This would be Caltoris bromus female.
Note also in Caltoris bromus & malaya the FW & HW ground colour are about the same.
In C. cahira & cormasa the HW is a deeper darker shade.
Addendum Here the male C. bromus is without HW spot & the female usually but not always have them.
A recent study in Nepal 2022, shows both sexes (?always) have HW spots .
It is thus possible that the occasional male here may have HW spot.
