Notes

The butterfly is uncommon in montane forests at low elevations.
A female specimen from Phetchaburi appears to belong to ssp.ariadeva rather than ssp.burmana; therefore, I provisionally treat it as this taxon. The subspecies identity of the population from Koh Samui cannot be determined due to a lack of specimens, necessitating confirmation through further material.
