New to Thailand.
I recorded it from Chiang Mai and Lampang, N.Thailand as Pseudocoladenia festa on my website, however these were misidentification of Pseudocoladenia fatua as Huang,2021 pointed out. The butterfly is locally not rare in montane forest at moderate elevations (alt.1100m - 1300m) and is found around small streams. This species is found sympatric with Pseudocoladenia dan fabia and Pseudocoladenia dan dhyana in its habitat.
