Rhodostrophia bisinuata Warren, 1895, Novit. zool., 2: 98. Holotype ♀, 'Japan' [incorrect locality], [possibly West China] (NHM). Rhodostrophia vinacearia sinensis Prout, 1913, in Seitz, Macrolepid. World, 4: 43. Holotype ♁, China: Moupin (NHM).

Diagnosis. The species is similar to R. reisseri sp. nov., but can be distinguished by the following characters: the colour of the wings varies from pale yellowish to brown, the medial bands of all wings are sometimes thin and without shadow; a blackish brown marking is usually present on vein M 1 between the postmedial line and the outer margin of the forewing. The genitalia are quite different from R. reisseri sp. nov.: the valva is long and with a quadrate apex; the terminal part of the sacculus is separate from the valva, and forms a long digitiform process; a short spinose process is raised from the cleft of the valva and the saccular process; the apex of the aedeagus is rounded with a tooth, the vesica is partly sclerotized and wrinkle; the male eighth sternite is widely concave on the posterior margin. In the female genitalia, the anterior part of the ductus bursae is much narrower than the posterior part; the signum is composed of two small vertical bars and weakly sclerotized; the seventh sternite is broad, concave on the posterior margin, and forms a pair of narrow and curved pouch-like lateral processes on the anterior margin.
