The genus Eutetrapha belong to the subfamily Lamiinae of the family Cerambycidae was established in 1884 by Bates, based on a new species, Eutetrapha variicornis Bates, 1884 (= Saperda sedecimpunctata Motschulsky, 1860). Until now, the genus has been known only from Asia, and two species, Eutetrapha metallescens (Motschulsky) and Eutetrapha sedecimpunctata (Motschulsky) are presented in Korea. In this study, we report one species of the genus, Eutetrapha ocelota (Bates), for the first time from Korea with key to the Korean Eutetrapha species, short descriptions, and photographs.
