Seven bacterial strains, 15J4M-1, 15J13-8, 16MFM10, 15J1-8, SR1-5-4, 15J13-6, and 15J8-11 assigned to the phylum Actinobacteria, Bacteroidetes, and Firmicutes were isolated from soil samples collected from Jeju, Korea. Phylogenetic analysis based on 16S rRNA gene sequence revealed that strains 15J4M-1, 15J13-8, 16MFM10, 15J1-8, SR1-5-4, 15J13-6, and 15J8-11 were most closely related to Bacillus selenatarsenatis $SF-1^T$ (with 99.4% similarity), Brevibacterium luteolum $CF87^T$ (99.5%), Carnobacterium iners CCUG $62000^T$ (99.6%), Exiguobacterium profundum $10C^T$ (99.3%), Larkinella insperata LMG $22510^T$ (99.3%), Pseudokineococcus lusitanus CECT $7306^T$ (99.4%), and Spirosoma endophyticum $EX36^T$ (99.3%), respectively. This is the first report of these seven species in Korea.

대구광역시에 위치한 금호강 강변에서 발견된 석죽과의 Silene antirrhina L.를 한반도 미기록종으로 확인하여 보고한다. 본 종은 속 내의 근연종인 끈끈이장구채(S. koreana Kom.) 및 끈끈이대나물(S. armeria L.)과 같이 선점이 있으나 개화시 수술이 꽃받침 밖으로 외출하지 않고, 종자의 표면이 유두상 돌기인 점에서 근연종과 뚜렷이 구분된다. 국명은 식물체가 소형이고 전체적으로 가는 점을 고려하여 '가는끈끈이장구채'로 명명하였으며, 생태사진과 주요 형질에 대한 기재 및 검색표를 제시하였다.

Trichogrammatidae 2종, Scelionidae 1종, Braconidae 5종, Ichneumonidae 7종 등 모두 15종이 발견되었다. 2. 이중 Apanteles chlonis와 Microgaster russata 등 2종은 한국미기록종임이 밝혀졌다. 3. Trichogramma chilonis, Eriborus terberans 그리고 Gambrus ruficoxatus 등의 3종은 문헌에만 기록되었을 뿐 본조사기간중 실제로 표본을 확인할 수 없었다.

Gnaphalium L. is a small herbaceous genus comprising up to 80 species in worldwide (Asia, North to South America, Africa, and Oceania). This genus is highly polymorphic which embrace uncommon broad morphological boundary, and thus further studies were needed to proper taxonomic delimitations for the genus and its relatives. Gnaphalium uliginosum L. was usually found in moist sites such as margins of lake, pond, reservoir, stream banks and paddy field. This squat plant is solely known species in Korean Gnaphalium. During the revisionary study of the tribe Gnaphalieae (Asteraceae) in Korea, however, we found several materials in domestic herbaria (e.g., SNU, KWNU) that identified as G. uliginosum or Gamochaeta pensylvanica (Willd.) Cabrera collected from central to northern Korea, but clearly differ to the morphology of G. uliginosum. The external morphology of the materials is seemingly the only feature at odds with G. uliginosum. However, its morphological characters such as tall erected stems (ca. 30cm), hairs on seeds and whitish tomentose hairs on the whole plants are easily distinguished from G. uliginosum, and rather it looks like G. tranzschelii Kirp. Although the name G. tranzschelii have been treated as synonym of G. uliginosum by several authors, its distinct morphology might be sufficient to separate to two independent taxa. Generally, the morphological polymorphisms and hybridization of G. uliginosum complicate the taxonomy of the species, and thus further investigation for their habitat, distribution and morphology were needed to their taxonomic entity.

Naturalization centers are hotspots where accidently introduced seeds first germinate and grow. Railways play important roles as corridors for movement, having positive effects on species dispersal and persistence, though they can also be invasion routes for undesirable plants. Geranium purpureum Vill., a new alien species in Korea, was found at the Bumil Railway Station, Busan, Gyeongsangnam-do, Korea. Most native Geranium species in Korea belong to the subgenus Geranium and section Geranium, but G. purpureum belongs to the subgenus Robertium and section Ruberta, with the "carpel-projection" method of seed dispersal. In other countries, G. purpureum is often compared with G. robertianum L., which is an ornamental plant in Korea. We assume that G. purpureum is a casual alien plant and that it is not likely to spread to other provinces, as it scarcely survives when the mean temperature in January is below $4^{\circ}C$. Moreover, it has not been found further north than Busan. We provide a key of allied taxa, information about the habitat, a description of the morphological characters, illustrations, and photographs.

In 2020, 11 Basidiomycetous yeast strains were isolated from soil samples collected from the forests of Namhansanseong in Korea. Among them, seven species were reported, but four species were unreported in Korea. To identify wild yeasts, pairwise sequence comparisons of D1/D2 domain of the 26S rRNA were performed using Basic Local Alignment Search Tool (BLAST). The cell morphologies and assimilation test are observed by phase contrast microscope and API 20C AUX kit, respectively. The 11 strains were assigned to the genera Rhodotorula (4 strains) of the order Sporidiobolales of the class Microbotryomycetes; and Cryptococcus(2 strains), Goffeauzyma (1 strains), Naganishia (2 strains) of the order Filobasidiales and Saitozyma (2 strains) of the order Tremellales of the class Tremellomycetes in the phylum Basidiomycota. The unreported yeast strains Cryptococcus gastricus 20n5-2, Goffeauzyma gilvescens 20n2-7, Naganishia adeliensis 20n8-1, and Naganishia friedmannii 20n24-1 belong to the family Filobasidiaceae. All strains had oval shaped cells and cream-colored colonies cultured on on YM agar for 3 days. In this study, we focus on the description of four unreported yeast species in Korea.

Two new records of marine nematodes, belonging to the family Ironidae de Man, 1876, are reported based on the specimens collected from intertidal sediments from the west coast of Korea. Conilia sinensis is characterized by a relatively long body length, a well-developed buccal cavity with three claw-like teeth, the presence of a single spicule with transverse striations, the presence of rib-shaped telamons, and single precloacal supplement. Pheronous donghaiensis is distinguished from other species of the genus by a well-developed buccal cavity with four claw-like solid teeth and minute denticles, relatively short and thick spicules with the central septum, the presence of 8-9 curved tubular-shaped precloacal supplements, and a sharp pointed tail with three small tubular supplements arranged into two rows in males. In this report, we provide a taxonomic description and illustrations of two unrecorded species of the family Ironidae by differential interference contrast microscopy. This is the first taxonomic report on the species of the family Ironidae from Korea.

Two known species of the family Comesomatidae Filipjev, 1918 were collected from marine sediments of the sublittoral zone in the East Sea, Korea and described and illustrated. Dorylaimopsis variabilis Muthumbi, Soetaert and Vincx, 1997, which was originally described from the Kenyan coast in the Indian Ocean, is recorded from the East Sea, Korea for the first time; there are only slight differences in amphidial fovea turns, body length, body width and relative length of tail. Setosabatieria hilarula (De Man, 1922), Platt, 1985, which was originally described from the North Sea, is recorded from the East Sea, Korea for the first time; there are only slight differences in the number of precloacal supplements, the relative length of tail and the posterior portion of tail. We provide pictorial keys for determination of valid species in the genera Dorylaimopsis Ditlevsen, 1918 and Setosabatieria Platt, 1985. This is the first description of the genus Dorylaimopsis and Setosabatieria from Korean waters.
