13mm. Though only represented by a singleton, the genitalia are
so distinctive that this small specimen undoubtedly represents a further
species. The underside has dark spots subapically on the forewing as in anomioides,
but the central angle of the margin is more pronounced. On the hindwing there is
a pronounced, somewhat triangular, dark shading at the margin between the tornus
and the central angle. The genitalia have the eighth segment crinkled laterally,
and the ostium is at the anterior of a longitudinal declivity within the
sternite that is bounded posteriorly by a pair of small scobinate lobes. The
ductus is shorter than in other species, of even width, sclerotised and finely
scobinate. The bursa has a neck slightly larger than the ductus and set
asymmetrically on it. The distal part is pyriform and contains two long and
robustly scobinate bands as illustrated, much more pronounced even than in diversalis.
