Notes

New to Thailand. The first discovery was photographed by Supat Sophonviwatkul on 15.Apr.2012 in Soi Dao district, Chanthaburi.
Only a few examples from S.E.Thailand were known until now. I treat it as this taxon temporarily, however further taxonomic study is needed with more specimens.
I have once seen a male in Chaiyaphum province, C.Thailand, but it was only a sighting. Therefore, I am not sure if that was this taxon or another one. Confirmation by specimens is needed.
The butterfly is locally not rare in montane forests at low to moderate elevations (Alt. 350 - 1000m), and frequently rests on the underside of leaves.
