FF5487B59D1EFFF9FF37F8BEFF6680B6.taxon	diagnosis	Diagnosis. Species of Ashibusa are similar to those of Stathmopodinae in Stathmopodidae in the hind tibiae with whorls of bristles and the adults erecting hindlegs at rest. Species of Ashibusa can be distinguished by the shape of the head, the labial palpi and the forewings, and the strongly asymmetrical male genitalia (Zhang & Li, 2009: 335).	en	Zhang, Di, Li, Houhun (2023): A taxonomic review of the genus Ashibusa Matsumura, 1931 (Lepidoptera: Cosmopterigidae) from China.

FF5487B59D13FFF6FF37FE54FD4D86A4.taxon	diagnosis	Diagnosis. The new species is similar to A. lativalvula Zhang et Li, 2009 superficially. It can be distinguished by the forewings without a white speckle between the fold and the dorsum; in the male genitalia by the right brachium produced inward medially, the dorsal process 1 / 6 the length of the right brachium, and distal 1 / 3 of the valvae expanded elliptically; and in the female genitalia by the subrectangular corpus bursae. In A. lativalvula, the forewings have a pale yellowish white speckle between the fold and the dorsum (Zhang et Li, 2009: 337, fig. 4); the right brachium is not produced medially, the relatively longer dorsal process is 1 / 5 the length of the right brachium, and the distal 1 / 3 of the valvae is expanded rectangularly (Zhang et Li, 2009: 338, fig. 10); and the corpus bursae is elliptical. The species resembles A. ledongensis sp. nov. in the male genitalia, and the differences between them are stated in the diagnosis of the latter species.	en	Zhang, Di, Li, Houhun (2023): A taxonomic review of the genus Ashibusa Matsumura, 1931 (Lepidoptera: Cosmopterigidae) from China.
