Note. Moore (1878) described the species from the unspecified number of specimens of both sexes. In order to stabilise the nomenclature, the single female syntype labelled as “Type” located in NHMUK is hereby designated as the lectotype. Diagnosis. The forewing length is 13.0 mm in males and 14.5 mm in females. Miltochrista discistriga is similar to M. neoseriata in its forewing markings but distinguished by its larger size. The male genital capsule of the species is clearly different from other similar congeners in the shorter uncus, the relatively short and claw-shaped, and dorsally directed distal costal process, the broad valvula, and the narrow but heavily sclerotised and upcurved distal saccular process. The vesica structure of M. discistriga is similar to those of such species as M. neoseriata, M. aureata, M. mawphlang sp. nov. and M. kravchenkoi but differs in the markedly longer cornuti. The female genitalia of M. discistriga are most reminiscent of M. neoseriata but are distinct due to the shorter and narrower ductus bursae with a sinuous ventral margin of the ostium, and the broader corpus bursae with a narrower but more heavily sclerotised postero-lateral sclerotised area edged with smaller spines and lacking a cluster of denticles at the junction with the ductus bursae. Additionally, the lateral sclerotised plates of the 7 th sternite of M. discistriga are shorter and more weakly sclerotised than in M. neoseriata, and their lateral pockets are vestigial. Distribution. The species is currently known from South, North and Northeast India (Tamil Nadu, Uttarakhand, West Bengal, Sikkim, and Arunachal Pradesh).
