Type species: Miltochrista dentifascia Hampson, 1894 .

Etymology. The generic name is a combination of the Sir George Hampson’s surname, who is an author of its type species, and the type species name dentifascia . Gender feminine.

Diagnosis. Small moths with reddish colouration and blackish ‘miltochristoid’ pattern. Antennae of both sexes are ciliate. The male genital capsule of Hampsonascia is similar to that of Miltochrista , by the well-developed distal costal and saccular processes and the distal membranous lobe as well, but differ by the presence of a very small, denticle-like medial costal process. The autapomorphic feature of the male genitalia of Hampsonascia is the vesica structure, which has several very long and narrow granulated diverticula which are usually almost impossible to evert. The autapomorphic feature of the female genitalia is the extremely long, narrow and hook-like curved anteriorly appendix bursae with spinulose scobination inwardly, which corresponds to the long diverticula of male aedeagus vesica. In addition, the female genitalia of Hampsonascia are characterised by (1) the presence of a rugose antevaginal plate having two broadened lateral lobes; (2) the relatively broad ductus bursae being dorso-ventrally flattened and evenly sclerotised; and (3) the corpus bursae being conspicuously shorter than the appendix bursae and having several fields of various sized spinules.

Distribution. Northeastern India, southern China and northern Indochina.

Number of species. The genus is monobasic.
