Photographed at Chiang Dao, n. Thailand yesterday.

This should be either Y. akbar or Y. watsoni. But which?

Usually on images of akbar the hindwing ocelli are absent and there are two fairly prominent discal and post discal bands, lacking on this individual.

The fairly even size of the apical spot and spot 2 could refer to either, but rules out Y. confusa.

Thoughts appreciated. My leaning is toward Y. akbar, though the prominent ocelli I have not seen before.
