Male Nacaduba berenice. Correction : Nacaduba hermus.
The two smaller 6-line blues, N berenice & calauria can sometimes be difficult to ID.
There are probably hybrids causing intermediates.
N. caluria; FW postdiscal band almost always straight, & unbroken.
There should not be any dislocation ie. breaks in the white striae forming the margins of the band.
FW only submarginal spots 4 & 5 pointed, somewhat triangular or haert-shaped.
All valid examples.
Pairs male on the right.

Variable. Typically some dislocation of FW postdiscal band ,usually mid at vein 4 or at vein 3 or 5.Also often rather crooked.

Dear Dr Seow,
There's only four line, probably should be Nacaduba pactolus odon instead of berenice? Thanks.

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.
