Type species: Asura crustata Talbot, 1926 .

Etymology. The generic name is a combination of the Latin word ‘dispar’ meaning ‘unpaired’ and the generic name Barsine . The name refers to the sexual dimorphism of the genus. Gender feminine.

Diagnosis. Small moths with orange colouration, blackish pattern and slightly expressed sexual dimorphism: males have the forewing costa being wavy deformed and having a longitudinal row of androconial scales in the cell. In addition, in males the forewing pattern is reduced. Antennae of both sexes are ciliate. In the male genitalia, the valva is curved, blade-shaped, solid, without distal costal and distal saccular processes, similar to valvae of the genera Tumicla and the recently described Parvuspina , but also has the medial costal process being narrow, stick-like and situated subbasally, and the very small denticle-like medial saccular process. Such a combination of valva features is unique for the generic complex. The aedeagus is large, straight; the vesica structure is unspecific and is similar to that of Ammatho : it has several short diverticula ornamented with fields of various sized granulation and a cluster of short, stout, various sized cornuti medially. The female genitalia are characterised by the combination of the following features: (1) the antrum is present, has a deep medial concavity and is strongly connected to the 7 th abdominal sternite; (2) the ductus bursae is dorso-ventrally flattened and evenly sclerotised; (3) the corpus bursae is broad, strongly spinulose scobinated; (4) the appendix bursae is small, conical, situated postero-dorsally and directed posteriorly. The female genitalia of Disparsine are similar to those of Albarrania , but in the latter genus the antrum is connected to the 7 th sternite by a membrane, and the appendix bursae is larger and more heavily sclerotised.

Distribution. The genus is widespread in Sundaland and Sulawesi Island.

Number of species. The genus comprises two valid species.
