A taxonomic study of the family Electridae Stach, 1937 (Bryozoa: Cheilostomatida) was carried out using materials collected from six localities of Korea from 1984 to 2021. Aspidelectra melolontha (Landsborough, 1852) is newly added to the bryozoan fauna of Korea, and Electra jindoica n. sp. is new to science. European A. melolontha is known to occur in brackish water of low salinity, but the species is found in New Zealand and Argentina seawater. This species is also reported as a fouling bryozoan from China and New Zealand. Electra jindoica n. sp. is distinguished by smaller zooid, larger kenozooid, and developed cryptocyst from E. asiatica Grischenko, Dick and Mawatari, 2007. With the addition of two species reported herein, six species and four genera of Electridae from Korea have been recorded: Aspidelectra melolontha, Arbopercula tenella, Conopeum hexagonum, C. reticulum, C. seurati, and Electra jindoica n. sp. Furthermore, the genera Aspidelectra and Electra are new to the Korean bryozoan fauna based on this study.

This study was conducted as a basic data for preparing future management alternatives by analyzing the status and characteristics of invasive alien plants by land-use type based on the formation of a new town in Goyang Siksa district. As a result, the invasive alien plants in the Goyang Siksa district were 20 families 46 genera 57 taxa; according to the land-use type, the residential area(Wi City apartment complex) is 7 families 10 genera 12 taxa, the public facilities area(Dongguk University campus) is 17 families 40 genera 47 taxa, the mixed forest is 5 families 10 genera 10 taxa, the rice paddy is 5 families 6 genera 7 taxa, river(Mt. Gyeondal creek) is 7 families 13 genera 15 taxa were appeared. The life-form of invasive alien plants in Goyang Siksa district is annuals, the origin is America, the introduction time is third period(1962~the present), and the diffusion grade is wide spread(5 grade) species. It was higher than other types. The naturalization index by location was 31.9% in river(Mt. Gyeondal creek), 21.2% in rice paddy, 16.7% in mixed forest, 15.5% in public facilities area(Dongguk University campus), and 8.5% in residential area(Wi City apartment complex). As a result of comparing the naturalization index by regions with the previous studies, it is judged that there are differences due to the environment such as urbanization progress, size, area, population inflow and location conditions. Although many new towns have been established to date, there is a lack of research on flora (including invasive alien plants) as a basic data for preparing management alternatives. Therefore, Through this study, basic data on the management of exotic plants by land use unit in urban areas can be provided.

The perciform suborder Labroidei comprising six families (Cichlidae, Embiotocidae, Pomacentridae, Labridae, Odacidae, and Scaridae) are characterized by having the specialized pharyngeal jaws for food processing, i.e., united fifth ceratobranchials and upper pharyngeal jaw articulating with the basicranium via diarthroses (Stiassny and Jensen, 1987). They usually inhabit in the most tropical and subtropical seas and comprise about 235 genera and roughly 2,274 species worldwide (Nelson, 2006). Concerning the Korean labroid fishes, Mori (1952) had listed 18 genera and 26 species belong to four families in his check list of Korean fishes since Jordan and Metz (1913) firstly reported six genera and seven species in only two families (Embiotocidae and Labridae). Chyung (1977) added two species, Tilapia mossambica and Cirrhilabrus temmincki, to Mori’s list and also classified them into three suborders, i.e., Embiotocina (containing only Embiotocidae), Pomacentrina (Cichlidae and Pomacentridae), and Labrina (Labridae and Scaridae). Subsequently, Lee and Kim (1996) reviewed the Korean labroidfishes taxonomically resulting in 22 genera and 32 species in five families with some taxonomical modifications including a new Korean record. It is remarkable to be added many new Korean recordsto the pomacentrids or the labrids for recent 10 years (Koh et al., 1995; Yoo et al., 1995; Koh et al., 1997; Myoung, 1997; Choi and Kim, 2000; Choi et al., 2002; Kim and Go, 2003). Recently, Kim et al. (2005) briefly described all members of the Korean Labroidei with a color photograph or a figure, recognizing 27 genera and 42 species in five families. In the present study, the current taxonomical status of the Korean labroid fishes including distributional features is summarized based both on specimens collected from the Korean waters and on literature survey to provide bio-information of the Korean native fish species. As a result, the Korean labroid fishes totally consist of 27 genera and 44 species in five families, that is, Cichlidae (1 species), Embiotocidae (3), Pomacentridae (15), Labridae (22), and Scaridae (2). They distributed mainly in the coastal waters of the South Sea, Korea, however, most pomacentrids or labrids occur in the coastal waters of Jeju Island only, although some species were observed in their larval or juvenile stages only from coastal waters of the island. Interestingly, several species are expanding their distribution north to Ulreung and Dok islands in the East Sea, Korea lately.

Twelve new species of two genera Smenospongia and Cacospongia (Demospongia: Dictyoceratida: Thorectidae) are described from Gageodo Island and Ulleungdo Island, Korea. Of these, ten new species of the Smenospongia are distinguished from the other nine reported species of the genus by the skeletal structure and sponge colour. Primary fibres of the genus Smenospongia are mostly dense, dark colour, and invisible inside of fibres, but they are mostly cored detritus and echinated with spicules. Especially, the end of primary fibres at the surface shows densely cored with spicules. All these new species changed the colour. Two new species of the genus Cacospongia are compared with nine other reported species. In skeletal structure, primary fibres of the genus Cacospongia are light colour, visible inside and more heavily cored with spicules and sands. The skeleton of this genus has large meshes. The colour of the genus Cacospongia does not change.

Six new species of copepods associated with polychaetes are described from Korea. Included are Indoclausia bipartita n. sp., Clausia parva n. sp., and Maxilliclausia propria n. gen. n. sp. in the Clausiidae; Pseudanthessius excertus n. sp. in the Pseudanthessiidae; and Polyankylis ovilaxa n. sp. and Sewelloya plana n. gen. n. sp. in the Polyankyliidae. The new genus Maxilliclausia has a peculiar maxilla in which the distal segment forms a sucking disk, a non-prehensile antenna, vestigial legs 3 and 5, and lacks a maxilliped and leg 4. The two new species of the Polyankyllidae are discovered as external associates of terebellid polychaetes. The new genus Sewelloya has a simple female maxilliped bearing only two small setae on its terminal segment, an uniramous leg 4 bearing 1-segmented exopod, and a reduced leg 5 represented by three setae. The genera Terebelliphilus Kim, 2001 which was originally placed in the Sabelliphilidae, and Octophiophora Stock, 1988 and Stockia Sebastian and Pillai, 1974, both of the latters with uncertain familial positions, are transferred to the Polyankyliidae. A key to five genera of the Polyankyliidae are provided.

Two new species belonging to the genera Microdrosophila and Drosophila, collected from Daegwallyeong and Mt. Halla in Korea are described with illustrations of the male genitalia. Microdrosophila (Microdrosophila) gangwonensis n. sp. seems close to M. (M.) purpurata Okada, 1956, but the new species has different phallic organ. Drosophila (Drosophila) taekjuni is close to D. (D.) brevitabula Zhang and Toda, 1992, in form, but differs in the shape of aedeagus. Eight species of the genus Microdrosophila and five species in the D. immigrans species-group of genus Drosophila, including the new species are known to be distributed in Korea.

The morphology, taxonomy, and distribution of species belonging to the diatom family Rhizosoleniaceae were studied from the marine coastal waters of Korea. Rhizosolenid diatom taxa were collected at 30 sites from September 2008 to February 2010 and were analyzed by light and scanning electron microscopy. We identified 6 rhizosolenid genera, including Rhizosolenia, Proboscia, Pseudosolenia, Neocalyptrella, Guinardia, and Dactyliosolen. We describe 5 genera in this study, except Rhizosolenia. Five genera were compared in detail with congeneric species. Six genera within the family Rhizosoleniaceae were divided into two groups based on morphological diagnostic characters including valve shape, areolae pattern, the shape of external process, and girdle segments in the column. The first group had a conoidal valve and loculate areolae, which comprised Rhizosolenia, Proboscia, Pseudosolenia, and Neocalyptrella, and the second group of Guinardia and Dactyliosolen showed a flat or rounded valve and poroid areolae. Important key diagnostic characters were based on valve shape, areolae pattern on the segment, external process, position of the tube, and the valve margin. D. phuketensis was new to Korean coastal waters.
