Arhopala sublustris.
The markings are as for the alea subgroup.
The shape of HW postdiscal spots 6 and 7 suggest A. sublustris and close relatives.
There is a bit of tear of the FW showing just a hint of light blue, the colour seen in sublustris.
Practically all others in the group are rather dark blue or deep violet.
