Tajuria cippus, the peacock royal,[1][2] is a species of lycaenid or blue butterfly found in the Indomalayan realm.

Forewing occasionally with a diseal series of faintly indicated black thin lunules, but in most examples these are obsolete, and the wing has no visible markings whatever.

Hindwing with a regular diseal series of similar marks rather closer to the margin than is usual, the upper marks forming the series more or less linear and well separated from each other, the last two are curved and turn in on to the abdominal margin a little above the anal angle, a sub-marginal pale grey band, another still paler and narrower band close to the margin; a black anal spot, with a small white spot on each side of its upper part, another and larger black spot in the first interspace, capped with orange, the space between them pale bluish-white with a few dark blue scales in it; terminal line of both wings dark brown.

Forewing darker towards the base, with a few brighter blue scales; the marginal bands blackish-brown, broader on the costa, but narrower at the apex than it is in the male.

Underside as in the male, but the discal series on both wings nearly always present.In Sri lanka these species are sometimes rare, because of the deforestation in some parts of the country.
