Alpherakya sarta is a Palearctic species of lycaenid butterfly found in Afghanistan, Pakistan, Ghissar, Alai, Tian-Shan, Tarbagatai, Saur, South Altai and North India.

Dark brown, overlaid on both forewings and hindwings from the base outwards with bluish purple, this colour variable in extent but not reaching to the terminal margins in any specimens, and only up to or a little beyond the discs of the wings in very many.

In all specimens the immediate base of the wings is suffused more or less prominently with pale blue, which is continued for a short distance down the dorsal margin of the hindwing.

Forewing: a discocellular and a transverse discs; series of black spots, each spot encircled with white; the latter markings somewhat variable, in some specimens the discal aeries consists of five spots arranged in an outward curve, in others of six arranged in a transverse insinuate line; in nearly all specimens the edging of white on the outer side is spread diffusely outwards; beyond these there are in some specimens a subterminal inner and an outer maculated narrow transverse band, each band edged on the outer side narrowly and somewhat obscurely with white followed by an anteciliary slender black line; in other specimens the outer dark maculated band becomes a prominent, catenulate, terminal white band, each link centred with a dark spot.

Costa broadly, termen decreasingly from apex to tornus dark brown; rest of the wing dark shining yellow, suffused for about two thirds from base with light brown that leaves a transverse broad post discal band of the yellow ground colour prominently apparent, the inner margin of the broad, dark brown, terminal edging vandyked.
