The longhorn beetle (Coleoptera: Cucujiformia: Chrysomeloidea: Cerambycidae) is one of the major family of coleoptera which contains more than 30,000 species worldwide. Because of their species-diversity, morphological attraction and ecological status, the family has received a massive global attention. However, in Korea, no thorough study on this family has been conducted within last twenty eight years. Here we update the latest knowledge of Korean longhorn beetle fauna. First, we give an historical overview of the longhorn beetle studies in Korea and correct some common species misidentifications. Then we provide the information of updated cerambycidae fauna with 4 new species and 9 species newly reported to Korea. Lastly, we discuss the importance of studying immature stage of cerambycidae and provide brief morphological, ecological information of two recently described species.
