The beetle family Chelonariidae contains 11 described species in the Palaearctic region, belonging to two genera (Chelonarium and Psedochelonarium). However, no members of this family have been found in South Korea. We collected a single female specimen of Pseudochelonarium japonicum (Nakane) near a mountain stream in northern South Korea. Illustrations of the habitus with related Japanese species, diagnostic characteristics, and mitochondrial DNA sequence for Pseudochelonarium japonicum are provided.
