    Default Which Erionota?

    Is this a female E.hiraca or E.torus? The FW is a bit deformed.

    Female Erionota acroleuca apicalis.

    More recent research have shown the taxon (taxonoic name) acroleuca have priority over taxon hiraca which was named from an Andaman specimen.

    This specimen is also abnormal in having wholly black club.

    Erionota acroleuca.
    FW termen (outer margin) straight, with an angulation at vein 5 near the apex.
    HW patch narrow with a strong step ( space 6) in the upper half.
    Ground dark shaded & heavily speckled & mottled with paler grey/brown.
    Females.

    Female have little whitening of the FW tip.

    Form with the HW patch similar to E. acroleuca, but step wider angle. Note it does not have the speckled mottled look.
