It is not Y. fasciata.
Ypthima fasciata is strongly marked with 2 straight fasciae & the ocelli more nearly in line.

The submarginal ocelli are well out of line & the upperside is different.
From the upperside it is one of these three, Y. baldus. singorensis, or nebulosa.
Perhaps Y. singorensis from the UnH straighter fasciae.
You may download this article on Vietnamese Ypthima & check out page 33, fig 4 , 7 , & 10.
