    E. acroleuca apicalis

    Previously the continental population was given as E. acroleuca apex.
    Taxon apex type location Luzon is now considered as a ssp or full species & is not aplicable to the mainland population (unless the Philippine & continental forms are considered the same.)

    There does not seem to be any article treating taxon apex as a separate species.
    See PDF ,A taxonomic note on Erionota acroleuca.

    Unusual form E. torus males with large white are on the club. HW patch partially narrower .Probably of hybrid origin with E. acroleuca.
