Penicillium species have been actively studied in various fields, and many new and unrecorded species continue to be reported in Korea. Moreover, unidentified and misidentified Korean Penicillium species still exist in GenBank. Therefore, it is necessary to revise the Korean Penicillium inventory based on accurate identification. We collected Korean Penicillium nucleotide sequence records from GenBank using the newly developed software, GenMine, and re-identified Korean Penicillium based on the maximum likelihood trees. A total of 1681 Korean Penicillium GenBank nucleotide sequence records were collected from GenBank. In these records, 1208 strains with four major genes (Internal Transcribed Spacer rDNA region, b-tubulin, Calmodulin and RNA polymerase II) were selected for Penicillium reidentification. Among 1208 strains, 927 were identified, 82 were identified as other genera, the rest remained undetermined due to low phylogenetic resolution. Identified strains consisted of 206 Penicillium species, including 156 recorded species and 50 new species candidates. However, 37 species recorded in the national list of species in Korea were not found in GenBank. Further studies on the presence or absence of these species are required through literature investigation, additional sampling, and sequencing. Our study can be the basis for updating the Korean Penicillium inventory.

The goal of this study was to isolate wild yeasts from waters and soils in Sangjubo of Nakdong river and Daechung dam in Daejeon city, Korea and investigate characteristics of previously unrecorded novel wild yeasts. In total, 94 strains from 39 different species of wild yeasts were isolated from 47 soils and waters samples obtained from Sangjubo in Nakdong river. Among these, 3 strains, including Rhodosporidium azoricum JSL-GRU-009, represented novel yeast strains which were previous recorded. Two hundred nine strains from 105 different species of wild yeasts were isolated from 130 soils and water samples obtained from Daechungdaegyo and Daechung dam of Shintanjin in Daejeon city, Korea. Ten strains including Bullera pseudoalba JSL-GRU-005 also represented newly recorded strains in Korea. All the 13 previously unrecorded yeasts were oval or global in shape, and nine strains, including R. azoricum JSL-GRU-009, formed ascospores. Ten strains grew well in vitamin-free medium. R. azoricum JSL-GRU-009 grew well in 20% glucose-containing yeast extract-peptone-dextrose (YPD) medium and 3 strains, including Rhodotorula oryzicola JSL-GRU-003, grew well in 5% NaCl-containing YPD medium.

This is the second catalog listing unrecorded invertebrates discovered during the research project 'Discovery of Korean Indigenous Species'. The data to compile the catalog were primarily gathered from the final reports of the project, between 2013 and 2021. We present 38 previously undocumented species, belonging to four phyla (Platyhelminthes, Annelida, Rotifera and Arthropoda). Samples were collected from intertidal coastal waters, soil, freshwater ponds, reservoirs and hosts in South Korea. In this study, we provide brief taxonomic information, including collection site (GPS), diagnosis, specimen vouchers, figures of representative individuals and the Korean name newly assigned, for each species. All data were reviewed and updated by experts working on the respective taxonomic group. The aim of the present study is to publish species that have been previously reported through the project. Upon publication, these species will be added to the 'National Species List of Korea', curated by the National Institute of Biological Resources(NIBR).

A total of 22 bacterial strains belonging to the phylum Bacteroidetes were isolated primarily from aquatic environments such as seawater, freshwater, lagoon and tidal flat. One of these 22 strains was isolated from ginseng soil. Phylogenetic analyses based on 16S rRNA gene sequences revealed that 21 strains showed the high sequence similarities(${\geq}98.7%$) to the closest type strains and formed robust phylogenetic clades with closely related species in the phylum Bacteroidetes. One strain, which had been previously classified as Balneola vulgaris in the phylum Bacteroidetes, was identified as a member of the newly described phylum Rhodothermaeota. These strains had not been previously reported in Korea. Here, we report 21 species of 13 genera in the phylum Bacteroidetes and one species in the phylum Rhodothermaeota which were not reported in Korea. Morphological, biochemical, and physiological characteristics, isolation sources, and NIBR deposit numbers are described in the species descriptions.

In 2020, as a subset study to discover indigenous yeast species in Korea, a total of 22 yeast species were isolated from soil samples collected in Gwangju-si, Gyeonggi-do. Among them, 10 strains were unreported species. From the high 26S rRNA gene sequence similarity and formation of a robust phylogenetic clade with the closest species, it was determined that each strain belonged independent and predefined yeast species. The 22 strains were assigned to the genera Dothiora (1 strain), Sarocladium (1 strain), Tetrapisispora (1 strain) and Torulaspora (2 strains) of the phylum Ascomycota; the genera Erythrobasidium (1 strain), Leucosporidium (4 strains), Ustilentyloma (2 strains), Fellozyma (1 strain), Sampaiozyma (2 strains), Filobasidium (1 strain), Solicoccozyma (2 strains) and Vishniacozyma (4 strains) of the phylum Basidiomycota. This is the first official report of the following species in Korea: Dothiora cannabinae (1 strain), Sarocladium strictum (1 strain), Fellozyma inositophila (1 strain), Filobasidium magnum (1 strain), Solicoccozyma phenolicus (1 strain), Solicoccozyma terreus(1 strain), Vishniacozyma tephrensis(1 strain) and Vishniacozyma victoriae (3 strains). Cell morphology, phenotypic features and biochemical features are described in the Species Description section.

The taxonomic review of the family Trachipteridae was carried out based on the Trachipterus ishikawae (7 specimens), Zu cristatus (4 specimens), Desmodema polystictum (2 specimens) collected from the East Sea, South Sea and adjacent waters of Jeju Island of Korea from June 2006 to August 2008. Among them, D. polystictum was revealed as an unrecorded species from Korea, being characterized by the following characters: the ventral edge smooth; body color silvery white with a lot of large dark rounded spot. We proposed the new Korean name of the genus Desmodema as "Jeom-tu-ra-chi-sog", D. polystictum as "Jeom-tu-ra-chi". Z. cristatus has a elongated first six dorsal fin and pelvic fin rays. T. ishikawae has a row of sharp tubercles along the ventral edge, and straightly elongated body form. In meristic characters, the number of dorsal fin rays were 178~195 in T. ishikawae, 137~148 in Z. cristatus and 125~130 in D. polystictum, the number of vertebrae were well distinguished among three species; T. ishikawae (80~83), D. polystictum (72~74) and Z. cristatus (65~68).

Commelina benghalensis L. and Commelina diffusa Burm. f. belonging to Commelinaceae, two species previously unrecorded as Korean flora, were collected in the lowlands of Jeju Island in Korea. Commelina benghalensis of the two species is different from others of Commelinaceae in Korea by having funnelform spathes fused at the proximal margin of involucral bracts and cleistogamous flowers. In addition, Commelina diffusa differ from others by having a three-valve capsule and lanceolate and a base cordate or rounded spathelike involucral bracts. The somatic chromosome number of Commelina benghalensis was 2n = 2x = 22 and the sizes of chromosomes were very small, ranging from 1.25 to 2.70 ${\mu}m$. However, the Commelina diffusa chromosome number exceeded 2n = ca. 100, and a precise count could not be obtained. These species are known to be distributed in tropical and subtropical regions of Asia and Africa below the latitude of Jeju Island of Korea.
