Hi Dr Seow,
I was relooking at the first Arhopala and thinking if it could be A.lurida. It seems to match the features you mentioned on the other thread. FW PD spot 4 dislocated and shifted outwards, HW PD completely dislocated at vein 2, HW spot 7 also shifted inwards, the markings are also contrasting quite heavily. I reattached some other shots of the same butterfly, with a glimpse of the dorsals. I've kept the editing to bare minimum, only touching the exposure slightly. Though I can’t say for certain since the most important part is blocked, but the dorsal borders do seem to be widening towards the apex.

The Oakblues can be very difficult even if you have a specimen in hand.
There are some errors in the past to clear up.
The epimuta group.
Fw with spot 4 distinctly dislocated & shifted out (visible from both margins).
HW with postdiscal spots 5, 6, & 7 staggered in a stepladder fashion.
HW 'V" spot in space 1b narrow & well-formed.
HW tornal green metalmark sharply demarcated with 2-3 black spots.
A. epimuta

A. lurida.

The cleander group.
FW postdiscal spot 4 in line with the rest above it (spots 5, 6, & 9),Less often there may be a slight dislocation outwards of spot 4.
HW postdiscal spots 5, 6, & 7 not arranged in a stepladder fashion, spot 7 being on top of spot 6.
"V" spot in space 1b not well-formed.
HW tornal green metalmark poorly defined with a diffuse inner border.
A. sublustris , alea subgroup.

The wide spacing between the postdiscal & the submarginal spots on the HW is indicative of a large species.
The oblique shape of HW spot 6, wider at the top is indicate of A. silhetenssis.
A. athada always have a blocky spot 6 nearly astride the cellend & spot 5.
#2 https://www.inaturalist.org/observations/177311767
The dull blue upperside already indicate it is A. milleri.
#3https://www.inaturalist.org/observations/175865453
The upperside merely shows a female.
The straighter parallel sides of spot 6 suggest A. normani.

Probably A. sublustris.
FW spot 8 is more dislocated inwards.
Finally this observation which I thought was A. lurida is an alea group member.
Note mwtalmark with diffuse border.
