Scopula phallarcuata sp. n.
7-8mm. This species is like a smaller version of asymmetrica but
with less dentate, more clouded fasciation and a black, rather than grey,
forewing discal spot. The male genitalia are symmetric, as are the long,
incurved cerata of the eighth sternite. The aedeagus is slender, distinctly
curved, distinguishing it from asymmetrica (broad, straight), ophthalmica
and ocellata (shorter, only slightly curved).
