Type species: Asura horishanella Matsumura, 1927 .

Etymology. The genus name is a combination of the surname Matsumura, an author of the type species, and the generic name Barsine . Gender feminine.

Diagnosis. Small moths with red colouration and dark grey forewing pattern and diffuse yellow spots. Antennae of both sexes are ciliate. In the male genital capsule, the anellus is weakly sclerotised, valva is strongly narrowed apically, the medial costal process is robust, the costa is not reaching the valva apex, the distal lobe of valva small, the distal saccular process is robust. The main autapomorphic feature in male genitalia is the valva costa structure: in Matsumursine , the costa has two processes medially: the medial one directed ventrally (the feature common for the generic complex) and the dorsal one, which is broad, short, swollen and weakly sclerotised in the type species and robust and thorn-like but situated more basally in M. speciosa . The aedeagus is narrow, with an elongated coecum and a short thorn-like carinal process. Aedeagus vesica short, nearly globular, with cluster of very small spinules or spine-like cornuti. In the female genitalia, the combination of the following features is characteristic for the genus: (1) the postvaginal plate is present, strongly broadened (similar to that of Ammatho (Delineatia) , but much longer and broader); (2) the ductus bursae is asymmetrical, curved laterally, its long and protruding right side is heavily sclerotised, while the left side is very short and weakly sclerotised (autapomorphic feature; similar asymmetrical ductus bursae is known in Barsura only, but in the latter genus it is longer and not curved, and is combined with broad sclerotisation and scobination of corpus bursae, whereas in Matsumursine the corpus bursae is membranous with weak granulation only); (3) posterior section of corpus bursae narrow, twisted, membranous; (4) anterior section of corpus bursae is broadened, sack-like, membranous, with a field of very weak granulation and a small signum; (5) appendix bursae is narrow, finger-like, membranous, situated postero-laterally.

Distribution. Mainland China and Taiwan Island.

Number of species. The genus comprises two valid species.
