I have had a possible 'dwarf' Arhopala tentatively suggested to be this species before. This one is 39mm. in wingspan, and, I think is A. athada. The only problem is that the upperside black border is 1.5mm. in width reaching 2mm. at the apex, which, I think is a bit too broad for the species.
If it is, I would think the 'dwarf' is the same, as I found this at the same site.
