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.

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.

As a caution that no single feature is absolute.


Typical C. aristogiton.

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