Description. Head. Antenna about 2/5 length of forewing, bipectinate, tapering, length of longest ramus about five times diameter of male antennal shaft, rami shorter in female, length of longest ramus about four times diameter of female antennal shaft. Frons greyish white, rounded, not protruding, with pair of blackish brown dots medially. Labial palpus blackish brown, extending slightly beyond frons, second segment with hair-like scales. Vertex greyish green. Thorax. Dorsum greyish green. Patagium, tegula greyish green, blackish brown distally. Centre of tegula blackish brown. Posterior part of mesonotum with pair of black spots. Posterior margin of metanotum black. Two pairs hind tibia spurs in male, not dilated, without hair-pencil. Forewing: Length: male 26–28 mm; female 29–31 mm. Forewing outer margin weakly protruded, hindwing rounded. Wings greyish green, transverse lines blackish brown to black. Patterns of forewing: costa diffused with short longitudinal greyish brown flecks; antemedial, medial, postmedial, submarginal lines forming four black patches on costa; antemedial, medial lines indistinct, wavy, forming small black serrations on veins; postmedial line dentate, weak or invisible between veins, appearing as sharp black serrations on veins, broadened at inner margin; submarginal line appearing as series of small triangular patches between veins, distinct between M1 and M3, near costal, inner margins; two blackish brown patches between submarginal, terminal lines at veins M, anal angle; terminal line series of short strips between veins; fringes greyish white or green, darker between ends of veins; discal spot large, stellate, pale-centered, blackish brown ring rhomboid. Hindwing: with broad band between medial line and outer margin of discal spot brown, distinctly lighter than black discal spot ring; discal spot smaller than that of forewing; postmedial line more distinct than on forewing; submarginal line more continuous than that of forewing; terminal line, fringes similar to those of forewing. Venter yellowish grey; terminal band dark brown, broad, reaching outer margin; discal spot large, distinct, with thin central white line; costa of forewing pale yellowish brown, diffused with flecks. Abdomen. Pairs of black dorsal spots on first to sixth abdominal segments. Spots on first abdominal segment small, on second to the sixth segments relatively large, closer together. First abdominal segment pale grey, remaining segments yellowish green. Setal patch absent from third sternite of male abdomen. Eighth sternite of male abdomen with rounded cleft, apical processes round, weakly sclerotized. Male genitalia. Uncus rounded terminally, length equal to basal width, with pair of short lateral processes, about one-eighth length of uncus, acute distally. Gnathos with median process rounded terminally, equal to length of uncus. Valva broad medially, blunt terminally, length about three times as long as basal width; costa sclerotized, angled dorsally medially, expanded, bearing large area of long setae terminally; sacculus slightly curved; dorsal margin of sacculus broad, serrate, forming spinous process distally, extending beyond base of ampulla; ampulla, spinulose spur-like process. Saccus semicircular, about three-fifths length of basal width, with longitudinal arris apically in anterior half. Juxta sub-trapezoidal, anterior margin deeply concaved medially, longer than basal width. Coremata developed. Aedeagus with pair of small sclerotized spines posteriorly. Vesica without cornuti. Female genitalia. Ovipositor not strongly sclerotized, covered with dense setae. Lamella postvaginalis strongly sclerotized, curved posteriorly, with three lobes below, wrinkled anteriorly. Ductus bursae broad, weakly sclerotized, about two-fifths length of corpus bursae, colliculum short. Corpus bursae rounded, membranous; signum large, rounded, with fifteen to eighteen marginal spines and many small radially distributed central teeth.
Diagnosis. This species is hard to distinguish from O. cordularia on external and female genitalia characters. However, it differs in the following male genitalia characters: the lateral processes of the uncus are longer; the valva is expanded medially; the dorsal margin of the sacculus is broader; and the ampulla is spur-like, while in O. cordularia, it is triangular.
