I have assumed 2 to be a member of the alea subgroup but just cannot get the combination of features to match.

After scrutinizing all the undersides, I think I have made an important discovery.
If the postdiscal spot in space 4 is dislocated and out of alignment with the spot in space 5 above and the spot in space 3 below, it is always a member of the alitaeus group.(Holds true for all undersides seen.)
This means the spot in space 11 can be obsolete in some examples of the alitaeus group.
Following this line, 2 should be A. elopura.

Antonio's pic is typical alitaeus member & should be A. ariana.
