It is most likely Nacaduba hermus swatipa.
There are quite anumber of 4line bliues recorded in Singapore which can be very difficult to ID.
N. pavana ( & russelli) both have strongly developed dark striae within the bands. HW black spot with metallic scales.

N. pendleburyi. No pix.
Dark striae absent.
Submarginal spots narrow , so they & the postdiscal band are widely spaced.
Male upperside FW with narrow black border expanding at apex.
If you look carefully at the HW black spot, there are a few metallic scales.
TL Seow: Cheers.
Thanks for the detailed explanation!
