An Arhopala from Keang Krachan

[DaveChiangMai]

I am posting this for a friend, so not my photo. Photographed this week at Kaeng Krachan. Thought by the photographer to be Arhopala pseudomuta. However, this would be out of known range and is already very rare in Thailand. So I think the tentative ID is incorrect. Problem is I cannot suggest a better identification. Any help on this appreciate.
With thanks.

Arhopala aida .

The FW spot 4 dislocation & the HW complete dislocation of the postdiscal band at vein 2 marks as a member of the alitaeus group.

A. pseudomuta (& alitaeus) have a spot at the base of space 10 which appear as a spot on top of the middle cell band.
