Taxonomy

It may be a synonym of Graphium mandarinus Collins & Morris.^[4] It is however treated as a "good species" by Koiwaya.^[5] A further problem is that the name glycerion is permanently invalid as a junior primary homonym of Papilio glycerion Borkhausen, 1788.

Graphium glycerion is very little known and as with Graphium mandarinus, G. tamerlanus, G. phidias and G. olbrechtsi few specimens exist.
