  • Haraldiophyllum hawaiiense sp. nov. is described as a new mesophotic alga and a new genus record for the Hawaiian Islands. Six specimens were collected at a depth range of 81-93 m from Papahānaumokuākea Marine National Monument, and their morphology investigated, as well as molecular phylogenetic analyses of the plastidial ribulose-1,5-bisphosphate carboxylase-oxygenase large-subunit (rbcL) gene and a concatenated alignment of rbcL and nuclear large-subunit rRNA gene (LSU) sequences. Phylogenetic analyses supported H. hawaiiense sp. nov. as a distinct lineage within the genus Haraldiophyllum, and sister to a large clade containing the type species, H. bonnemaisonii, as well as H. crispatum and an undescribed European specimen. The six Hawaiian specimens were shown to be identical, but unique among other species of the genus as well as the recently segregated genus Neoharaldiophyllum, which comprises half of the species previously included in Haraldiophyllum. The vegetative morphology of H. hawaiiense sp. nov. resembles Neoharaldiophyllum udoense (formerly H. udoensis); however, no female or post-fertilization structures were found in the Hawaiian specimens to allow a more comprehensive comparison. The molecular phylogenies demonstrate that Haraldiophyllum is paraphyletic, suggesting either that the Myriogrammeae tribe includes undescribed genera, including Haraldiophyllum sensu stricto, or that Neoharaldiophyllum species should be transferred into the genus Haraldiophyllum. However, based on vegetative morphology and molecular analyses, and pending resolution of this taxonomic issue, the Hawaiian specimens are placed within the genus Haraldiophyllum. This new record for the Hawaiian Islands highlights the novel biodiversity from mesophotic depths, reaffirming the need for further investigation into the biodiversity of Mesophotic Coral Ecosystems.

  • A research probing for the unrecorded and taxonomically undescribed indigenous species has been initiated since 2006. Samples were collected from an intertidal zone along the coasts of Korea as well as around the Jeju Island. We have found five unrecorded species of four genera belonging to the order Dinophysiales, Gymnodiniales, Peridiniales, and Prorocentrales. The species are as follows, Sinophysis canaliculata (2017) Bispidodinium angelaceum (2015), Cabra armorica (2016), Prorocentrum bimaculatum (2017), and P. tsawwassenense (2017) (note; The numbers in parenthesis refer to the year in which the species was reported as unrecorded indigenous species by National Institute of Biological Resources, NIBR hereafter).

  • Four strains of Penicillium and Talaromyces species are described and illustrated in an inventory of fungal species belonging to Eurotiales. The strains, CNUFC-DDS17-1, CNUFC-DDS27-1, CNUFC-PTM72-1, and CNUFC-YJW3-31, were isolated from soil and freshwater samples from South Korea. Based on their morphological characteristics and sequence analyses by the combined b-tubulin and calmodulin gene, the CNUFC-DDS17-1, CNUFC-DDS27-1, CNUFC-PTM72-1, and CNUFC-YJW3-31 isolates were identified as Penicillium pasqualense, Penicillium sanguifluum, Talaromyces apiculatus, and Talaromyces liani, respectively. The designated strains were found to represent a previously undescribed species of Korean fungal biota. In this study, detailed morphological descriptions and phylogenetic relationships of these species are provided.

  • Dictyostelid cellular slime molds isolated quantitatibly from the oils of evergreen broad-leaved forest and moist grassland of mt. halla in korea. nineteen species were found, including four undescribed species. species underscribed in korea are dictyostelium aureum var. aureum, d. crassicaule, d. monochasioides, and polysphondylium tenuissimum. Among these isolates, d. crassicaule and d. monochasioides were found only in evergreen broad-leaved forest, and p.tenuissimum was commonly found in moist grassland and meadow. in warn temperate regions investigated, d. mucoroides occurred rarely. It was noticeadle that d. sphaerocephalum, d. aureum var. aureum and d. purpureum were much more commonly found in warm temperate region. Species diversity in evergreen broad-leaved forest was the highest among the forests investigated until now in korea. Many isolates in mt. halla distributed differently in relation to the vegetations and altitudes. distritution patterns of isolates from mt. halla were discussed.

  • The most recent, Jeong and Nakabo (1997) described Raja koreana as a new species based on an adult female specimen collected from the southwestern coast of Korean Peninsula. Raja koreana has several unique characters not shared with any other supraspecific taxa of Rajoidei, but it was provisionally included in the genus Raja because of having no information of its clasper. Later, two mature males and a few specimens of the species were collected from near the type locality. Therefore, a new genus should be erected for this species. The new genus is characterized by the followings: Rostral shaft straight, narrow and thick in depth: unsegmented base with filamentous cartilage. Dorsal surface of tail with a row of distinct thorns along midline, patches of distinct thorns anterior to first dorsal fin and between first and second dorsal fins in bathe sexes; most thorns directed anteriorly, and thornlets directed posteriorly. Scapulocoracoid comparatively short and high, rear corner high, without anterior bridge, postventral fenestra expanded. Distal tip of accessory terminal 1 claspser cartilage well separated from the tip of accessory terminal 2 clasper cartilage.
