). Rufous brown. Forewing with a medial fuscous line outwardly oblique from costa to vein Cu2, slightly indented in cell, at Cu2 rounded inwardly to meet inner margin; a dark streak on discocellular; a postmedial fuscous line, inwardly oblique from radial veins; inner area of antemedial and outer area of postmedial lines bordered with ochreous scales; a broad fuscous band beyond postmedial line, veins on it paler; inner area dark brownish; a fine marginal line, cilia brownish; underside rufous with inner area ochreous.

): uncus hooded with baso-lateral flaps; gnathos curved distally, tip pointed and hooked, broadened below tip; valva simple; transtilla broad and curved distally; juxta broad at base, mediolateral area constricted, bifid apically: both arms (spikes) bearing small spines; vinculum U-shaped; aedeagus apex with multiple rows of small spines; base of vesica densely scobinated and the scobination gradually becomes sparse towards distal end.
Diagnosis.
Sacada dzonguensis
sp. nov. is most similar to
S. inordinata
(Fig.
9
), but the forewing has the antemedial and postmedial lines clearly separated, and there is a broad fuscous band beyond the postmedial line, whereas in
S. inordinata
both lines are fused from vein Cu2 to the inner margin, and the postmedial fuscous band is absent (but with traces of ferruginous).
Type material.
Holotype, male. India, Sikkim: Dzongu, 28.iv.2014, leg. R. Ranjan (Coll. NZC ZSI).
Etymology.
The species is named after its type locality, Dzongu, Sikkim, India.
