A taxonomic study of the genus Lesteva Latreille in Korea is presented. Four species including a new species, Lesteva coreana sp. nov., are recognized. Three species, L. cordicollis Motschulsky, L. distincta Watanabe and L. miyabi Watanabe, are new to the Korean fauna, and L. plagiata Sharp previously recorded from Korea is a misidentification of L. miyabi. A key and a comparison of morphological features of Korean Lesteva species with illustrations of the diagnostic features are provided.
