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