width; corpus bursae obovate; signum pairedcrescentiform, juxtaposed with denticulate area.
Larvae (Fig. 2). Body length 9–12mm, elliptical, dome-shaped, pale yellow, tinged with pink anteriorly; medial groove intermittent; lateral groove wrinkled.
