Dinoflagellate species composition has changed around Jeju Island as well as in Korean waters due to global warming and climate changes. An investigation was conducted to monitor changes in planktonic dinoflagellates around Jeju Island from June 2006 to September 2009. A total of 86 species belonging to 14 families and 15 genera were identified, of which 34 species were newly recorded in Korean waters. Among the newly recorded species, >20 were confirmed as tropical species. Thus, the occurrence of such tropical dinoflagellates could be an indicator to monitor of environmental changes including global warming around Jeju Island and in Korean waters.

A newly recorded species Caprella arimotoi Takeuchi, 1993, belonging to the family Caprellidae Leach, 1814, was collected from the South Sea, Korea. This species is morphologically very similar to Caprella verrucosa Boeck, 1871, with blunt dorsal projections on pereonites, oval-shaped propodus on gnathopod 2, and grasping spines on the pereopods 5-7. Caprella arimotoi originated from C. verrucosa and are difficult to distinguish because they have mixed characteristics. However, C. arimotoi was classified because of several morphological differences. The newly recorded species C. arimotoi is discernible from C. verrucosa by a forwardly curved anterodorsal projection on head, elongated gills, slender pereopod 7, and lacking ventrolateral projections on pereonites 2-7. To date, C. arimotoi has only been reported in Japanese waters. So, our record is the first record in Korean waters and outside of Japan. In this study, the Korean C. arimotoi is illustrated based on the mature male specimens with a brief description of the female, focusing on the sexually dimorphic characters.

The species Socarnes bidenticulatus japonicus Gurjanova, 1962 belonging to the family Lysianassidae Dana, 1849 has been collected from Namae, on the east coast of Korea. The genus Socarnes Boeck, 1871 has 12 species worldwide. However, only one Socarnes species had been reported in Korea until now: S. tongyeongensis Kim & Hendrycks, 2013. This genus is characterized by a longer article 2 of mandibular palp, unconstructed inner ramus of uropod 2, biarticulated outer ramus of uropod 3, and deeply cleft telson. A newly recorded species S. bidenticulatus japonicus is characterized by a posteriorly bidentated epimeron 3 and constricted inner ramus of uropod 2. The species is described and fully illustrated in this study.

A total of 56 genera and 101 species of the fly family Tephritidae have been previously recorded in Korea. As a result of an ongoing study of this family, I report the following ten additional species new to Korea: Actinoptera montana (Meijere, 1924), Actinoptera reticulata Ito, 1984, Campiglossa luxorientis(Hering, 1940), C. melanochroa (Hering, 1941), C. quadriguttata (Hendel, 1927), C. shensiana (Chen, 1938), Oxyna gansuica Wang, 1998, Tephritis jocaste Hering, 1953, Tephritis okera (Shinji, 1940), and Trupanea guttistella (Hering, 1951). Among the five genera involved here, the genus Actinoptera Rondani, 1871 is recognized for the first time in Korea. Therefore, 57 genera and 111 species are now officially recognized for the Korean tephritid fauna. For each newly recognized Korean species, I provide new Korean name, synonymy, taxonomic diagnosis and color photographs. When possible, I list the host records and discuss their intraspecific variability and sexual dimorphism.

Mt. Taebaeksan extends from Gangwon-do Province (Taebaek-si, Youngwon-gu, and Jeongseon-gun) to Gyeongsangbuk-do Province (Bongwha-gun), South Korea. Indigenous fungi present in the park were investigated between 2019 and 2022. All collected specimens were identified to the species level based on their morphological characteristics and molecular phylogenetic analysis using sequences from the internal transcribed spacer (ITS) and large subunit (LSU) of ribosomal DNA. Among them, 17 species-Cyanosporus bifarius, Dacryobolus angiospermarum, Entoloma sericeum, Flammulina rossica, Fuscopostia leucomallella, Homophron helvolescens, Hygrophorus queletii, Hymenochaete huangshanensis, Inocybe albodiscoides, Lactarius fulvihirtipes, Lepiota ignivolvata, Physisporinus eminens, Ramaria gracilis, Russula albolutea, Russula cremicolor, Stropharia lignicola, and Tengioboletus subglutinosus-were newly recorded macromycota in Korea.

A taxonomic review of the Korean Lycocerus (Cantharidae, Coleoptera) was presented. Through this study, total of four species were found from Korea including a species new to Korea, Lycocerus striatus. We newly provided a key to the Korean Lycocerus species and the distributional map on each species in this study.

Lovenia elongata is a member of the family Loveniidae and is one of the most common tropical echinoids. This species has a broad distribution range in the sub- and tropical regions of the Indo-Pacific Ocean, extending from the Mozambique to the Hawaiian Islands, and from southern Japan to northern Australia. It is commonly found in subtidal areas and on coral reefs within these regions. This species was for the first time recorded from the Ulleungdo Island, Korea. This species is characterized by a teardrop-shaped test that reaches up to 5 cm in length, with a deep groove at the front and tapered at the back end. The petaloid is not obvious, and the primary spines are long and banded. This study is the first to report the newly recorded L. elongata in Korea.

A newly recorded species, Aora pseudotypica Hirayama, 1984, belonging to the family Aoridae Stebbing, 1899 was collected from Geomundo and Jejudo Islands in South Korea. This species is characterized by having large triangular process on basis of male gnathopod 1. It is morphologically similar to A. typica Krøyer, 1845, but distinguishable by the lack of a large rounded process on the anterior margins of basis and ischium on male gnathopod 1 and having small distal segment on outer ramus of uropod 3. To date, only two genera, Aoroides Walker, 1898 and Grandidierella Coutière, 1904, of the family Aoridae have been recorded in Korea, so this is the first record of the genus Aora from Korea.

Taxa in the order Chlorococcales inhabiting Hongcheon River, South Korea were collected and identified from December 2011 to September 2012. As a result, nine taxa in the Order Chlorococcales including unrecorded genera Oocystidium and Heleococcus were newly added to the Korean flora: Oocystidium ovale, Heleococcus mucicola, Chlorella mirabilis, Monoraphidium convolutum var. pseudosabulosum, M. minutum, Raphidocelis mucosa, Eutetramorus tetrasporus, Scenedesmus flavescens, and S. multicauda. The morphological characteristics of the nine taxa identified in this study mostly corresponded to already reported characteristics; however, M. minutum had a shorter cell length than the recorded description, Raphidocelis mucosa and S. flavescens were larger than previous descriptions, and Scenedesmus multicauda had larger spines than the cell itself. Eight of the nine taxa were found in planktonic samples, whereas Heleococcus mucicola was found in an epilithic sample. Therefore the Korean order Chlorococcales, including these newly reported ones, totals to 255 species.
