The First Records of Peltogastrid Rhizocephalans (Crustacea: Cirripedia: Rhizocephala) on Hermit Crabs (Paguroidea) in Taiwan and Differences in Prevalences among Collection Sites
並列摘要
From collections of 3073 individual hermit crabs in Taiwan, representing 56 species, 53 individuals of 3 different species were found to be infested by 3 species of rhizocephalans: Peltogaster postica on Pagurus angustus, Septosaccus cf. snelliusi on Diogenes tumidus, and Dipterosaccus indicus on Calcinus morgani. Rhizocephalans were identified based on histological sections, and species identifications were consistent with partial sequences of the cytochrome c oxidase subunit I (COI) gene. This is the 1st record of peltogastrid rhizocephalans (Crustacea, Cirripedia) from Taiwan. The prevalence of peltogastrid species greatly differed among the collection sites, and hosts for Pel. postica and Dip. indicus differed from previously known hosts in the Ryukyus and other sites. The microhabitat of the host species may be crucial to rhizocephalan parasitism success.
