Euthalia eriphylae ssp.
Distribution : N.Vietnam.
[ VIETNAM ]
Euthalia eriphylae lioneli ; Monastyrskii,2019 : 4(2):117-118, pl.64, figs.1d♀. (N: Ba Be) (in part)
The classification of the three species, including eriphylae, mahadeva and merta, has been confusing from the past to the present.
The reason is the markings of each species are very similar, there is no difference in the male genitalia and they are all uncommon, making it difficult to collect specimens for comparison.
I suspect that taxa with small, underdeveloped white spots on the UpF are Euthalia eriphylae, and that taxa with large white spots (for instance chula and lioneli) are Euthalia mahadeva. The populations that I consider to be eriphylae occur very locally in the Malay Peninsula (ssp.elioti), Langkawi-Tarutao Islands (ssp.raja), W.Thailand to C.Myanmar (ssp.eriphylae), and N.Vietnam (undescribed ssp.). The species is rare or extremely rare in all regions and occurs sympatrically with Euthalia mahadeva. The distribution map of eriphylae excludes some taxa such as chula and lioneli etc., which could be Euthalia mahadeva. As for the eriphylae-mahadeva complex, further field research and DNA analysis are needed.
