    The tachyporine genus Bolitobius Leach contains 20 species in the Palaearctic region including two species in Russia (Far East), three species in China (North-East), and four species in Japan. In Korea, Bolitobius parasetiger Schülke and Bolitobius setiger (Sharp) have been recorded (Ahn et al., 2017). They are found from fungi.

    Members of Bolitobius are characterized by the combination of the following features: head small; labial palpus with 3 palpomeres, apical palpomere very large; elytra longer than pronotum with five discal rows. As a result of a taxonomic study of Korean Bolitobius, we discovered Bolitobius princeps (Sharp) for the first time in Korea. Photographs of adult habitus and diagnostic characters with line drawing are provided.

    Materials and Methods

    The specimens used in this study are deposited in the Chungnam National University Insect Collection (CNUIC), Daejeon, Korea.

    Remarks. This species can be easily distinguished from the other Korean species by brown elytra and male sternite VIII with a pair of patches of setae.
