Ostrea denselamellosa and Eriocheir japonica samples were collected from the Seomjin River in 2019 as part of the "Research of Host-Associated Bacteria" research program. Almost 200 bacterial strains were isolated from the O. denselamellosa and E. japonica samples and subsequently identified by 16S rRNA gene sequencing. Among the bacterial isolates, ten strains possessed greater than 98.7% sequence similarity with published bacterial species that had not previously been recorded in Korea. These species were phylogenetically diverse, belonging to three phyla, four classes, seven orders, and eight genera. At the genus and class level, the previously unrecorded species belonged to Pseudoalteromonas, Aliivibrio, Rheinheimera, Leucothrix, and Shewanella of the class Gamma-proteobacteria, Olleya of the class Flavobacteriia, Algoriphagus of the class Cytophagia, and Lactococcus of the class Bacilli. The previously unrecorded species were further characterized by examining their Gram staining, colony and cell morphology, biochemical properties, and phylogenetic positions.

To obtain unrecorded bacterial species from Korean islands, various samples were collected from the islands in 2022. After plating the samples on marine agar or Reasoner's 2A, and incubating aerobically, approximately 1,200 bacterial strains were isolated and identified using 16S rRNA gene sequences. A total of 10 strains showed ≥98.7% 16S rRNA gene sequence similarity with the bacterial species that were validly published but not reported in Korea. The unrecorded bacterial strains belong to three phyla, five classes, 10 orders, 10 families, and 10 genera, which are assigned to Sphingomonas, Falsirhodobacter and Asticcacaulis of the class Alphaproteobacteria; Colwellia and Halomonas of the class Gammaproteobacteria; Chitinophaga of the class Chitinophagia; Chryseobacterium of the class Flavobacteriia; Microlunatus, Zhihengliuella, and Streptomyces of the class Actinomycetia. The details of the unreported species including Gram reaction, colony and cell morphology, biochemical characteristics, and phylogenetic position are also provided in the description of the strains.

Five unrecorded species (Oedipodium griffithianum, Myurella tenerrima, Trachypus bicolor, Coscinodon humilis, Meteorium miquelianum subsp. atrovariegatum) with one unrecorded family and two unrecorded genera, were reported as new to the Korean moss flora. The monotypic family Oedipodiaceae consisting of a single genus and single species was distinguished from Splachnaceae by small plants that were 10 mm in length simple or sometimes branched, obovate-spathulate to ${\pm}$ orbicular, costa ending below the apex and entire margins except for the lower long-ciliate portion The species was first found at the top of the Mt. Seorak at an altitude of 1708 m. The two genera, Myurella and Coscinodon were found in the Korean Peninsula. Myurella tenerrima (Theliaceae) was found around the top of Jung-bong on Mt. Jiri. It was mixed with other mosses in the crevices of rocks in the alpine regions. The species is similar to M. sibirica, yet it can be distinguished by the position of papilla in the median laminal cells. Coscinodon humilis (Grimmiaceae) were found on the ridge of Mt. Gaya. C. humilis has a variety of hyaline apex according to leaf position and forms a capsule so it can be distinguished by family. Trachypus bicolor and Meteorium miquelianum subsp. atrovariegatum are unrecorded species. T. bicolor (Trachypodaceae) were found on the ridge of Mt. Gaya. T. bicolor is similar to T. humilis but distinguished by the costal lengths of the leaves. M. miquelianum subsp. atrovariegatum (Meteoriaceae) was found in Gageo-do. This species was distinguished by the plant form and morphology of stem leaves in the same genus.

Here, we have described and illustrated a new endemic species of Scutellaria orthocalyx. This species, from Jeju-do, Korea, is clearly distinguished from other species of Scutellaria orthocalyx, especially its close relative, Scutellaria orthocalyx has relatively many leaves further down the stem. The shape of leaves begins linear and becomes lanceolate. Scutellaria orthocalyx can also have long shaped leaves on the upper part. Scutellaria baicalensis by linear, terete, fistulous and long leaves. A index to these species is provided.

Fungi act as important decomposers in the forest environment. They recycle essential nutrients, promote plant growth through mycorrhizal relationships, and act as food for small animals. Samples of 265 indigenous fungal species were collected from Mudeungsan National Park in 2020. These species were identified based on morphological, molecular, and phylogenetic analyses using the internal transcribed spacer (ITS), nuclear large subunit rRNA (LSU), and RNA polymerase II second largest subunit (rpb2) regions. Subsequently, seven species were identified as unrecorded species in Korea: Cordyceps cicadae, Dentocorticium bicolor, Hymenochaete nanospora, Physisporinus crataegi, Rigidoporus piceicola, Russula raoultii, and Scutellinia crinita. This study reveals their detailed macro- and microscopic morphological characteristics with phylogenetic trees to report them as unrecorded species in Korea.

One unrecorded species of Suaeda is found from the western and southern coast of Korea. The morphological characteristics and habitat of the plant are described. The species is distinguished from the other Korean species in the genus by its thin and broad leaves and the stellate shape of fruits.

We report an unrecorded species of Viburnum, V. japonicum (Thunb.) Sprengel, found in Gageo-do Island, a subtropical zone in Jeollanam-do Province. We named a species Foo-reun-ga-mak-sal. It is easily distinguishable from other recorded species of Viburnum by the characteristics such as exposed winter buds and indeciduous leaves with lustrous and glabrous texture.

A research probing for the unrecorded and taxonomically undescribed indigenous species has been initiated since 2006. Samples were collected from an intertidal zone along the coasts of Korea as well as around the Jeju Island. We have found five unrecorded species of four genera belonging to the order Dinophysiales, Gymnodiniales, Peridiniales, and Prorocentrales. The species are as follows, Sinophysis canaliculata (2017) Bispidodinium angelaceum (2015), Cabra armorica (2016), Prorocentrum bimaculatum (2017), and P. tsawwassenense (2017) (note; The numbers in parenthesis refer to the year in which the species was reported as unrecorded indigenous species by National Institute of Biological Resources, NIBR hereafter).

Through the 'Discovery of Korean Indigenous Species' project hosted by the National Institute of Biological Resources (NIBR), new or unrecorded species of various protozoans inhabiting the Korean Peninsula have been discovered. Samples were collected from marine, freshwater, and soil habitats in South Korea and all species were identified and reviewed by experts working on the respective taxonomic group. This study includes 17 unrecorded Korean protozoan species discovered through this project, which belong to four phyla: Amoebozoa Lühe, 1913, Cercozoa Cavalier-Smith, 1998, Euglenozoa Cavalier-Smith, 1981, and Ciliophora Doflein, 1901. Among them, three families (Rhogostomidae Dumack et al., 2017, Parauronematidae Small and Lynn, 1985, and Cyclidiidae Ehrenberg, 1838) and three genera (Rhogostoma Belar, 1921, Parauronema Thompson, 1967, and Cyclidium Müller, 1773) were reported for the first time in Korea. Unlike the previous paper of 2017, this study provides a comprehensive taxonomic account of each species (e.g., species name, collection site, synonyms, specimen vouchers, diagnoses, and figures). Additionally, all the species were assigned Korean names.

While collecting Poaceae weeds at Jeju-do, we found two unrecorded species of the Paspalum, P. notatum Fl$\ddot{u}$gg$\acute{e}$ and P. urvillei Steud. We provide the descriptions and illustrations of both species. Key to the newly recorded species and related taxa of Korean Paspalum is also presented.
