Apristus Chaudoir is one of the genera in the tribe Lebiini Bonelli (Coleoptera: Carabidae). This genus is morphologically similar to Anomotarus and Syntomus of Lebiini. However, Apristus can be distinguished from the other genera by having a combination of the following characteristics: basal pronotum with distinct posterior angles in dorsal view; tarsal claws smooth without denticulate or pectinate. A total of 61 species of Apristus are distributed worldwide and only one species, Apristus striatus Motschulsky has been known in the Korean peninsula. As results of taxonomic studies on Korean Apristus species, we discovered a newly recorded species, Apristus cuprascens Bates of Apristus. A key to the Korean Apristus species, photographs of diagnostic characteristics and illustrations of male genitalia are provided.
