Notes

New to Thailand. The first finding is taken photo by Mr.Supat Sophonviwatkul on 15.Apr.2012 in Soi Dao district, Chanthaburi.
It has been known only a few examples from S.E.Thailand until now. I treat it as this taxon temporarily, however further taxonomic study is needed with more specimens.
I have ever seen a male in Chaiyaphum province, C.E.Thailand, but it was only a sighting. Therefore, I am not sure if that is this taxon or another one. Confirmation by specimens is needed.
The butterfly is locally not rare in montane primary forest at low to moderate elevations (alt. 350m - 1000m).
