Diagnosis. Compared to other congeneric Chinese species, O. shania has a much narrower brown medial shade interior to the postmedial line on the forewing. O. shania , together with O. loochooana , and O. pulchripes has a round black subtornal patch on the fore wing hind margin. However, the forewing colour inside the oblique postmedial fascia is yellow in O. shania but reddish brown to brown in the other two species; the hind wing outer margin is evenly convex in O. shania and O. loochooana , but sinuous in O. pulchripes . The male genitalia of O. shania are similar to those of O. pulchripes in the expanded and tapering uncus base, the very slender median process of the gnathos, the broad and rounded valva, the sacculus with strongly sclerotized process, and the unmodified saccus. But they differ by following characters: the distal part of the uncus is much narrower and more pointed in O. shania but blunt in O. pulchripes ; the median process of the gnathos is much longer in O. shania than in O. pulchripes ; the sacculus bears a large broad sclerite with margin decorated with small pointed teeth in O. shania , but a long hooked and smooth process in O. pulchripes ; the aedeagus is gradually and slightly sclerotized towards the posterior, without a distinct cornutus in O. shania , but well sclerotized and with two cornuti in O. pulchripes . The lateral processes on the posterior margin of sternite 8 are narrow in O. shania but very broad and flat in O. pulchripes .

Distribution. China (Zhejiang, Fujian, Sichuan).

Remarks. Chu & Wang (1987) described O. bimaculata and O. cera , both from Mt. Wuyi, Fujian. We find these two species identical to O. shania on both external and genital characters, and therefore synonymize them here.
