New record of Eumonopyta Moriuti, 1977 (Lepidoptera, Yponomeutidae) from Korea

An yponomeutid genus Eumonopyta Moriuti, 1977 is recorded for the first time from Korea, based on the species Eumonopyta unicornis Moriuti, 1977. Eumonopyta is distinguished from Yponomeuta by the lack of the areole in the forewing, the presence of the hindwing veins, Sc and R₁ completely fused, the lack of the spinules on the gnathal processes, and the presence of three spiniform cornuti in the phallus. Eumonopyta unicornis is characterized by the presence of greenish irrotation on the forewings. The Korean records of E. unicornis are based on two male specimens from the islands, Geojedo (Gyeongsangnam-do) and Jejudo (Jeju-do) and one female specimen from the island Dolsando (Jeollanam-do). External appearance and genitalia of E. unicornis are redescribed and illustrated. The occurrence status of E. unicornis in Korea is briefly discussed. With our records from Korea, the distributional range of E. unicornis is expanded from Japan and Taiwan.
