Oops!
I was too preocupied with 6line blues.Once I opened the answer box, I can not see the image again until I finished the reply.

This is Nacaduba hermus.
Resembles N. sanaya but the FW postdiscal band is generally unbroken, & there is always some metallic blue scales in the HW tornal black spot.

N pactolus looks similar but HW submarginal spot 6 is very angular , while the rest of the submarginal spots form a narrow regular band, a very distinguishable feature. White striae are also enhanced.
