Graphium glycerion, the spectacle swordtail, is a species of butterfly found in the Indomalayan realm (northern India, China, Thailand, Laos and northern Vietnam). The species was first described by George Robert Gray in 1831.
Subspecies G. g glycerion (Nepal, Sikkim, Assam) G. g. caschmirensis (Rothschild, 1895) (north-western India) G. g. kimurai Murayama, 1982 (northern Thailand) G. g. phangana (Okano, 1986) (northern Thailand)
Taxonomy It may be a synonym of Graphium mandarinus Collins & Morris. It is however treated as a "good species" by Koiwaya.Koiwaya, S. (1993) Descriptions of Three New Genera, Eleven New Species and Seven New Subspecies of Butterflies from China. Studies of Chinese Butterflies. 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.
