Chaonian Agema and IIllyrioi Thorakitai

[MiniMe]

Could somebody, please, post some evidence on existence of Chaonian Agema and IIllyrioi Thorakitai.

I've just read a very interesting and complete book about Pyrrhos:
1. All his Pezhetairoi phalanx were of macedon origin;
2. Thorakitai were not mentioned at all;
3. Chaonian tribe was in decline already and they weren't supporting Pyrrhos with some significant bodyguard Agemas.

Perhaps I'm wrong about it, but from my point of view, Epeiros wasn't such a unique kingdom different from Diadochi, so perhaps:
1. Greek Thorakitai&Thureophoroi need to be added to their army roster;
2. Chaonian Agema and IIllyrioi Thorakitai&Thureophoroi need to be removed.

Best regards,
MiniMe.
