Members of the syrphid subtribe Xylotina generally resemble sawflies in their appearance and behavior. In Korea, seven species of this subtribe have been recognized so far (three Xylota spp., one Brachypalpus sp., and three Chalcosyrphus spp.). In the process of reviewing the species of Xylotina in Korea, we found new species records for the country. The largest genus of this subtribe, Xylota, is not discussed here but will be detailed in a future publication. We found that previous Korean records of B. laphriformis were actually misidentifications of B. nipponicus. For the genus Chalcosyrphus, we recognized the following nine species including six species new to Korean syrphid fauna (asterisks for new records): C. carbonus*, C. femoratus, C. laterimaculatus (new name), C. longus, C. nemorum*, C. nitidus*, C. piger*, C. rufipes*, and C. unicus*. Among these species, we still have not found any specimens of C. longus, which was recorded in North Korea by Doi (1938). In addition, we rename C. frontalis (Shiraki and Edashige) to C. laterimaculatus due to homonymy. We also provide an identification key, diagnoses, and descriptions with color photographs of the inclusive species.
