Male: The upperside forewing is black with metallic, golden-green scales scattered over most of the wing excluding the outer and costal margins.

A metallic, golden-green median band starting from the costa passes outside the cell to just inside the tornus.

The upperside hindwing has a scalloped outer edge and a long, spatulate tail which may bear green scaling over the tips.

The underside is brownish black with a few golden scales scattered over all but the lighter coloured distal part.

Female: Slightly larger than the male, differing in the lack of a sex brand on the upperside of the forewing.
