Two land snails, Aegista chejuensis (Pilsbry and Hirase, 1908) and Plectotropis quelpartensis (Pilsbry and Hirase, 1908), are endemic to Korea and were collected from Hataedo and Jodo Islands in the Yellow Sea of South Korea, respectively. Many terrestrial snail habitats have been confirmed in Korea; however, their genetic sequences have rarely been reported. This study describes the mitochondrial cytochrome c oxidase subunit I gene (COI) sequences of two species, followed by an analysis of the genetic distance between these two species and their congeners. As a result, there was no intra-species variation in both species A. chejuensis or P. quelpartensis. However, the inter-species variation was clear (10.3-31.5%). We provide photographs and a brief diagnosis for morphological verification.
