Review of the genus Cidariplura Butler, 1879 (Lepidoptera, Erebidae, Herminiinae) in Taiwan with descriptions of four new species

The genus Cidariplura Butler, 1879 from Taiwan is reviewed. A total of seven species are confirmed to occur in this old landbridge island, and four new species are described: C. shanmeii Wu & Owada sp. nov., C. maraho Wu & Owada sp. nov., C. atayal Wu & Owada sp. nov. and C. ilana Wu & Owada sp. nov. The Taiwanese C. bilineata (Wileman & South, 1919) is superficially similar to the Indian and Nepalese C. brevivittalis (Moore, 1867) but their genitalia show distinct differences. Elyra albifascia Hampson 1929 is regarded as a junior synonym of C. brevivittalis (syn. nov.). All diagnostic characteristics of Cidariplura from Taiwan and its adjacent areas are illustrated.
