A harpacticoid copepod, Microarthridion littorale (Poppe, 1881), is newly recorded in Korea. Microarthridion species can be distinguished from each other by a combination of the number of the antennular segment, the number of the seta on the antennary exopod, and the armature of the thoracopod legs. Korean materials examined coincide well with M. littorale on these well-known characteristics. However, there are some minor differences in the ornamentations of the maxilliped and swimming legs. The specimens show additional sexual dimorphisms in the setae on enp-3 of P1 and exp-3 of P2-P4. Morphological diversity of so-called M. littorale is also discussed here with detailed features.

The genus Mesyatsia Ricker & Ross, 1975 is a small genus of the family Taeniopterygidae with only six species worldwide. This genus is mainly distributed in Asia, but has never been reported in Korea. In this paper, we report Mesyatsia makartchenkoi Teslenko & Zhiltzova, 1992 for the first time from the Korean Peninsula. The specimens were collected from Odaesan National Park, Bangtaesan Natural Recreation Forest, and Gariwangsan Natural Recreation Forest in Gangwon-do, South Korea by mainly Malaise traps and a few by sweep net. Some pharate larvae and adults crawling on the snow were also collected by handpicking. This species is characterized by the following features: pterostigma with dark spots; abdominal sternum 9 with vesicle; abdominal tergum 10 medially divided into two; subgenital plate strongly elongated, scoop-shaped, upcurved with tongue-shaped apex; cercus blunt. We provide materials, diagnosis for newly recorded species, and distributions. Additionally, we include a provisional key to the genera of Taeniopterygidae from Korea based on males.

Twelve species of cyclopoid copepods, including two new genera and ten new species, associated with polychaetes are described from Korea. The new taxa comprise Petalocopus planus n. gen. n. sp. in the Clausidiidae, Rhodinicola exilis n. sp. in the Clausiidae, Gastrodelphys vadicola n. sp. in the Gastrodelphyidae, Polyankylis estivalis n. sp. in the Polyankyliidae, Pentakela cylindrica n. gen. n. sp., Pseudanthessius oporinus n. sp. and P. petilus n. sp. in the Pseudanthessiidae, and Myxomolgus buanensis n. sp., M. dokdoicus n. sp. and Serpuliphilus antennatus n. sp. in the Sabelliphilidae. As characteristic features of the new genera, Petalocopus n. gen. has a pair of pedunculate suckers on the terminal segment of the antenna and an enlarged posterodistal seta on the second segment of antennule, and Pentakela n. gen. has five strong hooks on distal segments of antenna, three-segmented exopod and two-segmented endopod in legs 1 and 2, and one-segmented exopod and a lobate, rudimentary endopod in legs 3 and 4. The male of Maxilliclausia propria Kim, 2014 of the Clausiidae is recorded for the first time. Nereicola ovata Keferstein, 1863 known previously only in European waters is redescribed based on a newly collected female specimen from Korea.

Three marine heterotrophic flagellates from intertidal sediments of Gwang-Am beach and Garorim Bay, Korea were identified as Neometanema parovale Lee and Patterson 2014, Stephanopogon pattersoni Lee et al. 2014 and Thaumatomastix sp. These species are reported taxonomically for the first time from Korea, and are described with illustrations and micrographs. Diagnostics of these species are as follows. Neometanema parovale (Euglenozoa): size in vivo, $10{\sim}23{\mu}m\;long$ with 22 pellicular strips, ingestion apparatus barely visible by light microscopy and two flagella pointed in different directions when moving. Stephanopogon pattersoni (Percolozoa): size in vivo, $20{\sim}33{\mu}m\;long$, with 6 ventral and 1 ventro-lateral ciliary rows, and three barbs. Thaumatomastix sp. (Cercozoa): size in vivo, $14{\sim}17{\mu}m$ with body scales and spines, and two flagella with one naked and one scaled.

Two species of Apoglossum is newly recorded in Korea collected from subtidal habitats of Jeju Island. Apoglossum minimum Yamada has previously been known only from the coast of Japan. It is characterized by having corticated midrib but lacking microscopic veins. Apoglossum gregarium (Dawson) Wynne is reported for the first time from the north western coast of Pacific Ocean. It has been distinguished by its ecorticate midrib from the former species. Their morphological characteristics in detail and taxonomic issues are discussed.

Some crinoids collected by scuba divers from Jeju Island, Geomundo Island and Yokjido Island were identified. Of which two species, Oligometra chinensis A. H. Clark, 1918 belonging to the family Colobometridae and Neometra multicolor (A. H. Clark, 1907) belonging to the family Calometridae, order Comantulida, turned out to be new to the Korean fauna. The Calometridae was reported in Korea for the first time.

The present faunistic study, on the marine harpacticoids of Chindo Island, Korea was based on the materials collected from various habitats during the periods from October 23-24 in 1993and July 23-25 in 1994. As a result of examining the specimens, 9 species or subspecies of 6 families were identified , of which 6 species or subspecies were newly recorded from Korea : Tachidius (Tachidius) discipes Giesbrecht, 1881 : T.(Neotachidius) triangularis Shen and Tai, 1963 ; Scutellidium longicauda acheloides Ito, 1976 ; Alteutha depressa (Baird, 1837) ; Amonardia normani (Brady, 1872) ; Onychocamptus bengalensis (Sewell, 1934).

Two marine harpacticoid copepods are newly recorded from Korea : Eudactylopus specitabilis (Brian, 1923) and E. andrewi Sewell , 1940. Six species are currently recognized in the genus Eudactylopus, multitidue of which were often disputed among authors on their taxonomic status, so we treat here the taxonomic features of the two species above on the basis of specimens from South Sea and East Sea of Korea. E.spectabilis occurred first outside the Mediterranean Sea. and is fully redescribed with illustrations. Important male characters like the shape of leg 2 endopod and leg 5 with its setal arrangement are particularly emphasized as the diagnostic characters.

An asteroid specimen was collected by using a fishing net from the waters near Daejin harbor, in the East Sea of Korea on 3 Mar 2017. Based on morphological characteristics, the specimen was identified as Aleutihenricia beringiana (Djakonov, 1950), belonging to the family Echinasteridae, of the order Spinulosida. The genus Aleutihenricia was first described by Clark and Jewett, 2010. This species can be distinguished from other Aleutihenricia species by having a roundish protruding shape of abactinal and actinal plates, the number of abactinal spines bearing three to eight spinelets, and the number of adambulacral spines comprising six to eight spinelets. This is the first report of the genus Aleutihenricia and A. beringiana in Korea.
