Abstract: The pulmonate gastropod Ellobium chinense (Pfeiffer, 1864) is an endangered marine species along the South Korean coasts due to habitat destruction and population declines. We sequenced the cytochrome c oxidase subunit 1 (COI) of 25 E. chinense specimens collected from five coastal sites in South Korea, and identified 16 unique haplotypes. The maximum intraspecific variation among individuals was 1.6%, while interspecific differences from another ellobiid species, Auriculastra duplicata (Pfeiffer, 1854), ranged from 21.9 to 23.0%. Our barcoding data will be useful to elucidate the phylogenetic relationships among pulmonate gastropods and infer the population genetic structure of E. chinense.
