Diagnosis. Externally three subspecies of O. hoenei can be differentiated by the degree of the falcate forewing apex and the protrusion of the hind wing outer margin. In O. hoenei tienia, the forewing apex is most strongly falcate, and the outer margin of the hind wing protrudes more strongly than in the other two subspecies. The outer margin of the forewing in O. hoenei hoenei is more convex than in O. hoenei inangulata, but less so than in O. hoenei tienia. In the male genitalia, the leaf-like sacculus is more developed in O. hoenei hoenei, a little narrower in O. hoenei inangulata, and smaller in O. hoenei tienia.

Distribution. China (Heilongjiang, Shanxi, Henan, Shaanxi, Ningxia, Gansu).

Remarks. In the original description of O. trianga Chu & Wang (1987) the figured male genitalia belongs to Spectroreta hyalodisca rather than to the type specimen of O. trianga. We refer the holotype of O. trianga to O. hoenei hoenei, and the paratype to O. loochooana.
