Arhopala atosia & lurida can be quite difficult to separate.
A. lurida is darker with better contrasted markings.

Perhaps this feaure is correct after all.
In A. lurida the hindwing postdiscal spots 4 & 5 (just to the outside of the cellend bar) have a wide overlap.

In A. atosia postdiscal spot 4 & 5 are staggered & have little overlap.

This holds true in C&P4 plate 65/ 14 & 15.
It also holds true in Fleming's images of these 2 species.

Les, you did ask about this a long while back but at that time I thought it was a variable feature.

Thus this should be Arhopala lurida.

PS. An example of the local race A. atosia malayana showing postdiscal spots 4 & 5 staggered with no overlap.
