Diagnosis. The wing pattern resembles the brown form of O. paki , which is externally indistinguishable. Two species can be differentiated by the male genitalia. In O. turpis , the uncus is broader, the valva shorter, and the long sacculus smooth and without teeth, while in O. paki , the uncus is narrower, the valva longer, and the long sacculus bears two small teeth. The aedeagus of O. turpis bears a twisted and protruding sclerite, which is a developed dorsal sclerite in O. paki . The median process of the gnathos in O. turpis is much longer, the length being about two-thirds that of the sacculus, while in O. paki it is much shorter, with length less than half the length of the sacculus. In the female genitalia, the signum is situated more basally than in O. paki . Distribution. China (Shandong), Japan, Korea.
