Scopula phallarcuata sp. n.

Scopula phallarcuata (holotype)
(x 1.16)

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).
