It looks like you have the rare A. milleri.
The upperside is described in C&P4 as a 'more matt darker indigo blue'. It is not totally non-reflective.
I have seen a number of A. sublustrus uppersides & this is definitely not it.
Most A. milleri have FW spot 9 in line with the band while in A sublusris it is more often shifted in.
Another member recorded in Singapore is A. phanda
The upperside is dark reflective blue & on the underside spot 6 & 7 are like a column.
This one below from Langkawi should be A. evansi.
