performed a diversity study on parasitic barnacles (Crustacea:
Cirripedia: Rhizocephala: Peltogastridae) that parasitize hermit crabs
in Korea. Their morphological, ecological, molecular (cytochrome c
oxidase subunit I, 16S rRNA), and biogeographical characteristics were
examined. Three species were identified based on GenBank sequences and
the external morphology of the externa. In addition, this study
proposes four new candidate species. This is the first report on the
family Peltogastridae from Korea. Six hermit crab species were found to
be new hosts to peltogastrids. Korean peltogastrids are less prevalent
on their host hermit crabs than those from Japan are, especially in the
west coast of Korea. Peltogasterella gracilis is widely distributed throughout Korea, Peltogaster lineata is located on the east coast, and Peltogaster postica is only located on Jeju Island.
Key words: Parasitic barnacle, Paguroidea, Morphology, DNA barcode, Ecology, Biogeography.
