Genus Disasuridia Fang, 1991

Disasuridia Fang, 1991 , Acta Entomologica Sinica 34 (3): 356, 360 (Type species: Disasuridia rubida Fang, 1991 , by original designation).

Diagnosis. Species of Disasuridia are externally reminiscent of the members of the genus Asuridia . However, male and female genitalia of the genus are unmistakable. The male genitalia of the genus are characterised by the following features: (1) the uncus is dorso-ventrally flattened, plate-like with a short pointed tip; (2) the tegumen bears short and dentate lateral subapical lobes (an autapomorphic feature; lateral lobes of tegumen are also present in Quadrasura Holloway, 2001 , but in the latter they are large and with smooth margins); (3) the posterior halves of the branches of the tegumen are dilated and fused; (4) the valva is short and broad, nearly elliptical; (5) the medial costal process is massive, triangular or thorn-like, its tip protrudes beyond the dorsal margin of sacculus; (6) the costa is heavily sclerotised and bearing a short and apically rounded distal process; (7) the sacculus is narrow but heavily sclerotised, with a serrulate dorsal surface; (8) the distal saccular process is absent, the distal section of sacculus is robust, curved dorsally and fused with the costa inwardly of the distal lobe; (9) the distal membranous lobe of the valva is small and separated from the sacculus and the costa; (10) the phallus is short and bearing two massive processes, of which the middle one is dentate (an autapomorphic feature); (11) the vesica is short, elliptical, with two clusters of tiny granbiculi. In the female genitalia, (1) the 7 th and 8 th abdominal sternites are fused; (2) the ostium bursae is narrow, opening in the middle of the 8 th sternite, and surrounded by broad sclerotised folds (an autapomorphic feature); (3) the corpus bursae is elliptical and bearing spinulose scobination, which is more robust posteriorly; (4) the signum bursae is present; and (5) the corpus bursae has a heavily sclerotised, triangular postero-lateral process.

Distribution. Species of the genus are known from the Himalaya, China, Indochina and the Greater Sunda Islands ( Indonesia: Java).
