The genus Yponomeuta Latreille belongs to the family Yponomeutidae, with over 75 described species worldwide. This genus is distributed mainly in the Palaearctic Region, comprising 42 species. In Korea, a total of 16 species have been reported from Korea. This genus is reported by Park (1983), with seven species in Illustrated Flora & Fauna of Korea Vol. 27. Bae & Byun (2003) reported four newly recorded species of this genus: Yponomeuta kanaiella, Y. montanatus, Y. sociatus, and Y. yanagawanus. Byun (2009) listed a Korean Micro-Lepidoptera, recording 12 Yponomeuta species, with a newly recorded species Y. solitariellus. Sohn et al. (2010) and Lee & Park (2016) added two species: Y. anatolicus and Y. cinefacta. In the present study, we reported three newly recorded species of Yponomeuta, including adults and genital photographs, host plants, distribution and short descriptions.
