Leafhopper subfamily, Typhlocybinae (Hemiptera: Auchenorrhyncha: Cicadellidae), caused direct damage by sap-sucking or indirect damage by transmission of viruses or diseases on the host plants, so typhlocybinae is one of the important pest groups in the world. Typhlocybinae distribute worldwide and a total of 471 genera and more than 4,300 species have been described. so far, 38 genera and 102 species were recorded in the Korean Peninsula. In this talk, we provide several taxonomic studies for the Korean typhlocybene fauna based on the genus-level reviews of the subfamily from the Korean Peninsula.
