The V spot doesn't look very strongly angled to me actually... I think the upper 'arm' is slightly shorter.
The other features are the size of discal spot in space 7 in relation to the space 6 and 7 postdiscal spots, and the dislocation of the postdiscal spots at vein 4. (correct me if I'm wrong!)
From what I see, the discal spot 6 is very slightly smaller than the postdiscal spots 6 and 7, almost equal size. The postdiscal band also appears very slightly disconnected at vein 4. I would suggest it is A. major in that case, but all the features are barely there.
This fit the perfect Arhopala amphimuta.
1. The 'V' spot have equal length arms.
2. The postdiscal spots 2, 3, 4, & 5 above it are fairly well- aligned. (Not broken/dislocated strongly in the middle at vein 3.)
3. Postdiscal spot 7 & discal spot 7 are equally large. http://4.bp.blogspot.com/-J9Xmngyim6...+amphimuta.jpg
