,
13-15mm. The shape of the patches in the wings is as in cyclaria but
these are darker, browner as in malaysiana and argentilauta. The
male genitalia resemble those of the other three species, distinguishing
features being in the aedeagus vesica. Cornuti are large as in cyclaria but
there is a small bulbous lateral lobe that is also lined with cornuti along one
side. The female has a diagnostic triangular sheath-like evagination on the
bursa that may receive this lobe on the aedeagus. The bursa is sclerotised over
the basal half, with a few small, irregular fields of spines within this
sclerotised zone.
