Two live specimens of the mud snail, Nassarius sinarum, was collected from the Yeongsan River estuary in Jeollanam-do, Korea, during June 2022. The species was identified based on its morphology and DNA barcoding.

Morphological descriptions and photographs of N. sinarum were used to verify its occurrence in Korean waters as an invasive species. The species is characteristic in its axial ribs, which weaken towards the outer lip. Molecular analysis of the mitochondrial DNA cytochrome oxidase subunit I gene showed that the specimen belonged to N. sinarum with 98.48–99.69% sequence similarity. The new Korean name of “No-lan-jul-job-ssal-mu-nui-go-dung; 노란줄좁쌀무늬고둥” was proposed for the species.
