New to Thailand and Myanmar.
The butterfly is rare in montane forests at moderate elevations and only one speimen has been known in Thailand.
I recorded it from Chiang Mai, N.Thailand and Kachin, N.Myanmar as Coladenia uemurai on my website, but it was a misidentification of Coladenia tanya, as Huang,2021 pointed out. This species can only be distinguished from Coladenia agni by the examination of the male genitalia.
