New to Thailand.
The earliest record from Thailand, to my knowledge was obtained by T.Aoki & S.Yamaguchi on 28.Jan.1979 in Chiang Mai Province, N.Thailand. The butterfly is locally not rare in montane forest at low to moderate elevations (Alt. 350 - 700m).
The continental population has long been confused with Euthalia mahadeva binghamii and Euthalia eriphylae eriphylae. The corresponding name is pseuderiphyle, but this is an infrasubspecific name and cannot be used. A new name needs to be assigned.
