Diagnosis. Adult (Figs 4–6, 21–23). Wingspan male 43–48 mm, female 45–48 mm. Somewhat smaller than O. iarbasalis Basically the structures of head are like in O. iarbasalis . Antennae of male less fasciculate and ciliated compared with O. iarbasalis . Palps of male extremely large, curved, extended over head; 3rd segment shorter than in O. iarbasalis , about half length of 2nd. Male palps covered with long greyish-brown hair-like scales (pale reddish-brown in O. iarbasalis ), their vesture shorter than in O. iarbasalis . Those of female large, approximately same size as in male, covered with short grey and white scales, tip of segments bordered with white. Head, tegulae and patagia greyish-brown, thorax dorsally covered with greyish-brown scales forming small thoracic crest. Abdomen covered with yellow-brownish scales, forming small crest. Male forewing with prominent angled costal extension in central part, smoother compared with O. iarbasalis . Wing colour ochre-brown with dark elements of wing pattern; wing maculation smoother than in O. iarbasalis ; in males antemedial field darker compared with O. iarbasalis antemedial line less distinct, waved; veins not outlined by pale brown as in O. iarbasalis ; postmedial line dentate (waved in O. iarbasalis ), subterminal line separated for angled streaks (as blackish dashes in O. iarbasalis ); hindwing with broader and paler brownish-yellow basal part compared with O. iarbasalis , with broad brown terminal terminal field and more curved subterminal band. Female forewing similar to that of O. iarbasalis but differs by more angled antemedial line with more clear white outline; hindwing differs by more angled subterminal line. Male genitalia. ( Fig. 38, 39 ). Compared with O. iarbasalis , all structures are much slender, subscaphium with broader terminal part, valva thinner and somewhat more curved; aedeagus vesica with broader scobinated patch medially. Female genitalia. ( Fig. 47, 48 ) Differ from O. iarbasalis by broader papillae anales, longer and stronger apophyses anteriores and posteriores, shorter funnel-like antrum, thinner and shorter ductus bursae and position of bulla behind joining of ductus with corpus bursae.

Distribution. Southwest China (Pov. Yunnan), North India ( Hindustan, Sikkim, Tamil Nadu), Nepal (Ganesh Himal), * Thailand (Phrae, Chiang Mai), * Laos, * Vietnam (Hoeng Lien Son). The species occurs in forested areas at elevation 500–1500 m. Flight period from March to September.

Material examined. MALAYSIA, BORNEO: 1 male, Prov. Sabah, Mount Kinabalu, 1600 m, Provera leg., 3.iv.1983, slide GB 12058 male, Ident No. BC ZSM Lep 58651 (AZ).

Diagnosis. Adult (Fig. 7, 28). Wingspan male 38 mm. Smaller than O. iarbasalis and O. lindsayi . Palps of male large but smaller than in the two these species, straight, 3rd segment small about 1/3 length of 2nd, covered with dense scales and hairs on inner surface. Patagia and tegulae brown-grey with whitish bordering, thorax brown-grey. Forewing without costal extension, relatively short and broad, with deep smooth dorsal excavation, unique within the genus. Ground colour of forewing blackish-brown; wing pattern formed by basal, ante- and post medial lines more expressed in costal field; medial field dark blackish brown, subterminal field brown, subterminal line waved. Hindwing yellowish basally, brown to terminal margin, with conspicuous rusty patch in subbasal area. Male genitalia. ( Fig. 40 ). The uncus and scaphium much longer than in O. iarbasalis and O. lindsayi ; uncus curved basally and subapically; juxta narrow, arrow-like; valva much broader than in O. iarbasalis and O. lindsayi , directed diagonally, slightly curved, somewhat extended and rounded apically. In aedeagus vesica with scobinated area basally and finely spined lobe centrally. Female genitalia. Not examined.

Distribution. Malaysia (Borneo, Sabah, Danum Valley), Brunei (Ulu Temburong National park). The species occurs in forested areas at elevation 500–1500 m. Flight period from January to April and from September to December.
