It may be a synonym of
Graphium mandarinus Collins & Morris. It is however treated as a
"good species" by Koiwaya. 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. ==References==
