Jimmy in Argentina live about 200-400 species and subspecies of Camponotus , it is really hard to know from pictures which specie are these queens

... it is able only if you have some taxonomically documents and special tools in home
I can tell , it is not ligniperda , blandus and maculatus also
First one you must research which subgenus is it:
it Camponotus 100 percent
but which one?
Colobopsis ? Tanaemyrmex ? ... ot which?
if you´ll look on diffenrents btw these types ( tanaemyrmex...etc) , then you can know more
Of course that bigger one looks like darker substitutus campo sp.
