Notes. (1) Moore (1878) described the species from the unspecified number of males. Subsequently Hampson (1900) cited only one male specimen as “Type”, which is a valid lectotype designation, according to the Article 74.5 of ICZN (1999). (2) The species greatly varies in its size, forewing width and the forewing pattern elements. In the male genitalia, the size of the medial process of the uncus, the size and shape of the lateral processes of the tegumen, the length of the distal costal process, and the length and width of the cornuti are also variable.

Diagnosis. The forewing length is 9.0– 10.5 mm in males and 10.0– 11.5 mm in females. Miltochrista terminata is superficially largely reminiscent of M. neoseriata and M. nuranang sp. nov. and the reliable identification requires the examination of the genitalia structures. In the male genital capsule, M. terminata is distinguished from M. nuranang sp. nov. by the apically pointed subuncal lobes, and the presence of triangular lateral processes of the tegumen. The phallus of M. terminata is medially upcurved whereas it is almost straight in the similar congener, and the vesica is somewhat broader. The female genitalia of M. terminata differ clearly from M. nuranang sp. nov. in the considerably shorter antrum with a basally narrower but markedly longer ventral crest, the slightly narrower postero-lateral subostial lobes, and the corpus bursae lacking the postero-lateral sclerotised protrusion.

Distribution. Northeast and South India (Meghalaya, Assam, and Tamil Nadu) ( Moore 1878), Myanmar (Kachin State and Mandalay Region) (new record), and Northern Thailand (Mae Hong Son Province) (new record).
