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.

This is a report on 40 species of the crabs which were collected during the period from July, 1958 to October , 1959 in the estern sea of Korea (East Sea) belonging to Kyungsang-pukto, apart of Kangwondo and Kyungsang -namdo. Among these, 17 915 genera, 8 families) are unrecorded species in the eastern sea and Platymaja wyville-thomsoni MIERS is an unrecorded species in Korea. Korea (Kuryongpo)seems to be the northern limit of the distribution of this species up to the present. 18 hitherto unreported species are added to the 39 known species, the total in the eastern sea being 57 species involved in 41 genera and 13 families, which show 44.5% of presently known 128 species of crabs in Korea.

As part of a larger study with the aim to discover indigenous prokaryotic species in Korea, nine bacterial strains were isolated and assigned to the phylum Proteobacteria in 2016. High 16S rRNA gene sequence similarity (>98.5%) and formation of a robust phylogenetic clades with known species indicated that each strain belongs to an independent and predefined bacterial species. This is the first report of these nine species in Korea: two strains of the Methylobacterium, two strains of the Microvirga, one strain of the Pantoea, and four strains of the Psychrobacter, all within the Proteobacteria. Gram reaction, colony and cell morphology, basic biochemical characteristics, and isolation sources are also described in the species description section.

In this paper, we present unrecorded protozoans of Korea that were discovered, through the 'Discovery of Korean Indigenous Species' project hosted by the 'National Institute of Biological Resources (NIBR)'. A taxonomic account is provided for each identified species, offering comprehensive information such as species name, Korean name, collection site, synonyms, specimen vouchers, diagnoses, and figures. This study introduces 13 previously unrecorded Korean protozoan species that are classified into three phyla: Amoebozoa, Cercozoa, and Ciliophora. Notably, the cercozoan family Chlamydophryidae was recorded in Korea for the first time, together with the discovery of three previously unreported genera: Diaphoropodon within Cercozoa, and Metauroleptus and Hemicycliostyla within Ciliophora.

During an investigation of unrecorded prokaryotic species in Korea, six unrecorded bacterial strains were isolated from soil samples collected from Uljin-gun. Based on a similarity search using the 16S rRNA gene sequence of the isolated strains and the construction of the neighbor-joining phylogenetic tree, five strains were identified to the genus Pseudomonas of the family Pseudomonadaceae, while one strain was identified as a species belonging to the genus Paenibacillus of the family Paenibacillaceae. The details of these unreported species, including gram staining reaction, colony and cell morphology, basic biochemical characteristics, strain ID, and isolation source, are described in the description of the strains.

청미래덩굴의 근권 토양을 온실에서 배양하여 Glomeromycota에 속하는 균류의 포자를 분리하였다. 분리된 포자는 18S partial rDNA 영역의 DNA 염기서열 분석과, 더 정확한 동정을 위해 추가적으로 ITS 영역과 28S rDNA 영역까지 포함하는 $Kr{\ddot{u}}ger$ fragment 지역의 염기서열을 분석하여 동정하였다. 동정 과정에서 2종의 국내 미기록종 Glomeromycota 균류의 포자를 확인하였으며, 확인된 종은 Diversispora eburnea, Paraglomus laccatum이다. 확인된 미기록종 포자의 형태적 특성 및 계통적 분석의 결과에 대해 기술하였다.

2018년 6월 1일부터 9월 17일까지 109일 동안, 총 112개 국외 발 국내 입항 선박을 대상으로 편승자 해충(hitchhiker insect pests)에 대한 모니터링을 실시하였다. 그 결과, 총 336개체의 편승자 해충을 확보하였으며, 이를 통합 분류학적 종동정 방법(integrative identification method)을 이용하여 9목 47과 159종으로 동정하였다. 이 중 총 3목 9과 14종의 한국 미분포종(not-distributed species)이 확인되어 보고하며, 검출된 미분포종에 대해서 침입종(invasive species) 내지 침입 가능종(invasive likelihood species)에 대한 위험성 평가를 위한 data sheet를 제공하였다. 또한, 미기록(unrecorded species), 미보고종(unreported species) 내지 신기록종(new recorded species)과 용어의 혼동을 피하기 위하여 본 연구에서는 미분포종(not-distributed species)을 제안하여 사용하였다.

During a survey of indigenous prokaryotic species diversity of the upstream Nakdong River, South Korea, 12 bacterial strains were isolated for further analysis. These bacterial strains were identified showing at least 98.7% 16S rRNA gene sequence similarity with known bacterial species that were previously unreported in South Korea. The 12 bacterial strains were phylogenetically diverse and assigned to four classes, eight orders, nine families, and ten different genera. The isolates were identified as Leucobacter holotrichiae (99.1%), Leucobacter tardus (99.9%), Rhodococcus rhodochrous (99.9%), Tessaracoccus oleiagri (100%), and Paeniglutamicibacter cryotolerans (99.3%), of the class Actinobacteria; Bacillus coagulans (99.7%) and Bacillus wudalianchiensis (99.1%) of the class Bacilli; Ochrobactrum pseudogrignonense (99.2%) and Paracoccus thiocyanatus (100%) of the class Alphaproteobacteria; and Ideonella azotifigens (99.0%), Polaromonas glacialis(99.3%), and Herbaspirillum seropedicae (99.5%) of the class Betaproteobacteria. The cellular and colonial morphology, biochemical properties, and phylogenetic position of these isolates were examined, and species descriptions are provided.

We, for the first time, reported molecular sequences of large subunit ribosomal DNA Dl-D3 region of A. hiranoi, A. leei and A. satoanum hitherto unreported. In addition, this study presented the full-length sequences of A. affine, A. fraterculus, A. catenella and A. tamarense occurring in Korean coastal waters. In total, 17 Alexandrium morphospecies were subjected to the phylogenetic analysis using the Maximum-likelihood (ML) method. The alignment result of sequences of A. hiranoi and A. pseudogonyaulax showed that there were only two substitutions without length heterogeneity implying their genetic affiliation. In ML tree, A. leei formed a deeply diverging branch probably because of the accelerated evolutionary rate, and its phylogenetic position was so ambiguous to resolve the phylogenetic relationship to the residual taxa. An A. satoanum culture showing morphological variation in the sulcal plate formed an independent divergent branch with consistent sister relationship to A. hiranoi/A. pseudogonyaulax clade supported by the high posterior probability (PP) value. Blast search in GenBank showed the sequence data of A. affine, A. fraterculus, A. catenella and A. tamarense corresponded to their morphological species designation. In ML tree, Alexandrium species were commonly split into four main clades. The inter-clade relationships were not clear and usually supported by the week PP values. In general, the sulcal plate of Alexandrium species seemed to reflect the true phylogeny at the main clade level, and the connection between the 1 and the apical pore complex seemed to reflect the phylogeny at the subclade level.
