Genus Tautoneura Anufriev, 1969 (Hemiptera: Auchenorrhyncha: Cicadellidae: Typlocybinae) were recorded 59 species in the world. Among them, only 1 species: Tautoneura mori has been recorded so far in the Korean Peninsula. Tautoneura mori is known as a major pest of Mulberry in China and Japan, and we also confirmed that it appears on Mulberry in Korea. In this talk, we confirmed two new records: Tautoneura japonica, Tautoneura tricolor to the Korean typhlocybinae fauna, and we also discovered one new species to science. Additionally, we provide biological information such as host plants and distributional records, with a key to the Korean Tautoneura species. We also discuss potential status of each species as an agricultural pest concerning its biological traits.
