Two new species of the genus Acrolepiopsis Gaedike, 1970 (Lepidoptera, Glyphipterigidae) from Korea

The family Glyphipterigidae comprises small-sized moths with a wingspan ranging from 8 to 14 mm. This family is mainly distributed in the Palaearctic and Oriental Regions. In Korea, five species of the genus Acrolepiopsis Gaedike, 1970 have been recorded. However, species-level identification within this genus is often challenging due to high morphological similarity amongst species. In this study, two new species of the genus Acrolepiopsis, A. quinquelobatae sp. nov. and A. koreana sp. nov., are described from Korea. Species delimitation is supported by COI gene analysis and morphological characteristics of genitalia, both of which reveal clear genetic divergence from other Acrolepiopsis species previously recorded in Korea. Photographs of adults and genitalia, along with information on host plants, are also provided.
