A New Record of Paramphicteis weberi (Polychaeta: Terebellida: Ampharetidae) in Korean Fauna

초록

An ampharetid polychaete, Paramphicteis weberi (Caullery, 1944), originally described from Indonesia, is newly reported from Korean waters. Paramphicteis weberi is characterized by the presence of the prostomial glandular ridges, nuchal ridges, pinnate buccal tentacles, four pairs of the foliose branchiae, and paleae in segment II. The mitochondrial cytochrome c oxidase subunit I(COI), 16S ribosomal DNA(16S rDNA), and nuclear 18S ribosomal DNA(18S rDNA) sequences from the Korean specimens of P. weberi were determined. The intra-specific genetic distance was 0.0- 0.2% in COI and no variation was detected in 16S rDNA and 18S rDNA. The inter-specific genetic distances between several Amphicteis species were 20.0-22.0% in COI, 15.3-20.4% in 16S rDNA, and 1.3-3.1% in 18S rDNA. This is the first record of the genus Paramphicteis Caullery, 1944 in Korean fauna.
