Graphium (Pazala) glycerion Gray is considered by some as the correct nomenclature of this butterfly.

It has a related species, the sixbar swordtail Graphium eurous, which is also found in India.

Hindwing: a narrow black line from base along the dorsum, a broader black line along vein 1, joined below the cell by a broad black band that crosses the latter subbasally, a black patch on the produced posterior portion of the wing, studded at the tornal angle with two conspicuous yellow spots, below which there is a triangular white dorsal mark; the black patch with three somewhat obscure blue subterminal lunules; the tail narrowly edged with white; a narrow black medial line from costa that crosses near apex of cell and terminates on the median nervure; at the upper and lower ends of this are loops formed of slender black lines, in the female well marked, in the male seen only by transparency from the underside; finally, discal, postdiscal and subterminal slender black transverse lines from the costa terminate in the black anal patch.

However, the exact status and distribution of this butterfly are not well known and much work is needed on these aspects.

[2] These butterflies are found in open places in wooded country and, like the sixbar swordtail, prefer to inhabit favoured spots.
