  • We performed a taxonomic study on Korean freshwater bryozoans with the materials collected from 70 localities during 2014 to 2016. A total of 14 Korean freshwater bryozoans are reported through this study. Among them, three Plumatellids, Plumatella fungosa (Pallas, 1768), P. repens (Linnaeus, 1758), and P. reticulata Wood, 1988, are newly added to the Korean fauna. Three species were redescribed with only their statoblasts: Lophopodella carteri, Plumatella rugosa, and Stephanosella hina (Seo, 1998; 2005; Chae et al., 2016). Their colonies were found in Korea for the first time in this study. Since Fredericella sultana, Hyalinella punctata, and Plumatella casmiana were reported from Korea (Toriumi, 1941), neither statoblast nor colony has been found, but we observed them. Living colonies of six species were photographed in the field. Furthermore, the statoblasts of nine species, including three species new to the Korean fauna, were also documented using scanning electron microscopy.

  • Examining the polychactous annelids collected from Tongyeong Bay and Gwangyang Bay, I found three species which should be added in tile list as new to the polychaetous annelid fauna of Korea. In the present study three species are reported with morphological descriptions. Consquently, a total of 128 species of polychaetous annelids has been reported (Kamita and Sato, 1941; Paik, 1972, 1973a, 1973b; Rho and Song, 1974, 1975: Paik, 1975a, 1975b, 1976: Lee, 1976; Paik 1977, 1978, 1979a,1979b) in Korea.

  • This study describes a new species of cytheroid ostracod, Paradoxostoma koreana sp. nov., collected in Korea. In addition, three other cytheroid ostracods, P. setoense Schornikov, 1975, Loxoconcha pulchra Ishizaki, 1968, and Ishizakiella miurensis (Hanai, 1957), are reported with brief descriptions and images. Paradoxostoma setoense and L. pulchra were previously only known from Japan, while I. miurensis was previously reported from Korea. Here, we describe variability in hemipenis morphology observed in the Korean population. The new species is closely related to several East Asian species, but its sister species is P. rhomboideum Okubo, 1977. The primary difference between the new species and P. rhomboideum is morphology of the distal projections of the hemipenis, but minor differences exist in the details of the cheatotaxy of other appendages. This report also provides a list of all East Asian Paradoxostomatidae.

  • Twelve species of siphonostomatoid copepods mainly associated with marine invertebrates are recorded from Korean waters. Nine species are new to science: Arctopontius minutus n. sp., A. adelphus n. sp, and Dyspontius alatus n. sp. in the family Artotrogidae; Asterocheres horridus n. sp., A. cuspis n. sp., A. quadridens n. sp., Scottocheres mipoensis n. sp., Asteropontoides acutirostris n. sp. and Callomyzon macrocephalus n. gen. n. sp. in the family Asterocheridae. The new genus Callomyzon is distinguished from other genera in the family by having six setae on the third endopodal segment of leg 3, four spines and three setae on the third exopodal segment of leg 4 and three setae on the third endopodal segment of leg 4. Three new records of Korea, Asterocheres lilljeborgi Boeck, 1859 and A. simulans (T. Scott, 1898) in the Asterocheridae, and Parartotrogus arcticus T. and A. Scott, 1901 in the Cancerillidae are redescribed as the circum-Arctic species.

  • We report three new records Korean marine gastropods. The new record species are Hipponix acuta, Lyncina (Ponda) carneola, and Velutina (Velutella) plicatilis cryptospira. As a result, the family Hipponicidae in Korea turned out to be 5 species of 4 genera, Cypraeidae are 14 species of 8 genera, and Velutinidae are 7 species of 3 genera, respectively.

  • Foraminifera are protists that inhabit diverse marine environments and show high abundance and diversity. However, previous studies on foraminifera in Korea mostly focused on geological and paleoecological fields and were conducted in a limited area. Therefore, there is a high possibility for discovering new and unrecorded species. Here we describe three newly recorded foraminiferal species from the southwestern part of Jeju Island during a survey on the meiofaunal community, which belongs to three different genera (Ammobaculites, Cylindroclavulina, Saracenaria), three families (Lituolidae, Vaginulinidae, Valvulinidae), and three orders (Lituolida, Textulariida, Vaginulinida): Ammobaculites formosensis Nakamura, 1937, Cylindroclavulina bradyi (Cushman, 1911), and Saracenaria hannoverana (Franke, 1936). These species have been reported from Chinese region in the East China Sea, however this is the first report from Korean waters. Particularly, Cylindroclavulina bradyi is the first report of the genus Cylindroclavulina in Korean waters. The present study supports the diversity of foraminiferal species in Korea, and the necessity of further surveys in Korean waters.

  • Three new species of Collocheres are described as associates of crinoid and ophiuroid echinoderms from Cheju Island, Korea: Collocheres brevipes n. sp. from the crinoids Comanthus solaster A. H. Clark and Decametra tigrina (A. H. Clark); C. solidus n. sp. from two species of the crinoids Comanthus solaster and Comanthus japonicus (Muller) and one species of ophiuroid-Ophiomastax mixta (Lutken); and C. tamladus n. sp. from the crinoid Catoptometra rubroflava (A. H. Clack). The three species are distinguished from one another and other congeners by the body size, dimension of caudal ramus and free segment of leg 5, and shape and ornamentation of urosome.

  • A preliminary list of the following four tephritoid families is provided including 30 Korean species, of which 12 are new to Korea: two Lonchaeidae, three Pallopteridae (two new to Korea), 17 Platystomatidae (two new to Korea), and eight Ulidiidae (all new to Korea). This list is mainly based on the insect collection at the Yonsei University Wonju Campus and on previous publications concerning these taxa. Although a full taxonomic revision for each family is required in the long term, this preliminary list will provide a useful starting point to further investigation of these families. For the other three tephritoid families known in Korea but not treated in the present study, 89 species of Tephritidae, 14 species of Pyrgotidae, and one species of the rare family Ctenostylidae have been reported previously. A total of 134 species in seven families are officially recognized for the Korean fauna of the superfamily Tephritoidea.
