Note. Moore (1877) described the species without the sex and number of specimens being mentioned. In order to stabilise the nomenclature, the female syntype labelled as “Type” and preserved in NHMUK is hereby designated as the lectotype.
Diagnosis. The forewing length is 6.5–7.5 mm in males and 7.0–8.0 mm in females. Miltochrista andamana is readily distinct from the other members of the species-group due to its ochreous forewing ground colour (it is yellow in the related congeners), the medial line medially convex outwards, and the shorter dashes of the postmedial line touching each other. The male genital capsule of the species is similar to M. quadrata but is distinguished by the considerably shorter and medially narrower uncus, the longer vinculum, and the somewhat broader valva with a shorter and narrower distal section of the valva having a more rounded dorsal corner. The phallus of M. andamana is shorter and narrower than in the similar congener, and with a markedly more elongate, thumb-shaped coecum. Compared to M. quadrata, the vesica of the current species is broader (in proportion to the genital capsule size), having a narrower and conical terminal diverticulum (it is semiglobular in the congener), and bearing three cornuti (vs. two cornuti in M. quadrata). In the female genitalia, M. andamana differs from M. quadrata in the somewhat shorter antrum, and the smaller spines in the posterior clusters in the corpus bursae.
Distribution. Endemic to the Andaman Archipelago (India) (Moore 1877).
