The first discovery from Thailand is the specimen from Nan shown above. The butterfly is uncommon in montane forests at moderate elevations (Alt. 1100 - 1300m). Males frequently come to the banks of streams and puddles to suck water. This species is found sympatric with Pseudocoladenia fabia.
The populations from Laos and Vietnam are tentatively included in this taxon, but require examination of male genitalia. Further taxonomic and distributional studies, including DNA analysis, are needed.
