Five newly recorded species of cyanobacteria in Korea are Sphaerospermopsis reniformis(Aphanizomenonaceae) from Chungju-si, Chungcheongbuk-do; Pelatocladus maniniholoensis (Hapalosiphonaceae) from Ulleung-gun, Gyeongsangbuk-do; Tolypothrix carrinoi (Tolypothrichaceae) and Myxacorys chilensis (Leptolyngbyaceae) from Suwon-si, Gyeonggi-do; and Tildeniella torsiva (Oculatellaceae) from Gunsan-si, Jeollabuk-do. These species are morphologically similar to each of its corresponding type species, and clustered in the same clade with respective type species in the phylogeny using 16S rRNA. The similarity of 16S rRNA sequences was more than 98.5% with each of its respective type species.

Araeosoma owstoni Mortensen, 1904, a newly recorded sea urchin, was collected from the Korea Strait by trawling during a research expedition in April 2017. The specimen was damaged and was severely peeled off on the aboral side during trawling. However, a test and the surface of the oral side of the sample were well preserved, allowing us to successfully identify it. The species was distinguished by the large and flexible test, the tiny apical section, and the interambulacra width which is twice of the ambulacra. Pedicellaria tridentate and triphyllous were presents, but tetradactyle pedicellaria was absent due to severe peeling on the aboral side. Moreover, a length of 1,212 bp sequence from mitochondrial COI gene was obtained and this sequence covered the general DNA barcoding region. The mean of interspecific divergence within A. owstoni from Korea and other eight species of Araeosoma from the GenBank was 6.8%. This value indicated that our species was clearly distinguishable from the others. Thus, the first Araeosoma species occurring in South Korea is presented in this study.

A newly recorded species, Boehmeria nakashimae Yahara, is confirmed for the first time to be distributed on forest edges on Jejudo Island, Korea. This species is known to be endemic to northern Kyushu, Japan. It is characterized by ovate to broadly ovate, elliptic-ovate, or sub-orbicular middle leaf shapes, serrulate-dentate and uniform margins, 17-29 teeth on one side, a short caudate or narrowly acute apex, dense glomerules at fruiting, and densely strigillose on the stems, both surfaces of the leaves, the perianth of staminate flowers, and achenes. Therefore, it is given the new name 'Je-ju-top-mo-si-pul' in Korean based on its serrulate-dentate leaf margin and geographical distribution. A description, photographs, illustrations, and keys of related taxa in Korea are provided.

A faunal study on Amphipods belonging to the class Malacostraca was conducted 26-29 August 2021 at 12 sites in Chujado Island, Korea. This study found that 68 amphipod species in 39 genera, 19 families were living on Chujado Island. Among these 19 families, the family Caprellidae (20 species) showed the highest abundance. Ampithoidae (7 species) and Dexaminidae (6 species) were subdominant families. The species Stenothoe valida Dana, 1852 (found at 10 of 12 sites) was the most frequent and widespread species. Caprella scaura Templeton, 1836 was identified at 9 of 12 sites and had the highest frequency of appearance among 20 species of Caprellidae. Among the 68 species, Ampithoe waialua J.L. Barnard, 1970 and Melita nagatai Yamato, 1987 are newly recorded species in Korean fauna. These newly recorded species are fully illustrated and compared with related species. We provide an amphipod fauna in Chujado Island with a list, figures, and a table.

The region of the marine environment between shallow waters and deep-sea (30-150 m in depth) is referred to as the twilight or mesophotic zone. This zone has been scarcely examined, as these depths are too shallow for safe submersible operation. Since 2018, a survey of mesophotic echinoderms in Korea has yielded many specimens of interest. In this study, we present two newly recorded echinoderms, Henricia irregularis and Parastichopus nigripunctatus based on morphological redescriptions with high-definition photographs and DNA barcoding data for P. nigripunctatus.

The genus Eumetriochroa Kumata & Kuroko, 1988 has been known as a small genus with twelve described species worldwide. In this study, we aimed to review the Korean species of the genus Eumetriochroa of the subfamily Oecophyllembiinae, which belongs to the family Gracillariidae. Three species of this genus are recognized from Korea. Among them, two species, Eumetriochroa araliella Kobayashi, Huang & Hirowatari, 2013 and E. hiranoi Kumata, 1998 are reported for the first time from Korea. All the known species were enumerated with their available information and briefly redescribed for the newly recorded species. The adults and genitalia of all the species are redescribed and illustrated.

This study newly records a deep-sea coral, Flabellum (Ulocyathus) deludens from Korea. The specimens were collected by trawling at a depth of 100 m off Jejudo Island in 2019. The newly recorded species is described and compared with the other similar consubgeneric species in detail based on morphological characteristics, including corallum size, calicular diameter, calicular edge, face angle, edge angle, and septal arrangement. Flabellum(Ulocyathus) deludens is characterized by its solitary, highly compressed, wedge-shaped corallite with a small cylindrical pedicel, radiating inverse chevron-patterned lateral stripes on thecal faces, highly jagged calicular edges, and hexameral septal arrangement in five cycles. As a result of this study, five species in the family Flabellidae have been recorded from Korea.

A newly recorded species, Sinocorophium dongtanense, of the genus Sinocorophium was collected from shallow waters of Korea. This species was previously reported as S. homoceratum in Korea. However, after reanalysis of previously studied samples, this species was identified as S. dongtanense, which had previously been reported from the Yangtze estuary, Shanghai, China in 2014. In this study, the newly recorded species is illustrated with a diagnosis and compared to the previously misidentified species. Molecular phylogenetic studies for Sinocorophium species in Korea are provided. A key to the Sinocorophium species in Korea is also provided.

This study introduces a newly discovered brittle star, Amphiophiura megapoma, from the mesophotic zone in the East Sea, Korea. It is the second species belonging to the genus Amphiophiura (which includes 57 species) to be recorded in Korean waters after A. sculpta. The specimen was discovered during a September 2022 survey, by SCUBA diving in the upper mesophotic zone of the East Sea, Korea. This study presents the morphological characteristics of A. megapoma, highlighting its differences from the related species within a comprehensive taxonomic description. It provides high-resolution images of A. megapoma and a taxonomic key for Amphiophiura species in Korea.

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.
