  • We examined endophytic fungi from the needle leaves of three species of conifers in Korea: Abies nephrolepis, Thuja koraiensis, Pinus koraiensis. Endophytic fungi were isolated from the surface-sterilized leaves and identified based on morphological characteristics and Internal transcribed spacer sequences of rDNA. Three species of endophytic fungi isolated in this study were the first reported in Korea: Cryptosporiopsis actinidiae, Pestalotiopsis mangiferae, Pyrenochaeta cava.

  • We collected ciliates from terrestrial and aquatic habitats in Korea. Morphology was examined based on observations of both living and stained specimens. As a result of the observations, we found 24 previously unrecorded ciliate species to Korea. The morphology of these species are briefly described here: Tracheloraphis dracontoides, Condylostoma arenarium, Aspidisca steini, Australocirrus aspoecki, Sterkiella tricirrata, Stylonychia lemnae, Wallackia bujoreani, Bakuella marina, Anteholosticha sigmoidea, Holosticha pullaster, Urostyla grandis grandis, Chaenea vorax, Enchelys gasterosteus, Phialina salinarum, Mesodinium pulex, Aegyria oliva, Bryometopus pseudochilodon, Pinacocoleps tesselatus, Urozona buetschlii, Colpidium colpoda, Campanella umbellaria, Pseudovorticella difficilis, Zoothamnium parahiketes and Z. plumula. Among these 24 ciliates, S. tricirrata and U. grandis grandis were studied based on both the morphology and the morphogenesis.

A New Record of the Genus Stenomacrus (Hymenoptera: Ichneumonidae: Orthocentrinae) from South Korea (한국산 얼굴긴뺨자루맵시벌속(벌목: 맵시벌과: 긴뺨자루맵시벌아과)의 미기록종 보고)

  • Stenomacrus deletus (Thomson, 1897), belonging to Orthocentrinae of Ichneumonidae, is newly recognized in South Korea. Most Stenomacrus species are known as koinobiont endoparasitoids of dipteran, lepidopteran, and coleopteran hosts. In this study, an additional species is recorded for the first time from South Korea. Diagnoses of genus and an unrecorded species, as well as illustrations of this species are provided.

  • While conducting a floristic study of Korean moss, we discovered one unrecorded species collected from Mt. Hallasan in Korea. Brachydontium olympicum (E. Britton) T. T. McIntosh & J. R. Spence is recorded for the first time for Korea. Unlike other species of Brachydontium, this species has no peristome and its distal laminal cells are mostly isodiametric.

  • A total of 118 fungal specimens were collected from Mt. Manggyeong, Chungnam province, Korea between July and October 2014. All specimens were identified to the species level using a combination of morphological characteristics and DNA sequencing. Out of 118 specimens, eight species, Amanita manginiana, A. pilosella, Calvatia holothurioides, Cantharellus tabernensis, Dicephalospora rufocornea, Gymnopus menehune, Marasmius brunneospermus, and Russula cerolens, have not been previously reported in Korea.

  • This research was conducted to find the indigenous diatom species unrecorded in Korea from February to December 2016. The samples were taken at 28 sites of the coastal regions on the west coast of Korea and Jeju Island. Diatoms were collected mostly from sand and mud of tidal flats, including gravel, seaweed on the bottom and macrophytes floating in the seawater. Diatom specimens were observed by means of light and scanning electron microscopy. Twenty one species were discovered and added as new specimens to the Korean diatom flora, which are divided into 9 orders, 12 families, and 16 genera. The list and photographs of the species are included with the description of the morphological characteristics and distribution in Korea.

  • Unarmored dinoflagellates, in the family Kareniaceae, include harmful or toxic bloom-forming species, which are associated with massive fish kills and mortalities of marine organisms worldwide. The occurrence and distribution of the toxigenic species in the family Kareniaceae were investigated in the brackish and coastal waters of Korea between July 2018 and October 2020. During the survey, we collected seven newly recorded species; Karenia papilionacea, Karlodinium digitatum, Karl. veneficum, Karl. zhouanum, Takayama acrotrocha, T. helix, and T. tasmanica. A total of fifteen strains of the seven taxa were successfully established as clonal cultures and examined using LM, SEM, and molecular phylogeny inferred from LSU rDNA sequences. Herein, we present the taxonomic information, morphological features, and molecular phylogenetic positions of the unrecorded dinoflagellate species collected from Korean coastal waters.

  • The family Araneidae is a group of orb-weaving spiders and is one of the most diverse groups among the order Araneae. Eighty-one species belonging to 25 genera have been recorded in Korea to date. In this study, four araneid spiders in three genera, viz., Araneus mayumiae, Araneus ogatai, Cyclosa onoi, and Plebs baotianmanensis, were discovered for the first time in Korea. Additionally, Plebs yebongsanensis is removed from synonymy of Plebs sachalinensis, and treated as a new junior synonym of P. baotianmanensis, based on a morphological comparison of females of three Plebs species. Detailed descriptions of four species are provided with accompanying photographs.

  • A taxonomic study was carried out to discover unrecorded species of South Korean Exetastes of which six taxa were previously known. In the present study, another six taxa were newly recognized from the country: E. adpressorius, E. allopus, E. fukuchiyamanus, E. illyricus, E. sapponensis and E. tomentosus. With the result of this study, 11 species and one subspecies in Exetastes are in total known from South Korea. In addition, a key to the South Korean species and the diagnoses and digital images of the six newly recorded species are provided.
