TL Seow: Cheers.
Thank you for your feedback. Yes, we all know about the tricky genus of Charaxes. After getting your reply I further studied about it. I am sharing with you.
UNF inner edge of the discal band is not so closer to the cellend bar like as Charaxes bernardus hierax.
HW with a series of narrow post discal white spots in spaces 1b-5 is small and outer edged not by broader black spots.

Thanks and Regards,

Agreed .
The closeness of the discal band to the FW cellend bar is fairly consistent in C. bernardus .
I actually did look at it before but it can be difficult in some examples.
This means your specimen is Charaxes aristogiton.
You could try a scrutiny of the difference between C. bernardus & C. psaphon.
TL Seow; Cheers.
Thanks a lot Sir.I will try to scrutiny as per your guidance.

As a caution that no single feature is absolute.
Typical C. aristogiton.

C. aristogiton with the FW discal band near to the cellend mark.

C. bernardus crepax with the discal band not near the cellend. Langkawi, P. Malaysia ,where C. aristogiton is absent.
