Three heterotrophic euglenids from marine water column (Seodo port, Yeosu) and freshwater sediment (Seodong-chun, Incheon), Korea were identified as Entosiphon oblongum Cavalier-Smith and Vickerman, 2016; Euglena longa (Pringsheim, 1936) Marin and Melkonian, 2003; and Keelungia pulex Chan and Moestrup, 2013 based on morphological characters and 18S rDNA sequence analysis. These species are reported taxonomically for the first time from Korea and are described with micrographs. Diagnoses of these species are as follows. Entosiphon oblongum: phagotrophic, gliding, size in vivo, 23.1-29.3 ㎛ (Avg. 26.5 ㎛, n=30) long, ovate with a protrusive feeding siphon (apparatus), several deep grooves and two heterodynamic flagella. Euglena longa: osmotrophic, swimming, size in vivo, 32.3-52.2 ㎛ (Avg. 42.2 ㎛, n=26) long, elongated with many paramylum granules and two flagellar. Keelungia pulex: phagotrophic, gliding, size in vivo, 13.5-19.7 ㎛(Avg. 16.4 ㎛, n=97) long, oblong to ovoid with a hook-shaped ingestion apparatus, several dorsal ridges and two flagella.

We report a zygaenid moth, Inope heterogyna Staudinger for the first time from Korea. This species which shows the dark brown wings without medial lines and markings, is externally indistinguishable from Inope maerens and the correct identification can be done by the genitalia examination. The female genitalia of Inope heterogyna can be distinguished by the relatively short and strongly coiled at the anterior ductus bursae.

Four species of the free-living nematodes were collected from marine sediments in the sublittoral zone in the East Sea, Korea and were identified, described, and illustrated. Paranticoma tricerviseta Zhang, 2005, originally described from the Bohai Sea, China, is recorded for the first time in the East Sea, Korea; only in body length and thickness (1902-2282 ㎛ compared to 2472-3300 ㎛, 50-62 ㎛ compared to 57-82 ㎛, respectively). Specimens of Parodontophora marina Zhang, 1991, from East Sea, Korea largely agrees with the original description of Zhang (1991) of nematodes from the Bohai Sea, except for differences in body length and thickness (1190-1345 ㎛ compared to 1235-1408 ㎛, 40-44 ㎛ compared to 42-72 ㎛). Terschellingia longicaudata de Man, 1907 is reported for the first time in Korea, but was previously considered a cosmopolitan species of nematodes with a widespread distribution from the North Sea, Belgium to the Exclusive Economic Zone of New Zealand; it differs from the original description in body thickness(30-38 ㎛ vs. 40-62 ㎛). Vasostoma brevispicula Huang & Wu, 2011, originally described from the subtidal muddy sediment in the Yellow Sea, China, is newly reported in Korea; apart from a few minor morphological differences, body length and thickness (2009-2425 ㎛ vs. 2119-2906 ㎛, 41-48 ㎛ vs. 37-58 ㎛). The present study on unrecorded species improves our understanding of nematode species diversity in Korean waters.

The joint faunal survey of Jindo Island, Korea was performed by the Korean Society of Systematic Zoology during June 29-July 1, 2004 in commemoration of the 20th anniversary. In this study, 20 echinoderm species of 13 families, ten orders in four classes such as one crinoid species, seven asteroid species of four families in three orders, five ophiuroid species of three families in two orders, four echinoid species of two families in one order, and three holothuroid species of three families in three orders collected from six localities (Bealpo, Chopyung, Supum, Hoedong, Seomang, and $34^{\circ}11'N\;and\;126^{\circ}21'E)$ were identified. Of these, one crinoid (Antedon serrata), two asteroids (Solaster dawsoni and Distolasterias nipon) and one pohiudoid (Astrodendrum sagaminum) are newly added to the echinoderm fauna of Jindo Island and one holothudoid (Pseudocnus sp.) is newly recorded in Korean waters. The total 31 species are presently listed with some brief remarks and their distribution patterns are discussed based on the composition of geographical distribution forms.

Some sea urchins were collected from the subtidal rocky bottom along the coastal line in Jeju Island by SCUBA diving in April 2005 and identified on the basis of their morphological characteristics. Among them, Asthenosoma ijimai Yochiwara, 1897 was newly recorded from Korea and redescribed based on the specimen collected at 20m deep in southern breakwater of Seogwipo harbor. The order Echinothurioida including family Echinothuriidae and genus Asthenosoma was firstly recorded in Korea. Seventeen species of echinoids are reported to be distributed in Jeju Island of Korea.

One marine ciliate, Diophrys quadrinucleata Zhang et al., 2020 was newly recorded from South Korea in this study. We provided morphological diagnosis and images of the Korean D. quadrinucleata population. We determined the small subunit ribosomal DNA (SSU rDNA) and cytochrome oxidase subunit I (CO1) sequence data of D. quadrinucleata, and then the sequences were compared with other Diophrys species. Intra-specific variation between the Korean and type (Chinese) populations was identical in the SSU rDNA, while the inter-specific variations between seven Diophrys species were 0.3-3.8% in the SSU rDNA and 12.6-18.2% in the CO1. In this study, we obtained 18S and CO1 data from species with identified morphology. As the importance of securing 18S and CO1 based on morphology increases in current studies, this study will contribute to ciliate studies.

Samples were collected between August 2016 and May 2017 at Sangju-si, Gyeongsangbuk-do, Jeju-do, and Uljin-gun, Gangwon-do. As a result, one genus and six species were newly recorded in Korea. The unrecorded indigenous genus was Borzia, and the six species were Anagnostidinema acutissimum, Komvophoron bourrellyi, Hydrocoleum stankovicii, Borzia trilocularis, Phormidium tinctorium and Pseudanabaena lohchoides. Phormidium tinctorium and Pseudanabaena lohchoides had been reported to inhabit freshwater, but in this study, these were found in brackish water. It had also been reported that B. trilocularis trichomes are composed of up to 8 cells, but in this study, a maximum of 10 cells was observed.

Plastic wastes have a negative impact on marine environments; however, they can be used as carbon sources and habitats by certain microbes. Microbes in the marine plastisphere can migrate worldwide through the ocean and cause serious environmental problems when they encounter suitable environments. Therefore, efforts to investigate the microbes inhabiting the marine plastisphere are increasing. In the present study, fungal strains were isolated from plastic wastes buried in Korean sea sands and mudflats and identified using molecular and morphological analyses. Five species were identified that were previously unrecorded from South Korea: Cladosporium funiculosum, Neosetophoma poaceicola, Neosetophoma rosigena, Parasarocladium gamsii, and Trichoderma fomiticola. Their molecular phylogenies and morphological characteristics are described in this study.
