Diagnosis. The forewing length is 10.0– 10.5 mm in males and 12.0 mm in females. Miltochrista jatinga sp. nov. is superficially reminiscent of M. neoseriata but can be distinguished from it by the thicker longitudinal streaks and the medial line of the forewing, and the larger discal spot. However, in the genitalia of both sexes, the new species is similar to the partially sympatric M. zinchenkoi ( Figs 51–53 View FIGURES 48–61 ), from which M. jatinga sp. nov. is superficially differs in the narrower forewing, the longer longitudinal streaks in the ante- and postmedial areas, the oblique and less posteriorly curved medial line which is medially almost perpendicular the forewing axis in M. zinchenkoi , and the smaller discal spot well-separated from the medial line (it is almost touching the line in the congener). In the male genital capsule, M. jatinga sp. nov. is distinguished from M. zinchenkoi ( Figs 118 View FIGURES 115–118 , 119 View FIGURES 119–122 ) by the proximally narrower valva with a longer valvula, the triangular and apically pointed distal costal process (it is rounded in the congener), and the smoothly upcurved distal saccular process whereas it is upcurved at an almost right angle in M. zinchenkoi . In the phallus, the new species has a more downcurved coecum in comparison to the similar congener. The vesicae of the two species are similar but in M. jatinga sp. nov., the subapical cornutus is slightly thinner than in M. zinchenkoi . The female genitalia of the new species differ from M. zinchenkoi ( Fig. 144 View FIGURES 143–146 ) in the anteriorly broader ductus bursae, and the broader corpus bursae bearing thinner and more numerous spines along the inner margin of the postero-lateral sclerotised plate. Additionally, the lateral pockets of the 7 th sternite of the new species are broader than in M. zinchenkoi and are apically almost semicircular whereas they are bearing narrow triangular protrusions in the aforementioned congener.

Distribution. The new species is known from Northeast India (Assam, Mizoram and Meghalaya), west Myanmar (Chin State) and Northern Thailand (Chiang Mai Province).

Etymology. The specific epithet is homonymic of the type locality. The name is a noun in nominative singular in apposition.
