The Tribe Prosternini of the subfamily Dendrometrinae comprises approximately 530 species in 39 genera through the world. Especially about 250 species in 20 genera with 13 subgenera has been known in the Palaearctic region. In process of the taxonomic study on the members belonging to this tribe in Korea, the authors recognized a new genus including to three new species. This new genus has close affinities with species of the genera Acteniceromorphus Kishii 1955, Liotricus Kiesenwetter 1858, and Actenicerus Kiesenwetter 1858. The novel genus differs from mostly allied to the genus Acteniceromorphus in its specialized paramere shape in the male genitalia, lacking unicarina on the pronotal hind angles, and the character state of the prosternal process. This presentation is given that above four genera including the new genus from Korea are compared to discuss their place in classification by basis of morphological information.
