DNA Barcoding of Six Diogenid Species (Crustacea: Decapoda: Paguroidea) in Korea

Abstract: In this study, cytochrome c oxidase subunit I (COI) sequences of 17 individuals from six Korean diogenid species (i.e., 2 Areopaguristes japonicus, 4 A. nigroapiculus, 3 Paguristes digitalis, 4 P. ortmanni, 3 Diogenes edwardsii, and 1 Ciliopagurus kempfi) were determined and analyzed. The DNA barcoding results of this study were consistent with the morphological identification of these six species. Interspecific variations of COI sequences within six Korean diogenid species exceeded the minimum interspecific variation of diogenid hermit crabs in previous studies. Little intraspecific variation exists except for P. digitalis. This study should facilitate further molecular taxonomy of East Asian diogenids.
