1. Arhopala epimuta.
FW with spot 4 dislocated & displaced outwards; HW postdiscal spot 6 astride spot 5 & the cellend bar; HW tornus with a white cilial dot.
2. is rather tricky ; Dark striae within bands obsolete.
HW postdiscal band in space 4 well separated from the submarginal spot ; in space 5 they are close.
FW postdiscal band straight & without dislocation.
The appearance is very similar to a female N. sanaya but all sanaya have the FW postdiscal band broken at vein 6.
Male & 3 female N. sanaya showing the FW band dislocated at vein 6.

That leaves only two possibilities .N. pendleburyi & N. solta.
N. pendleburyi recorded in Singapore but I can't locate the correct image anymore.
This BOLD image is actually that of N. pactolus.

In any case the FW band in N. pendleburyi is curved whereas this is very straight.
This suggest it may be N. solta which would be a new record.
N. solta male ? Borneo.

TL Seow: Cheers.
There are a lot of variations in each species & the key features are not precise.
Looking thru the Bornean Nacadubas N. solta is out of the picture as the HW submarginal spots & the postdiscal band/spots are widely separated.
It resembles N. hermus closely.
TL Seow: Cheers.
Could it be an aberration for a N.sanaya as we found another N.sanaya nearby.

Post 4.
None of the features are absolute so it could still be a female N. sanaya.
Your post 4 image raised more question as the HW postdiscal band & the submarginal spots in space 4 & 5 are so close it suggest N. subperusia lysa, a species recorded from Singapore.
N. pendleburyi is unlikely as the submarginal spots are narrow so that postdiscal & submarginal spots are widely separated.
Of the three N. sanaya, hermus ,& subperusia all recorded in the past, the defining feature is.
N. sanaya :postdiscal band/pots & submarginal spots separated by at least 1/2 the width of the postdiscal band in space 4 & 5.
N. hermus & subperusia lysa ;HW postdiscal & submarginal spots very close ,almost touching.
As can be seen in sanaya & hermus this key feature is variable, possibly so too in subperusia.
N. hermus nearly always have metallic scales on the black tornal spot.

This unIDed Singapore image is obviously male N. hermus.

Nacaduba subperusia lysa. Similar to N. hermus but lack metallic scales in black tornal spot.

Best to leave it as ?N. sanaya until there are definitive examples.
