Abstract: Pagurus is the most diverse hermit crab genus in Korea. In this study, the cytochrome c oxidase subunit I (COI) and 16S rRNA of 24 individuals from four Korean Pagurus species (i.e., 7 Pagurus brachiomastus, 8 P. proximus, 8 P. simulans, and 1 P. rectidactylus) were sequenced and analyzed. No genetic difference was found between the COI and 16S rRNA sequences of P. brachiomastus and P. simulans, and the COI sequences of P. rectidactylus and P. quinquelineatus (comparative species from NCBI). Considering the morphological and ecological characteristics together, we assume that P. simulans and P. rectidactylus are subspecies of P. brachiomastus and P. quinquelineatus, respectively. This study should facilitate further research on the taxonomic status of these species.
