Abstract

In Korean waters, the cirolanid isopod, Eurydice longiantennata Nunomura and Ikehara, 1985 has been reported only from the subtidal zone of Jeju island. We obtained the mitochondrial cytochrome c oxidase subunit I (COI) sequences of this species and determined the DNA barcoding data of E. longiantennata based on a genetic comparison of E. longiantennata and its congeners. The intra-specific genetic distance between the three COI sequences of E. longiantennata ranged from 0 to 0.6%. The inter-specific distances between E. longiantennata and other cirolanid isopods ranged from 24 to 33.2%. In this study, we provided the DNA information of E. longiantennata with a morphological diagnosis and images of the species.
