Taxonomy

In the original description (C. Felder & R. Felder, 1862; Wien. ent. Monats. 6 (1): 22) Papilio mencius Nob. is stated to be "geographica mutatio" [synonym of] P. alcinous Klug var. apud. [George Robert] Gray, 1852 Catal. of Lep. Ins. I Plate 4 fig. 2, 3. shown here in the taxobox illustration.

In other words, the variety of Papilio alcinous figured by Gray was raised to a "good" (one accepted) species by C. Felder and R. Felder. Their specimens were from the Chinese coastal trading city of Ningpo.
