1. Female Nacaduba sanaya.

2. Male Arhopala major.

The two spp. A. major & amphimuta are nearly identical on the underside .

A. amphimuta ;HW V spot with equal arms. The spots above the V spot more in line; upperside wholly blue.

Your pic also shows a bit of the upperside near the black spot. In A. amphimuta this bit of upperside is blue .
