거제도의 십각류상을 밝히기 위한 분류학적 연구를 수행하였다. 그 결과 28과 79종이 동정되었으며, 이 가운데 새우류 9종, 집게류 7종, 게류 39종이 거제도의 십각류상에 추가되었다. 과거기록을 포함하여 총 93종의 분류목록을 마련하였으며, 기재없이 기록만 있었던 중간뿔물맞이게 (Pugettia quadridens intermedia Sakai, 1983)를 재기재 하였다. 또한 게류 64종의 분포형과 종의 출현양상을 근거로 거제도의 동물지리적 양상을 논하였다.

Two species of the agar-yielding genus Gelidium, G. galapagense and G. isabelae, have previously been reported from Korea but their occurrence has not been confirmed with molecular data. We intensively collected samples of Gelidium from Jeju Island, where the two species were reported, and the southern coast of Korea. Phylogenetic analyses based on cox1 and rbcL sequences revealed that only a single species occurred in Korea. The Korean species was distantly related to G. galapagense and G. isabelae from the Galápagos Islands, and formed a clade with G. microdonticum, G. millarianum, and G. pakistanicum. A new species, G. palmatum, is described for those specimens that were previously recognized as either G. galapagense or G. isabelae from Korea. G. palmatum is small in size (up to 0.7 cm), with compressed, lanceolate axes, irregular, digitate to palmate branches, abundant rhizines in the medulla, tetrasporangial sori without sterile margins, and rounded bilocular cystocarps borne subapically on palmate branchlets.

The genus Luidia belongs to the family Luidiidae in the order Paxillosida. It is a common littoral taxon, and the depth range of the Korean fauna is generally 0-100 m. However, specimens of Luidia were collected from Jeju Island in Korea at 150-160 m depth and identified as Luidia sagamina sagamina $D{\ddot{o}}derlein$, 1920. This species is determined by morphological characteristics and mitochondrial cytochrome c oxidase subunit I sequence analysis. Luidia sagamina sagamina is a very rare sea star in worldwide and it only collected previously from Sagami Bay, Japan, and is newly reported in Korea. Four species of Luidia, including L. s. sagamina, are recorded in the Korean fauna.

DNA barcoding of two marine tintinnids, Eutintinnus rectus and Schmidingerella arcuata, was performed using four samples collected from different sites in the north-eastern coast of South Korea. The loricae morphology was observed by light and scanning electron microscopy. Molecular data were analyzed using five nuclear ribosomal DNA markers(18S, ITS1, 5.8S, ITS2, and 28S genes) and one mitochondrial marker (CO1 gene). The intraspecific pairwise differences of E. rectus and S. arcuata in the CO1 gene were 0.0-0.2% and 0.0-0.6%, respectively, while there were no differences in the 18S rDNA sequences.

Jesogammarus (Jesogammarus) hinumensis Morino, 1993 was discovered firstly from a brackish water region in Jeju Island, Korea. To identification of the specimens we conducted both of morphological and molecular analyses. This species is characterized by having large eyes and a robust seta on the mandibular palp article 1. The morphology of this Korean specimens was well matched with the original description without variation. The mitochondrial cytochrome c oxidase subunit I(COI) sequences of the present specimens were also completely identical to the sequences of J. (J.) hinumensis collected from the type locality of the species. Thus, we concluded that the Jesogammarus species from Jeju Island is J.(J.) hinumensis, based on both morphological and molecular data.

The polychaete Scolelepis (Scolelepis) sagittaria was originally described from Japanese waters and subsequently reported from Korean waters. In this study, we determined for the first time the mitochondrial cytochrome c oxidase subunit I (COI), 16S ribosomal DNA (16S rDNA), and nuclear 18S ribosomal DNA (18S rDNA) sequences of Korean specimens of S. (S.) sagittaria. We also assessed intraspecific variation in the shape of the prostomium of this species based on an examination of 247 individuals. All materials were collected from intertidal sandy beaches of the Korea Strait. The molecular data and morphological observations reported herein will contribute to gaining a better understanding of the taxonomic relationships among members of the genus Scolelepis.

The magelonid polychaete Magelona parochilis Zhou and Mortimer, 2013 is newly reported from South Korea. The Korean specimens correspond well to the original description of M. parochilis in having prostomium without horn, mucronate chaetae on chaetiger 9, superior dorsal lobes on chaetigers 1-8, ventral neuropodial lobes on chaetiger 9, smooth edged thoracic notopodial lamellae, and unidirectional tridentate hooded hooks on abdominal chaetigers. Partial sequences of cytochrome c oxidase I (COI) and 16S ribosomal DNA (16S rDNA) of the species were determined from Korean specimens. The detailed description and illustrations are provided with partial sequences of COI and 16S rDNA as molecular markers for species identification.
