Upperside: both wings rather intense deep blue: primaries with the costa broadly, posterior margin more broadly, apex still more broadly black ; secondaries with the blue limited to just over the median area, the rest of the wings black. Tails two, black, the longer one white-tipped. Underside : both wings very dark greyish brown: primaries with an obscure dark dot near the centre of the cell and a small dash closing it, costa with three dark dots; transverse blackish line curved irregularly and scalloped from the costa to the submedian nervure, a submarginal row of blackish dots, margin obscurely dark, internal area quite pale: secondaries with a small white spot about one-third along the costal nervure, below which is an obscure dark short dash in the cell; from two-thirds along the costa to the middle of the abdominal margin is a narrow, indefinite, obscure band of dark shading edged externally and sharply with white, a submarginal row of dark spots forming an almost lunular line; on each side of the long tail is a slight grey scaling.

Upperside: both wings entirely dark brown. Underside as in the male, but decidedly paler.— Bethune-Baker, ''A Revision of the Amblypodia Group of Butterflies of the Family Lycaenidae''
