Need ID keys for Euthalia

[ButterflyWitch]

Good evening Dr. Seow Sir...

How can I differentiate these similiar looking species - Euthalia malaccana, Euthalia lubentina?

Is it Euthalia lubentina?

Yes. This is male Euthalia lubentina.

The two species differs very little and can be difficult to ID in fieldshots.
