Morphological and molecular analyses of Korean rhizocephalan barnacle species were performed to examine their host ranges and taxonomy. Morphological examination and molecular analysis of mtDNA , 16S, and nuclear 18S rRNA sequences revealed nine rhizocephalan species from three genera of the two families, Sacculinidae and Polyascidae. Phylogenetic analysis of molecular sequences revealed two new species candidates in the genus , and three species (, , and ) were transferred to the genus Examination of host ranges revealed higher host specificity and lower infestation rates in Korean rhizocephalan species than rhizocephalans from other geographic regions. This is the first report of the taxonomy, species diversity, and host ranges of Korean parasitic rhizocephalan barnacles based on their morphological and molecular analyses. More information from extensive sampling of parasitic barnacles from a wide range of crustacean host species is necessary to fully understand their taxonomy, prevalence on decapod hosts, and phylogenetic relationships among major rhizocephalan taxa.
对韩国根头目藤壶物种进行了形态学和分子分析，以研究它们的宿主范围和分类学。对线粒体DNA、16S和核18S rRNA序列的形态学检查和分子分析揭示了来自囊藤壶科和多腺藤壶科两个科三个属的9种根头目藤壶。分子序列的系统发育分析揭示了该属中的两个新物种候选者，并且有三个物种（、和）被转移到了属。对宿主范围的研究表明，与来自其他地理区域的根头目藤壶相比，韩国根头目藤壶物种具有更高的宿主特异性和更低的感染率。这是基于形态学和分子分析对韩国寄生根头目藤壶的分类学、物种多样性和宿主范围的首次报道。为了全面了解它们的分类学、在十足目宿主上的流行情况以及主要根头目分类群之间的系统发育关系，有必要从广泛的甲壳类宿主物种中对寄生藤壶进行大量采样以获取更多信息。
