Material examined. CHINA, Sichuan ( IZCAS): Qingchengshan, 4.VI.1979, coll. Gao Ping, 13. Tibet ( IZCAS): Bomi, Yigong, 2300 m, 27–30.VIII.1983, coll. Han Yinheng, 23; Mêdog, Hanmi, 2095 m, 10–11.VIII.2006, coll. Lang Songyun, 23.

Diagnosis. Oreta ancora shares the following features with O. flavobrunnea : a dark brown elongate hook on the forewing apex, a yellow oblique line from forewing apex to hind margin, small white-line speckles on cell margins, the expanded uncus, the slender digitate median process of the gnathos, the long and broad valva, the forked sclerotized process on the sacculus. However, O. ancora can be distinguished by the following characters: the forewing apex is more falcate; the outer margin under the apex does not distinctly protrude as in O. flavobrunnea ; a black tornal patch is present on the forewing of O. ancora but absent in O. flavobrunnea . In the male genitalia, the valva bears two hooked and pointed teeth distally in O. flavobrunnea which are absent in O. ancora ; the margin between the two forks on the sacculus is decorated with a row of teeth in O. ancora but smooth in O. flavobrunnea ; the saccus is much broader in O. ancora than in O. flavobrunnea . The posterior part of the aedeagus is tapering and pointed in O. flavobrunnea , but rounded and bearing a pointed tooth in O. ancora .

Distribution. China (Sichuan, Tibet), Nepal.
