This is quite tricky, but I think you have the female of Parnara ganga.
The apiculus looks very small & abrupt joining the club, but there is a small possibility of distortion due to the angle of the shot.
Comparing with the female of P. mathias here(Federick's) & that in the Checklist, the shape of the hindwing is different, ie the upper margin (costa) of the hindwing is shorter than that of P. mathias, which is as should be for Parnara ganga.(P. apostata is rather dark.)
If you have a slightly top view the taper of the apiculi, abrupt or gradual with be noticeable, ie compare with the upperside shot of P. mathias in the Checklist. If so, this should remove all doubts.
