Race "decoratus" is found in the Andaman and Nicobar islands and is very similar to the typical form, from which it can be distinguished as follows: Upperside green spots smaller, especially the discal series on the forewing. Underside hindwing: the red postcostal spot is relatively small but the red part has much increased against the black part; besides the large red anal mark and the mark before the first disco-cellular veinlet, there is a large red spot in the lower median cellule (interspace 2), a smaller red spot in each of the three preceding cellules (interspaces 3, 4, 5) and a streak-like spot at the base of the lower median cellule.
