This is the first record from Thailand. The populations from Nakhon Si Thammarat and southwards seem to be the nominotypical subspecies. In Ranong, both ssp.arata and individuals that very similar to ssp.ace are found sympatrically, but the upper surface colouration is close to that of arata. This area is considered to be a transition zone for both subspecies.
The butterfly is locally not rare in montane forests at low elevations (Alt. 100 - 400m).
