Arhopala labuana , is a butterfly in the family Lycaenidae. It was described by George Thomas Bethune-Baker in 1896. It is found in the Indomalayan realm (Burma, Peninsular Malaya, Sumatra, Pagi, and Borneo).[1] [2]
The upper surface in the male is lighter, the blue colour is more of an ultramarine than violet tint [than in related species]. Beneath similar to dohertyi, the transverse bands in the forewing straighter and more regular, in the hindwing, however, more interrupted than in dohertyi. The female is above of a very bright blue with a broad (4.5 mm.) black, more distinctly defined distal band.[3]
