It is very easily distinguishable from its similar species simply because it is the smallest. The uppersides of the wings of both sexes are dark grey brown to slate. It lacks the obvious brightest blue, which is only visible in an oblique light. The upper surface on the underside hindwing, the central band is more separated from the outer band than in any other species, making the yellow area much wider and a distinctive feature.
In some the upperside forewing orange bands are either weak or absent. The hindwing is bordered with a similar streak along the termen. The upperside of the forewing has bands which are reddish orange. The 3rd is bifurcate but long and the 4th has two silver spots.

It is similar as the male. There is a long orange marginal band on the upperside of the hindwing which is easily distinguishable from its similar species.

Food plants
The larvae feed on jujube, Zizyphus rugosa, Lxora longifolia, Clerodendrum siphomanthus, C. inerme, Allophylus cobbe, Ixora chinensis and Canthium parviflorum.
