It is a member of the Graphium policenes-clade (policenes, Graphium liponesco, Graphium biokoensis, Graphium policenoides, Graphium porthaon.)

Aurivillius in Seitz places porthaon, policenes,sisenna (polistratus), polistratus, junodi, nigrescens (policenoides) and collona in the Policenes Group Subgroup 2 circumscribed Hindwing with a long, narrow tail of uniform width at vein 4. Frons black with white lateral margins. Wings above with green or greenish white markings. Cell of the forewing with 5 — 6 transverse bands or spots. Both wings with submarginal spots. Hindwing beneath with a so-called ornamental band, formed of red spots. Besides the markings already mentioned the forewing has a spot at the base of cellules 1 a and 1 b, an oblique transverse streak in the basal part of these cellules and 8 discal spots, one each in cellules 1 a — 6 and 8; the hindwing has a narrow transverse band at the base, a narrow median band which consists only of three spots (in the cell and in cellules 2 and 7) and usually also 7 discal spots in cellules 1 c -7, of 'which, however, that in 1 c is red. The larva has four pairs of spines, one pair each on the 1., 2., 3. and penultimate segments. The pupa is very angularly widened at the beginning of the abdomen and has a long hump on the mesothorax.
