Arhopala belphoebe is a butterfly in the family Lycaenidae. It was described by William Doherty in 1889. It is found in the Indomalayan realm (Assam and Peninsular Malaya). The subspecies A. b. cowani <small>Corbet, 1941</small> is described from Malaya.
It was described from a bad specimen; the whole proximal portion of the hindwing, as well as the forewing are violettish blue. Under surface pale brown, with a violet gloss, nearly all the markings composed of ring-shaped circles filled with a slightly darker colour. A somewhat doubtful species which is compared with agesias in the original description, though other authors do not find any resemblance.
