Forewing distinctly expanding terminally, broad in distal part, with costa slightly concave medially; termen oblique, somewhat convex. Ground-color clear white, in form of broad blotch extending from mid-costa to before apex, reaching beyond middle breadth of wing, with arched distal edge. Dorsal half of wing suffused grey; apical area dark grey with blackish reticulation and some whitish spots; base of wing brownish-grey with some black dashes; median fascia ill-defined, diffuse, blackish, darkest in costal half. Fringes whitish, with median line grey and divisions situated beyond black terminal dots blackish. Hindwing white-cream, suffused and stigulated brownish grey on periphery; fringes long, cream; greyish median line only at apex.
Male genitalia: Socii fairly long, on rather short base; valva up-curved; sacculus with long, rounded free termination; median part of transtilla fairly long, with distinct apical bifurcation. Aedeagus slender, bent, with moderate terminal prominence; caulis very large, with protruding, spined lateral projections; cornutus as long as median part of transtilla.

Comments. Closely related to walkerana but easily distinguished by more black pattern and white blotch of ground colour at forewing costa. As regards genitalia, the new species differs in having the rounded end of the sacculus, larger aedeagus and very large, spined caulis.[2]
