Dura alba Moore sensu Schintlmeister,
This is a smaller species than amianta, but otherwise very similar in
fades. The forewings are perhaps relatively broader, with a slightly darker
brown spot at the end of the posterior arm of the discal chevron. The margins of
both wings are slightly more darkly punctate in the spaces. These features tend
to disappear in worn specimens, but the male genitalia are distinctive. They
resemble those of alba Moore (= ippoline Schintlmeister as
determined from the genitalia illustration and description, syn. n.), but
have a much longer uncus and shorter, more equal valve processes. The eighth sternite is weakly
bilobed rather than biangular.
