As part of a comprehensive investigation of indigenous prokaryotic species in Republic of Korea in 2022, 156 bacterial strains were isolated from diverse environmental habitats. These strains were assigned to six phyla, namely Acidobacteriota, Deinococcota, Actinomycetota, Bacillota, Bacteroidota, and Pseudomonadota. Each strain was identified based on 16S rRNA gene sequence similarity (>98.7%) and the formation of robust phylogenetic clades with their closest reported species. Among isolates, there is one species belonging to the phylum Acidobacteriota, one species belonging to the phylum Deinococcota, 28 species belonging to the phylum Actinomycetota, 19 species belonging to the phylum Bacillota, 19 species belonging to the phylum Bacteroidota, and 88 species belonging to the phylum Pseudomonadota (comprising 34 species of the class Alphaproteobacteria, 20 species of the class Betaproteobacteria, and 34 species of the class Gammaproteobacteria). Based on 16S rRNA gene sequence analysis, each strain was assigned to independent and predefined bacterial species. Since there were no published or official reports regarding these 156 isolates in Republic of Korea, they are reported as unrecorded species in Republic of Korea. The Gram stain, colony and cell morphology, basic biochemical characteristic, isolation source, and strain ID of each species are described in the species descriptions.

In 2016, as part of a larger effort to discover indigenous prokaryotic species in Korea, we isolated the family Deinococcaceae and Planctomycetaceae as unrecorded bacterial species. From the high 16S rRNA gene sequence similarity (>98.5%) and formation of a robust phylogenetic clade with known species, it was determined that each strain was a distinct bacterial species. There are no official reports that these two species have been described in Korea; therefore, the bacterial strains of Deinococcus and Blastopirellula are described for the first time in Korea. Gram reaction, colony and cell morphology, basic biochemical characteristics, and isolation sources are also described in the species description section.

We surveyed moths on Gageodo island in the southwestern sea of the Korean Peninsula over three years (2009, 2012, 2013) and found a total of 253 species in 18 families. Geometridae had the greatest species richness, with 63 species, followed by Noctuidae, Erebidae, Crambidae and Sphingidae. The annual changes in species richness and abundance were not different and seasonal occurrence of species showed a unimodal pattern in which the numbers of species and individuals increased from April and May, peaked in June and decreased to September and October. Seven moth species (Pyralidae: Herculia drabicilialis Yamanaka, Didia striatella (Inoue); Crambidae: Clupeosoma pryeri (Butler), Demobotys pervulgalis (Hampson), Yezobotys dissimilis (Yamanaka), Syllepte cissalis Yamanaka; Erebidae: Hypena sinuosa (Wileman)) are reported for the first time in Korea.

Four unrecorded species (Barbella flagellifera, Isothecium hakkodense, Mnium orientale and Fissidens gardneri) and with one unrecorded genus, Barbella, are reported new to the Korean moss flora. B. flagellifera (Meteoriaceae) was found on a tree at alt. 300-350 m of parasitic Seogeomun-oreum Volcano on Jeju Island. The species are mainly distributed in subtropic regions. I. hakkodense (Lembophyllaceae) was found around the top of Seongin-bong on Ulleung Island. This species is similar to I. subdiversiforme, however, it can be distinguished by the morphologies of branch leaves and alar cells. M. orientale (Mniaceae) was collected from Mt. Jiri. This is similar to M. heterophyllum, however, it can be distinguished by plant size, number of teeth in leaf margin and cell size on leaf. F. gardneri (Fissidentaceae) was found along the valley of Mt. Palyeong, Jeollanam Province. This species is similar to F. obscurirete, but distinguished by the size of the plants and their leaves as well as the costal lengths of the leaves.

During the extensive survey of the prokaryotic species diversity in Korea, bacterial strains belonging to Betaproteobacteria and Epsilonproteobacteria were isolated from various sources including freshwater, sediment, soil and fish. A total of 23 isolates were obtained, among which 22 strains were assigned to the class Betaproteobacteria and one strain to the class Epsilonproteobacteria. The 22 betaproteobacterial strains were further assigned to Comamonadaceae (11 strains), Burkholderiaceae (6 strains), Oxalobacteraceae (2 strains), Neisseriaceae (1 strain) and unclassified family groups (2 strains). For the strains of Burkholderiaceae, 3 strains were identified as 3 species of Burkholderia, and 2 strains were as 2 species of Cupriavidus. For the strains of Comamonadaceae, 4 strains were identified as 2 species of the genus Hydrogenophaga, 2 strains as 2 species of Acidovorax, 2 strains as 2 species of Limnohabitans, and each of the remaining strains as single species of Comamonas, Curvibacter and Rhodoferax, respectively. For the strains of Oxalobacteraceae, 1 strain was identified as a species of Undibacterium, and the other strain as a species of Herbaspirillum. The strain belonging to Neisseriaceae was identified as a species of Iodobacter. The remaining strains of Betaproteobacteria were identified as species of Sphaerotilus and Methylibium respectively (family unassigned). The epsilonproteobacterial strain was identified as a species of Arcobacter of the family Camplyobacteraceae. The detailed description of each unrecorded species is provided.

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.

Testate amoebae are easily recognized as their characteristic shells from other protistan groups. They in which more than 1,900 species have been recorded are mixture of heterogeneous groups mainly composed of Amoebozoa and Cercozoa. In Korea, 74 species of testate amoebae have been recorded since late 1980s. Here I report a list of 12 unrecorded species of testate amoebae from Korea which were discovered during 2016-2018: Arcella crenulata Deflandre, 1928; Centropyxis cassis(Wallich, 1864); C. delicatula Penard, 1902; C. hirsuta Deflander, 1929; C. orbicularis Deflandre, 1929; C. sylvatica (Deflandre, 1929); Cyclopyxis eurystoma Deflandre, 1929; C. intermedia Kufferath, 1932; C. kahli(Deflandre, 1929); Difflugia diafana Vucetich, 1987; D. manicata Penard, 1902; Awerintzewia cyclostoma Schoutenden, 1906. As a result the fauna of testate amoebae in Korea is composed of 86 species. There are still much more species remained to be discovered in Korea. The faunal studies on testate amoebae will provide us valuable information about freshwater and soil environments.

The Mount Juwang was designated as a national park in 1976 because of its unique bedrock geology. Although Juwang National Park has maintained its natural ecosystem well, few macrofungal surveys have been carried out. As a part of a project supported by the National Institute of Biological Resources (NIBR) for the discovery of indigenous fungal species, we surveyed the mushrooms in Juwang National Park from 2018 to 2019. The macrofungi were identified based on morphological and molecular analyses. Among these fungi, five specimens were identified as species previously unrecorded in Korea: Calocybe decolorata, Crepidotus brunnescens, Mycena pearsoniana, Psathyrella phegophila, and P. sulcatotuberculosa. Three of these species are known to be rare in the world: Crepidotus brunnescens, P. phegophila, and P. sulcatotuberculosa. In this study, we provide detailed morphological descriptions of the five unrecorded species from Mt. Juwang in Korea.
