Tegula brown. Legs with long yellow to pale orange hairy scales, hind tibia with one pair of spurs. Wings: Forewing length 15.5–17.0 mm in male.

Wings brown, diffused with black scales, and indistinct slightly wavy reddish brown stripes; both wings with antemedial and postmedial lines invisible, discal spot small, white; discocellulars of forewing decorated with white speckles. Underside: yellowish brown, diffused with dark scales; a blackish brown oblique line from apex to hind margin present on forewing. Fringes brown. Male genitalia: uncus short, with broad and expanded base and pointed tip; socii obsolete; gnathos with median process developed, nearly triangular, with rounded tip; valva broad, completely divided into a large costal lobe and a small sacculus; costal lobe rounded, with costa well sclerotized and ventral margin straight; sacculus with pointed spinose process; saccus large and rounded; aedeagus well sclerotized, with four large pointed teeth posteriorly; some very small spine-like cornuti on vesica. Tergite 8 narrow, concave medially at posterior margin; sternite 8 wider and broadly concave medially at posterior margin. Female genitalia: unknown. Material examined. Holotype 3 (IZCAS), CHINA, Hainan: Wuzhishan, Shuiman, 732 m, 8–9.VII.2007, coll. Li Jing. Paratype: Hainan: 13 (IZCAS), Jianfeng, Tianchi, 900 m, 12.IV.1980, coll. Cai Rongquan. Diagnosis. O. inflativalva can be differentiated from other congeners by the lack of transverse lines on the upperside of both wings. The male genitalia are distinctive in that the costal lobe and the sacculus are totally separated, and the aedeagus bears four large teeth. Etymology. The species name is a combination of the Latin inflatus (inflated, swollen) with term valva, referring to the expanded valva.
