Revision No. 2.

There seem to be a tooth at vein 2, a 'V' mark can just be made out at vein 2, just that it is out of focus.
The medium size would exclude both zylda & stubbsi.

With the presence of the tooth it is either A. amphimuta or major.
The postdiscal band is fairly intact & the V spot though fat have equal arms.

Most likely A. amphimuta
My slight reservation is that in this male the bit of HW upperside margin does not show any blue.
Typical A. amphimuta.
