Three Species of Adelidae (Lepidoptera) New to Korea

The family Adelidae, commonly known as 'Fairy Long-horn moths' is a group of primitive monotrysian moths belonging to superfamily Incurvaroidea. Based on the material in the collections of the Kangwon Nat. University, Incheon University, and Korea National Arboretum, Korea, we found that three species Nematopogon dorsigurella (Erschoff, 1877), Nemophora decisella (Walker, 1863), and Nemophora smaragdaspis (Meyrick, 1924) are known for the first time from Korea. Taxonomic notes and photographs of adults and male and/or female genitalia for newly known species are illustrated.
