Yes, it is A. silhetensis ardorea. Correction: Arhopala athada.

Some examples of A. silhetensis have HW spot 6 broader, astride spot 5 & cellend bar & is very similar to A. athada.
See the last female from Ranong.

However A. silhetensis also have the FW top submarginal spot more strongly dislocated with a distinct step on the outer border.

Correction.

Much more likely to be Arhopala athada athada.
There is probably some hybrid element here.

However A. silhetensis is a very large species & the bands are far apart.

A. silhetensis.
On the FW the postdiscal & submarginal bands are 2- 2.5 X the width of the postdiscal band apart.

A. athada is usually a smaller species & the postdiscal band tend to be wider.
FW postdiscal & submarginal bands about 1- 1.5 X the width of the postdiscal band apart.
