Description.

Male, wingspan 30 mm (Fig. 11 ). Rufous brown. Forewing with a sinuous medial fuscous line outwardly oblique from costa to vein Cu2, then broadly and inwardly rounded to meet inner margin; a band of paler scales on discocellular; postmedial fuscous line, slightly curved, inwardly oblique from costa to inner margin; inner area of medial line and outer area of postmedial line bordered with ochreous scales; a broad ferruginous band beyond postmedial line; a fine marginal line, cilia brownish; underside rufous with inner area ochreous. Hindwing pale fuscous with rufous tinge; traces of diffused, postmedial fuscous line; a fine marginal line present; underside rufous. Male genitalia (Figs 29 , 30 ): uncus hooded with baso-lateral flaps; gnathos curved distally, hooked, tip pointed, broadened before tip; valva simple; transtilla broad with two apical, small thumb-like processes; juxta narrow, mediolateral area constricted, bifid apically with both the arms bearing spikes; vinculum U-shaped; aedeagus apex with single row of small spines; base of vesica densely scobinated and the scobination gradually becomes sparse towards apex.

Diagnosis.

Sacada umtasorensis sp. nov., distributed in Meghalaya is most closely similar to its allopatric relative S. dzonguensis sp. nov., (distributed in Sikkim) (Fig. 10 ), but it is distinct by the oblique postmedial line from costa to inner margin, whereas in S. dzonguensis , the postmedial line is straight from the costa to the radial vein and then oblique to the inner margin. In the male genitalia of S. umtasorensis (Figs 29 , 30 ), the juxta is narrow with the two apical lobes exhibiting more spines, and the aedeagus apex has a single row of small spines, whereas in S. dzonguensis (Figs 27 , 28 ), the juxta is broad, the apical lobes have fewer spines, and the aedeagus apex exhibits multiple rows of small spines.
