This is clearly an error.  If machaon is the TS of Papilio, and Papilio is
older than Princeps, then machaon and any properly included subspecies
belong in Papilio (s.s.).  It's possible that species originally described
as subspecies of some other name could be found to belong to a different
genus group taxon upon revision.  These should then be listed as distinct
species in whatever genus group they belong rather than under the original
