Euthalia adonia or Euthalia lubentina

[DaveChiangMai]

This individual was photographed at 640 metres in Yala, southern Thailand, 22 Jun 23.
I am pretty sure I can narrow it down to either Euthalia adonia beata or Euthalia lubentina chersonesia, but I have no experience with either of these two forms.
In the limited literature they look incredibly similar. Please could I have some expert opinion of these two and how to separate them.
Many thanks.
