DIAGNOSIS. This species is similar to Odites notocapna Meyrick, 1925 in the external appearance and body size but differs from the latter in the presence of the white forewings (pale yellow in O. notocapna ) and the lack of marginal dots on the forewings.

DESCRIPTION. HABITUS ( Figs 1, 2 ). Head: Vertex and frons lustrous, white. Labial palpus upcurved, acuminate apically; 1st segment 1/7 as long as 2nd, brownish gray; 2nd segment white, tinged with brownish gray on basal 6/7 of lateral surface; 3rd segment 4/5 as long as 2nd, white, tinged with dark brown on apical area. Antenna 2/3 as long as forewing, ciliate in males, filiform in females; scape white dorsally, pale-brownish gray ventrally; flagellum pale-brownish gray, tinged with white on basal 1/5.

Thorax: Patagium white; tegula and mesonotum pale-brownish gray. Forewing length 5.3–6.2 mm, lustrous, white, tinged with pale-brownish gray along dorsum; discal cell with black spot at middle and distal end; tornus with a black spot; cilia white. Hindwing and cilia pale gray. Foreleg grayish brown, intermixed with white scales on ventral surface of coxa and femur. Midleg with coxa and femur whiten, intermixed with grayish brown scales on dorsal surface; tibia and tarsomeres grayish brown dorsally, white ventrally. Hindleg with coxa pale orange; femur, tibia and tarsomeres pale gray.

Abdomen pale-brownish gray, intermixed with pale-yellowish gray laterally.

MALE GENITALIA ( Figs 3–6 ). Tegumen oblique laterally; gnathos bifid, as long as transtilla; transtilla inverted-subtriangular. Valva ear-shaped, densely-hairy, with bulge at subbasal area of subcostal and elliptical cavity at saccular base; costal process arising near base, strongly-curved, expanded subtriangularly in terminal 2/3. Vinculum subtriangular; juxta elliptical. Aedeagus stout, narrowed distad, with three spiniform cornuti.

FEMALE GENITALIA ( Fig. 7 ). Ovipositor telescopic. Sternite VIII sclerotized. Papillae anales narrow, setose. Apophyses posteriores 2.5x longer than apophyses anteriores. Ostium bursae moderate. Antrum columnar. Ductus bursae short, expanded near corpus bursae, spinulated and wrinkled on anterior 1/2. Corpus bursae elliptical, with two spinose, elliptical signa at middle.

REMARKS. Miyano (2022) reported three undescribed species of Scythropiodes .

Of them, the new species described here is possibly conspecific with Scythropiodes sp. C .

DISTRIBUTION. Korea, Taiwan.

ETYMOLOGY. This species is named after Dr. Sung-Soo Kim, a famous lepidopterologist in Korea, in honor of his contributions to the knowledge of the Korean lepidopteran fauna.
