Caucasian troops for the Heraklian Byzantines

[AntiokosIII]

 The Heraklian list (312) mentions troops from the Caucuses, but these are bot described in the troop description. Is it that they are all included among the 'hillmen'? If some were cavalry, how should they be represented? I thought there were some Armenian cavalry along, but  I am still looking for references on this and would not be surprised to learn I am wrong.If I decide to represent these non-allied co-belligerents, which line in the list do
'I use?
Thanks

The "Lazoi, Abasgoi, Tzanoi and similar javelinmen" are the troops from the Caucuses. Other than their presence there is no real detail about them.
