This study reports the first Korean records of the genus Acerocnema Becker, 1894, with one new species, Acerocnema saurischia sp. nov., and one newly recorded species, A. flavifrons. A key to the Korean Scathophagidae is provided with morphological diagnosis and images of habitus and male genitalia structures. To assist in species identification, mitochondrial cytochrome c oxidase subunit I (COI) gene sequences were obtained from all specimens to conduct DNA barcoding.
