Dear Zach,

There is obviously a difference in entomological thinking as while
LepSoc (no formal list) & NABA (currently uses Battus & Parides as below
and Papilio for the remainder--tho understand the list is under
consideration for updates & revisions this year), the recent Mexican
Pap/Pierid book shows several different genera and broken down below as
I see them.  There may very well be other criteria that also applies. 

Pterourus for the Tiger Swallowtails & esperanza
Protographium for tiger-striped Kite-Swallowtails, 
Protesilaus for seemingly (?) the larger tiger Kites, 
Eurytides for salvini, a white non-tiger Kite-Swallowtail 
Mimoides for the single row red-spotted swallowtails,
Priamides for the double row red-spotted swallowtails, 
Troilides for torquatus - banded w/apex bar
Calaides ornythion, astyalus & androgeus - wider-banded w/dimorphic
Heraclides for thoas & cresphontes - large sized, narrow-banded
Pyrrhosticta for abderus, garamas & victorine - the mostly black

continuing with: 

Battus for polydamas, philenor, eracon, lycidas, - black w/blue or
Parides for the red-spotted Cattlehearts - forewing shape seems more
rounded than 	Mimoides & Priamides - other differences anyone?
Papilio for indra, zelicaon, machaon and polyxenes - largely black at
base, at least 	some dimorphism

My thoughts are that it seems to be more realistic to have the differing
groups split into separate genera as we certainly don't have all the
sulfurs, blues, etc. in just one genera.   

Does anyone happen to know why esperanza* a wide-banded bug was placed
into Pterourus rather than Calaides?    Certainly not tiger-striped and
is dimorphic.
