Notes
The butterfly is rare in montane forest at low elevations.
The taxon was described as subspecies of eriphylae, After that Miyazaki et al.,2010 regarded it as distinct species. However I consider it should be subspecies of merta due to morphology. Male is not different from merta in both markings and genitalia. Female looks a little different, but its basic features are the same as those of merta. In Monastyrskii,2019, males of alboapicala and Euthalia eriphylae are misidentified including their genitalia.
A single male was found on 28.iii.1983 in Chanthaburi province, S.E.Thailand. It is likely to be ssp.alboapicala, or it could be a peninsular taxon. It is not certain currently. I am pending the belonging of subspecies until a female is found.
