The genera Spilonota Stephens, 1834 and Lepteucosma Diakonoff, 1971 are belonging to the tribe Eucosmini, subfamily Olethreutinae. In Korea, there are five species of Spilonota recorded: S. albicana (Motschulsky, 1866), S. eremitana Moriuti, 1972, S. lechriaspis Meyrick, 1932, S. ocellana ([Denis & Schiffermüller], 1775), and S. semirufana (Christoph, 1882). Only one species of Lepteucosma is recorded: L. huebneriana (Kocak, 1980). Both genera are agricultural pests that infest host plants belonging to the family Rosaceae, specifically causing damage to genus Malus (apple trees) and genus Rubus (blackberry plants), respectively. In this study, we provide a checklist of Korean Spilonota and Lepteucosma, with information of host plants and distribution for each examined species.
