In a way I am glad you brought this up.
I remembered there was a lot of confusion between what is Y. watsoni, confusa & norma (not found in India)in the past.
This was the cause of several mis-IDs on the web.
The Yutaka website on Ypthima ,updated in 2019 has cleared all these uncertainties.

BTW, you will notice 11D is a near identical match for the female Y. confusa from Chiang Mai.
