Four individuals all from Chiang Dao, n Thailand.

On the basis of the cell end bar touching spot 5, I make image 1 and image 2 to be A. agaba.
However I do not like the fact that the FW apex is not whitened.

Image 3 and 4 should be A. aurleia (I hope).

Image 3. A. aurelia.

Image 4. A. aurelia.

Last one is probably Arhopala zambra. It lacks the purple glaze in the other two

4 is unknown member of the alea subgroup.
The rounded FW margin suggest it is A. selta.

You got a point here.
FW spot 10 is large & in line with the cellend bar as in A. zambra.
A. zambra is large & the markings are spaced out & as with all large species the V spot is well-formed & separated.

Still it could be A. zambra.
