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).

During a comprehensive investigation of indigenous prokaryotic species in Korea, 25 and 10 bacterial strains assigned to the classes Alphaproteobacteria and Betaproteobacteria, respectively, were isolated from diverse environmental habitats, including soil, mud, tidal field, sea water, sand, rusted iron, and leaf. Based on their high 16S rRNA gene sequence similarities (>98.7%) and the formation of robust phylogenetic clades with type species, each strain was assigned to an independent and predefined bacterial species. Since there were no published or official reports regarding these 35 isolates in Korea, they - 25 species of 14 families in the 5 orders of Alphaproteobacteria and 10 species of 3 families in the two orders of Betaproteobacteria - have been reported as unrecorded species in Korea. In addition, Gram reaction, colony and cell morphology, basic biochemical characteristic, isolation source, and strain ID of each species are also described in the species description sections.

During a comprehensive investigation of indigenous prokaryotic species in Korea, 20 and one bacterial strains assigned to the phyla Bacillota and Verrucomicrobiota, respectively, were isolated from diverse environmental habitats, including soil, mud, tidal flat, seawater, sand, sediment, brackish water, and healthy human urine. Based on their high 16S rRNA gene sequence similarities (>98.7%) and the formation of robust phylogenetic clades with their closest related reported species, each strain was assigned to an independent and predefined bacterial species. Since there were no published or official reports regarding these 21 isolates in Korea, they - 20 species of four families in two orders of the phylum Bacillota and one species of the phylum Verrucomicrobiota - have been reported as unrecorded species in Korea. In addition, Gram staining, colony and cell morphology, basic biochemical characteristic, isolation source, and strain ID of each species are also described in the species description sections.

The phylum Bacteroidetes covers phenotypically diverse groups of Gram negative rods that do not form endospores, and currently includes 6 classes, 6 orders, 33 families and 380 genera. Members of Bacteroidetes can be aerobic and anaerobic heterotrophs, hydrogen utilizing chemolithotrophs, or methylotrophs. They can be isolated from diverse habitats including terrestrial and aquatic environments, environments with extreme physicochemical conditions, and animal and plant hosts. During a series of extensive surveys of prokaryotic species diversity in Korea, bacterial strains belonging to Bacteroidetes were isolated from various sources of aquatic and terrestrial environments. A total of 22 isolates were obtained, which represent 22 unrecorded species in Korea belonging to 14 genera of 6 families. Sixteen species among them were assigned to Flavobacteriaceae, two species were to Sphingobacteriaceae, and single species was to each of the families Bacteroidaceae, Balneolaceae, Chitinophagaceae and Cytophagaceae. At genus level, Chryseobacterium (5 species) and Flavobacterium (5 species) were the most abundant genera, and single species were obtained for the genera Bacteroides, Baloneola, Terrimonas, Dyadobacter, Aquimarina, Arenibacter, Gillisia, Gilvibacter, Salinimicrobium, Winogradskyella, Pedobacter and Sphingobacterium. The detailed descriptions of each unrecorded species are provided.

Our study aimed to discover indigenous prokaryotic species in Korea. A total of 29 bacterial species in the phylum Proteobacteria were isolated from freshwater and sediment of rivers and brackish zones in Korea. From the high 16S rRNA gene sequence similarity (${\geq}98.8%$) and formation of a robust phylogenetic clade with the closest species, it was determined that each strain belonged to an independent and predefined bacterial species. To our knowledge, there is no official report or publication that has previously described these 29 species in Korea. Specifically, we identified 10, 12, and seven species of eight, 12, and seven genera that belong to classes Alphaproteobacteria, Betaproteobacteria, and Gammaproteobacteria, respectively; all are reported as previously unrecorded bacterial species in Korea. The Gram reaction, colony and cell morphology, basic biochemical characteristics, isolation source, and strain IDs for each are also described.

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.
