Neurotoma silla sp. nov. is described and illustrated from South Korea. It belongs to the N. saltuum subgroup of the N. nemoralis group and is well characterized by the large size, the mostly black body with mostly black antennae and partly pale yellow legs, the densely punctate but nearly glabrous head with smooth interspaces between punctures, and the sharply carinate occipital carina. Six species of Neurotoma are known now from South Korea, including three species endemic to the country. A key to the South Korean species of Neurotoma is given.
