Genus Barsaurea Volynkin & Huang, 2019

Barsaurea Volynkin & Huang, in Volynkin, Huang & Ivanova, 2019 , Ecologica Montenegrina 26: 65 (Type species: Miltochrista phaeoxanthia Hampson, 1900 , by original designation).

Diagnosis. Small moths with narrow and elongated forewing, golden colouration and brown diffuse pattern. Males have a narrow longitudinal field of androconial scales along the forewing costa between the veins R 1 and R 3. The male genitalia are characterised by the combination of the following features: (1) the massive, laterally flattened and setose uncus; (2) the presence of an androconial gland in inner membrane of vinculum (an autapomorphic feature); (3) the presence of a round setose lobe in the medial section of costa (an autapomorphic feature); (4) the absence of a distal membranous lobe of valva; (5) the narrowed valva apex with one or two apical processes; (6) the short sacculus without a distal process; and (7) the aedeagus vesica having elongated diverticula bearing series and small bunches of various sized thin but long spines. The female genitalia of Barsaurea are characterised by the combination of the following features: (1) the very broad, rectangular papillae anales; (2) the sclerotised, dorso-ventrally flattened and narrowed posteriorly ductus bursae; (3) the narrow posterior section of corpus bursae with the larger sack-like left and the smaller pocket-like right sclerotised protrusions (an autapomorphic feature); (4) the large elliptical membranous anterior section of corpus bursae; (5) the small elliptical and heavily sclerotised appendix bursae having an extremely large sack-like bulla, which is weakly setose basally and membranous distally, and connected with the appendix bursae by the narrow membranous tube (an autapomorphic feature).

Distribution. The genus is widespread from northeastern India through southwestern China and Indochina to Malay Peninsula and Sumatra Island.
