We report an unrecorded plant species, Elatostema laetevirens Makino (Urticaceae), in Korea. This species was collected for the first time from under the canopy of an evergreen forest in Hyodoncheon, Sanghyo-dong, Soeguipo-si and Tamra valley in Ohdeung-dong, Cheju-si of the Province of Cheju in Korea. E. laetevirens Makino was quite distinct from others of the genus Elatostema in Korea owing to its perennial nature, the absence of trichomes in the stem and the absence of peduncles during the inflorescence period. This species was given the Korean name 'pu-reun-mong-ul-pul' based on the absence of luster and the bluish green color on the adaxial surface of its leaves.

Bacterial communities inhabiting islands play a vital role in the functioning and formation of a unique, isolated ecosystem. Nevertheless, there has been a lack of systematic research on the indigenous microbiological resources of the islands in Korea. To excavate microbial resources for further studies on the metabolism and biotechnological potential, a standard dilution plating was applied to coastal seawater samples collected from islands along the west coast of the Korean Peninsula, including Deokjeokdo, Baengnyeongdo, and Daebudo in 2022. A total of 2,007 bacterial strains were isolated from the samples as single colonies and identified using 16S rRNA gene sequence analyses. A total of 20 strains, with ≥98.7% 16S rRNA gene sequence similarity to bacterial species having validly published names but not reported in Korea, were designated as unrecorded bacterial species in Korea. The unrecorded bacterial strains were phylogenetically diverse and belonged to four phyla, five classes, 12 orders, 17 families, and 18 genera. The unreported species were assigned to Algimonas, Amylibacter, Notoacmeibacter, Roseibium, and Terasakiella of the class Alphaproteobacteria; Alteromonas, Congregibacter, Marinagarivorans, Marinicella, Oceanospirillum, Psychromonas, Thalassotalea, Umboniibacter, and Vibrio of the class Gammaproteobacteria; Lutibacter and Owenweeksia of the class Flavobacteriia; Paenibacillus of the class Bacilli; and Pelagicoccus of the class Opitutae. The taxonomic characteristics of the unreported species, including morphology, biochemistry, and phylogenetic position are provided in detail.

We reported an unrecorded species of the genus Allium (Alliaceae) which is growing along riversides in the central part of Korean peninsula. A. longistylum Baker, has been known to distribute only in China. The new common name, 'Gang-bu-chu', was given considering the habitat characteristics such as growing riversides in Korea. In this study, we described morphological characters, and provided illustrations as well as photographs of the habitat.

The Korean muricid snails are listed include previous record and three unrecorded species, Morula iostoma, Coralliophila morishimai, and C. abnormis collected from Mudo of Jeju-do were redescribed. As a result, the family Muricidae in Korea turned out to be 44 species of 22 genera.

During a study to discover indigenous prokaryotic species in Korea in 2016, a total of 42 actinobacterial isolates were recovered from various environmental samples collected from natural cave, squid, sewage, sea water, trees, droppings of birds, freshwater, eelgrass, mud flat, sediment and soil. On the basis of a tight phylogenetic clade with the closest species and high level of 16S rRNA gene sequence similarity, it was shown that each isolate was assigned to independent and previously described bacterial species which were assigned to the phylum Actinobacteria. The following 42 species have not been reported in Korea: eight species in two genera n the order Corynebacteriales, 26 species of 16 genera in the Micrococcales, one species of one genus in the Micromonosporales, one species of one genus in the Propionibacteriales, four species of two genera in the Streptomycetales and two species of two genera in the Streptosporangiale. Cell morphology, Gram staining reaction, colony colors and features, the media and conditions of incubation, physiological and biochemical characteristics, origins of isolation and strain IDs of 42 unrecorded actinobacterial species are presented in the species description.

More than 100 samples of the Ascomycetous fleshy fungi were collected and inves­tigated. Among them, 3 genera and 9 species were confimed as unrecorded ones in Korea. Unrecorded genera were Tarzetta, Hypocrea and Mollisia. Unrecorded species were Cyathipodia villosa, C. cupuliformis, Cudonia confusa, Tarzetta catinus, T. cupularis, Rutsroemia petiolorum, Mollisia ventosa, Hymenoscyphus pileatus and Hypocrea rufa.

Family Coleophoridae, commonly known as "casebearers", is one of the largest families of Gelechioidea (Lepidoptera), with more than 1,450 described species worldwide, but it has been poorly known in Korea, with only 32 known species of the genus Coleophora Hübner, 1822. Here we present Coleophora fasciella Koo & Baldizzone, sp. nov., a new species to science, and C. mayrella (Hübner, [1813]), an unrecorded species in Korea. Diagnostic characteristics with descriptions of the genitalia are provided with photos of adults, wing venations, and genitalia of both sexes for the species. Mitochondrial cytochrome c oxidase subunit I(COI) barcode sequences for the two species are also provided.

Four species, Colpotrochia bifasciata, C. munda, C. pilosa sinensis, and C. uchidai, are newly recognized in South Korea. The genus Colpotrochia Holmgren, 1856 is a large group of the subfamily Metopiinae, in Ichneumonidae, and contains 62 described species worldwide. Among them, nine species have been recorded from South Korea. The South Korean Colpotrochia was started from by Uchida in 1930. A comprehensive historical review of the faunal study of this genus in South Korea have been done by Kim and Japanese entomologists in the period of 1955-1966. In this study, diagnoses of four unrecorded species and illustrations of diagnostic characters are provided. The current total is 13 species of this genus known from South Korea.

Foraminifera are unicellular eukaryotes widely distributed in marine and transitional marine environments. They play important roles in marine food webs and geochemical cycles and have physiological properties like the formation of calcareous tests and nitrogen respiration. Research on species diversity, distribution and endemism are essential in biogeography and biodiversity conservation. Here, we report three unrecorded species of foraminifera (Hemirotalia foraminulosa, Planispirillina denticulogranulata and Oolina brevisolenia) collected from Jeju Island and the South Sea (Korea). Planispirillina denticulogranulata is the second Planispirillina species recorded in Korea, which can be distinguished from congeners by its tubercles on the ventral side and grooves on the spiral suture. Hemirotalia foraminulosa is differentiated from the only congener H. calvifacta by multiple-scattered pits on the umbilicus, and it is the first report of Hemirotalia from Korean water. Oolina brevisolenia has specific bifurcating costae that characterize it from other congeners. This study contributes to documentation of the foraminiferal biodiversity in Korea, moreover, provides an essential basis for the expanded studies on modern foraminifera.

In this study, we briefly describe five newly recorded foraminiferal species from off the southern coast of Jeju Island: Ammolagena clavata, Neoeponides bradyi, Nodosaria lamnulifera, Rhabdammina abyssorum, and Uvigerina schwageri. Ammolagena clavata and Rhabdammina abyssorum are the first reports of the genera Ammolagena and Rhabdammina in Korea. In addition, R. abyssorum is reported from a depth of 103 m, which is a relatively shallow record within the distribution depth range for this agglutinated deep-sea species. Ammolagena clavata also shows interesting characteristics that the test usually attaches to substrates including shell fragments, sediment particles, or other foraminiferal tests. All other three species have typical calcareous and hyaline tests. The present report on unrecorded species improves the understanding of foraminiferal species diversity in Korean waters and confirms the need for the further research on foraminifera in the adjacent seas of Korea.
