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

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.

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.
