Diagnosis. Eupeocilia jakarana is a large species closely related to E. crocina Razowski, 1968, distributed in the western part of the Himalaya, and E. cracens Diakonoff, 1982 from Sri Lanka. Externally, it is very similar to E. ambiguella (Hübner, 1796), but it has a greater forewing length. The genitalia are similar to those of E. crocina but can be distinguished by the following features: socii slenderer, top of the transtilla concave, and cornutus stronger.

Fringe concolourous with apical part of wing. Hindwing dirty white towards apex with scattered black brown dots, fringe concolourous. Abdomen: Genitalia (Fig. 33–34) with socii long, slender, rounded dorsally; transtilla subtriangular, top concave dorsally, with some thorns.
