DNA Barcoding of Eurydice longiantennata (Isopoda, Cymothooidea, Cirolanidae) from South Korea

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.
