Description
Male upperside forewings have a black ground colour glossed blue. There is a discal arc of five or so spots and a postdiscal sinuous line of eight to ten spots. These spots are light blue and slightly metallic. The margin has pale amorphous lunules. The hindwing has two postdiscal rows of the light blue spots, the second close to the margin which has pale more lineate lunules. There are two short tails.

The female upperside has light brown basal areas, more extensive on the hindwing. There is a discal band of white marks just inside the much darker distal part of the forewing and two apical white spots. On the hindwing the dark area is narrow has seven or so light blue and slightly metallic spots with some white scales. There are pale marginal lunules and one long and one short tail.

The underside wings are variously light brown with black pattern lines and in the female only a white discal band.
