Diagnosis. Small moths with reddish or yellow coloration and thin black pattern. Members of Disasuridia are small moths being very similar superficially to members of the genus Asuridia . However, male and female genitalia of the genus are unmistakably recognisable. For the male genitalia the following features are characteristic: (1) the uncus is plate-like, dorso-ventrally flattened, with a short pointed tip; (2) the tegumen with short dentate lateral subapical lobes (an autapomorphic feature; lateral lobes of tegumen are also present in Quadrasura , but in Quadrasura they are very large and not dentate); (3) the apical half of tegumen fused, broad; (4) the valva is short and broad, nearly elliptical; (5) the medial costal process is massive, trigonal or thorn-like, its tip protrudes beyond the dorsal margin of sacculus; (6) the costa is heavily sclerotised, distal costal process is present, short, with a blunt tip; (7) the sacculus is narrow but heavily sclerotised, its dorsal surface is serrulate; (8) the distal saccular process is absent, the distal section of sacculus is robust, curved dorsad and fused with the costa inwardly of the distal lobe; (9) the distal membranous lobe of valva is present, small, well separated from the sacculus and costa; (10) the aedeagus short, with two massive processes, of which the middle one is dentate (an autapomorphic feature); (11) the aedeagus vesica is short, elliptical, with two fields of weak granulation only. In the female genitalia, (1) the 7 th and 8 th sternites are fused; (2) the ostium bursae is narrow, situated at middle of the 8 th sternite and is surrounded by four broad folds (an autapomorphic feature); (3) corpus bursae elliptical, with strong spinulose scobination, which is more robust posteriorly; (4) signum bursae is present; (5) the corpus bursae has a poster-lateral heavily sclerotised trigonal lateral process; such processes are known from the genus Chrysasura and some members of the genus Afrasura only.

Distribution. Nepal, northern and northeastern India, China and northern Indochina.

Number of species. The genus comprises seven valid species.
