Diagnosis. Superficially, the new species is very similar to O. captiosana (Falkovitsh, 1960) and O. subtilana (Falkovitsh, 1959). It can be distinguished from the latters by the curved angle of the preterminal fascia in the forewing that is situated near the tornus, whereas in the other two related species the preterminal fascia in forewing is situated near the termen. If compare the male genitalia of the new species with O. captiosana, the uncus of the new species is setose, bifurcated, and narrower. The new species possess a small spinous patch present at the middle of the sacculus. Also, the phallus of the new species is longer, than that of O. captiosana; cornutus is absent in the new species.
Description. Male (Figs 1a, 1b). Head: Frons ivory; vertex ivory mixed with dark gray scales. Antenna filiform, covered with dark brown scales. Ocellus present. Labial palpus slightly upcurved and covered by ivory scales with a dark brown line on the outer surface, segment 2 with a dark brown mark, segment 3 exposed at the tip, erect, mixed with dark gray scales.
Thorax: Patagium and tegula with yellowish-orange scales. Forewing length 15–18 mm, forewing elongatesubtriangular, broad; costa slightly curved outwards; apex pointed; termen convexly rounded; ground color orangeyellow, costal strigulae weak; basal area with three metallic silver, longitudinal streaks, second streak joined at a nearly right angle from the costal streak, costal streak oblique, extending slightly inward; subbasal fascia with a slightly curved metallic silver cross line, nearer to the median fascia, reticulated; median reticulated fascia with four metallic silver markings in the center of dark ovoid patch consisting of irregular dots and lines; preterminal fascia curved inward, near tornus; terminal fascia less curved than preterminal fascia, metallic silver; cilia ivory and pale dark gray. Hindwing elongate-ovate, pale dark brown, with a darker apical area; apex rather acute; cilia ivory, subbasal line dark brown.
Abdomen: ivory and dark brown.
Male genitalia (Figs. 4). Uncus narrow, apex bifurcate and with spines on top, setaceous. Socius drooped and setaceous. Gnathos sclerotized partly. Tuba analis shorter than uncus and membranous. Tegumen long-trapezoidal. Valva flattened, broad, not folded at middle. Cucullus narrower than sacculus, apex rounded and setaceous, spined, along ventral margin, in a row on basal costa. Sacculus with a patch of short, small spines on middle of sacculus; short and stout spines grouped on angular part. Phallus about as long as cucullus, split apically into a pair of mittensshaped processes.
Female. Unknown.
Distribution. Korea (GG, GW, JN).
Host plant. Unknown
Remarks. This species is very similar to O. captiosana (Falkovitsh, 1960) and O. subtilana (Falkovitsh, 1959), and the three forms a tight species group.
Etymology. This specific name is derived from the Latin, “oculatus” meaning “eye-shaped”, referring to ocellus markings on the forewing.
