Odd Polyommatinae(?) from s Thailand. Ideas please?

Although this individual looks rather worn, the positioning of the lines looks so haphazard that I am not even sure what subfamily this is.
Photographed at Bang Lang NP on the Malaysian border.
It might be something common, and totally worn. I'd welcome opinions and ideas.
My first thought, based on the number of bars on the forewing would be Nacaduba sp.
But the scattering on lines elsewhere do not match.
Arhopala even crossed my mind.
I am stuck for ideas even.
Many thanks.

Many thanks for that. Yes, extremely worn I see. Mystery solved.
