Notes
The butterfly is locally not rare in montane forest at lowland (alt.150 - 350m).
Yokochi,1999 recorded from S.Thailand however I have never seen any materials from P.Thailand. Considering it is distributed in Langkawi, the taxon is highly likely to be distributed in peninsular region. The populations in Sa Kaeo province, E.Thailand are variable and some examples are close to ssp.osadai. Further taxonomic study and distribution research are needed.
