The difficulty in your area are the wsf & dsf , forms which greatly alter the appearance of the species.


Polura athamas (I leave this as P. athamas though in India it is now Charaxes bharata.
1. Upperside band pale yellow- green & underside often strongly yellow-tinged.
2. FW strongly excavated with apex produced & sharper & distla margin more angulate at vein 2.
3. FW cell with two cellspots ,sometimes one.
4. A line drawn along the outer border of the FW band will cut most of the subapical spot.
5. Subapical spot usually quadrate.
