Parnassius charltonius Gray,  – Regal Apollo
Subspecies in India:
Considerable infrasubspecific and subspecific variation in this species has been named, often with little understanding of geographical and altitudinal separation between the named forms or subspecies, so it is difficult to ascertain taxonomic validity of many of these names. A comprehensive study of this entire genus is in order before any taxonomic issues can be solved in this group.
