On wing pattern, O. liensis is close to O. trispina except for the evenly convex hind wing outer margin and the distinct black subtornal patch on the forewing. The male genitalia are close to those of O. sanguinea in that the uncus is broad and rounded, the median process of the gnathos is straight, the valva is broad and round, bearing a reversely pointed terminal process, the sacculus has a long process, the saccus is broad, with anterior margin truncate, and the aedeagus has posterior part in the form of a process. The main differences in the male genitalia between these two species are: the length of the sacculus, which is shorter in O. sanguinea but longer in O. liensis ; the median process of the gnathos, which is narrower and pointed in O. liensis but broader and blunt in O. sanguinea ; the saccus, which is more quadrate in O. sanguinea . In addition, the posterior margin of sternite 8 is flat in O. sanguinea but medially concave in O. liensis . The female genitalia lack a signum in both species.The female genitalia of O. liensis are illustrated and described here for the first time: the posterior apophyses are very short, and the anterior apophyses are long. The ostium bears lateral opercular structures. The wide ductus bursae is extremely short, and the corpus is broad, without signum. Distribution. China (Heilongjiang, Hubei, Fujian, Sichuan, Yunnan).
