Lophoptera univalva sp. n.

Lophoptera univalva

13-15mm. The forewings are relatively deep for the genus, a uniform dark brown with fasciation obscure except for a distinctive, oblique, straight, pale brown postmedial and an irregular submarginal row of pale brown dots. The male genitalia have a simple, elongate valve that tapers to an acute apex and is unadorned except for a slight longitudinal ridge; the uncus is laterally flattened, expanded ventrally over the basal two thirds. The membrane between abdominal segments 7 and 8 has a corema on each side, broader than in the doubled coremata of the previous two species. In the female genitalia the post-ostial invagination is moderate, slender, closely flanked by the small setose lobes.
