Parnara species.
antennae short & the clubs thick.
UpF subapical spots 6 & 7in line; if spot 8 is present, it is usually also in line.
UnH may have a diffuse cellend spot.
UnH spot 7 is always absent.
This practically certain to be a female Arhopala milleri.
Note the longer palpi (labial palps) The abdominal end with a longer slant cut.
Compare with a male A. sublustris given below.
Three species recorded in Singapore are very similar & almost impossible to identify correctly.
A. sublustris is the most common
UnF postdiscal band uppermost spot 9 is typically dislocated & shifted inwards on the costal margin.
UnH spot 6 widest at the top & tapers down wards.
Male upperside bright blue, more reflective. Female with HW brown border wide. FW blue not reaching the tornal margin, brown border being uniformly broad https://yutaka.it-n.jp/lyc4f/82170010.html
This is likely A. sublustris male. https://www.inaturalist.org/observations/189202433
See Otsuka L206.
A. milleri. UnF postdiscal band spot 9 less dislocated ,sometime in line with the rest.
HW spot 6 as in A. sulustris
Male darkisk less reflective blue. Female UpF blue reaches tornal margin ,HW brownish blue reaches the margin. https://yutaka.it-n.jp/lyc4f/82160001.html
see Otsuka L207 for female.
A. normani . UnF spot 9 slightly dislocated.
UnH spot 6 with the side margins straighter.
Male upperside darker blue than A. sublustris.
