A total of 36 species and 11 genera of the fly family Lauxanidae have been previously recorded in Korean Peninsula. As a result of our ongoing study of this family, we here report the following nine species new to Korea: Homoneura albomarginata Czerny, 1932, Minettia filia (Becker), 1895, Pachycerina alutacea Shatalkin, 1998, Poecilolycia zherichini Shatalkin, 2000, Protrigonometopus sexlituris (Shatalkin), 1992, Salebrifacies czurkini Shatalkin, 1992, Sapromyza albiceps Fallén, 1820, Steganopsis dichroa Shatalkin, 1998, and Trigonometopus eborifacies Shatalkin, 1997. The genera Poecilolycia Shewell, 1986, Salebrifacies Shatalkin, 1992, and Steganopsis de Meijere, 1910 are recognized for the first time in this country. Therefore, 45 species in 14 genera are now officially recognized for the Korean lauxaniid fauna. In addition, we provide diagnoses and color photographs of adult external structures including male genitalia to aid their specific identification.

The leucosiid crabs are common species on soft sediment from the intertidal flat to shelf and slope depths. The genus Nursia Leach, 1817 is characterized by the pentagonal shape of the carapace and the presence of the buccal cavern on the pterygostomian region. As a result of the systematic study on the Korean brachyuran species, Nursia rhomboidalis (Miers, 1879) is newly recorded in Korean fauna. Korean Leucosiidae is now composed of 14 species belonging to eight genera. The description and illustrations of this species are provided.

We report 14 species of flowering plants as new additions to the flora of Laos. These are Illex viridis (Aquifoliaceae), Capparis erycibe (Capparaceae), Euphorbia bokorensis (Euphorbiaceae), Exacum darae (Gentianaceae), Aeschynanthus cambodiensis (Gesneriaceae), Tetraphyllum roseum (Gesneriaceae), Utricularia gibba (Lentibulariaceae), Macrosolen brandisianus (Loranthaceae), Decaschistia siamensis (Malvaceae), Nyssa yunnanensis (Nyssaceae), Adenia penangiana var. penangiana (Passifloraceae), Pentaphylax euryoides (Pentaphylacaceae), Wikstroemia bokorensis (Thymelaeaceae), and Debregeasia wallichiana (Urticaceae). We discovered the species during a botanical survey of the Phou Khao Khouay National Biodiversity Conservation Area (PKKNBCA) of Lao PDR in 2015-2019. In addition, nine rarely collected flowering plant species in Laos are newly reported for the PKKNBCA.

A green alga specimen was collected from the eastern coast of Korea. This species shared the typical features of genus Ulva and was characterized by irregularly shaped thalli, relatively small and thick thallus, entire undulate margins without serrations, and one or two pyrenoids per cell. In a phylogenetic tree, based on sequences of the nuclear-encoded internal transcribed spacer region, it nests as a sister clade to a few species including Ulva ohnoi, which has a relatively large thallus. This Korean algal specimen differs from the species forming the same subclades, including U. ohnoi, Ulva fasciata, Ulva reticulata, and Ulva gigantean, and has a relatively small (3-8 cm) and thick (60-100 ㎛) thallus. Of these species, U. ohnoi, originally described from Japan, is similar to the Korean alga as it had a thick thallus of 30-90 ㎛, but it has microscopic serrations on the thallus margin, unlike the Korean alga. The genetic distance between the Korean alga species and the aforementioned species was determined to be 1.8%-4.8%, indicating an inter-specific divergence level at the genus Ulva. Herein, Ulva grossa sp. nov. (Ulvales, Chlorophyta) from Korea is described based on the morphological and molecular analyses.

A study of freshwater ichthyofauna was conducted in order to clarify its significance at 14 upstream sites in Muju, Jangsu, Geochang and Hamyang districts in Deogyusan National Park, enclosing Baekdudaegan. The freshwater fish fauna of the Park was measured at the 14 sampling locations from May 2003 to September 2003. The fifteen species gauged included four Korean endemic species and or subspecies (Squalidus japonicus coreanus, Iksookimia longicorpa, Coreoperca herzi, Odontobutis platycephala). Fourteen species were found in the Keum River and seven species in the Nakdong River. However, common species were Punchocypris, Rhynchocypris oxycephalus, Zacco temmincki, Misgurnus anguillicaudatus, Coreoperca herzi, and Odontobutis pzatycephala. The dominant species of these regions were Zacco temmincki and Rhynchocypris oxycephalus. Past studies conducted in Baekdudaegan mostly concernedflora and vegetation. In the future, new study concepts for stream corridors involving both animal and plant should be introduced.

Most known species in the Physalacriaceae are saprotrophs that grow on decaying leaves and wood, and approximately 21 genera in the Physalacriaceae have been reported worldwide. During an ongoing survey of indigenous fungi in Korea, four specimens belonging to the Physalacriaceae were collected on Ulleung Island. These specimens were identified as three species based on morphological characteristics and molecular analysis of rDNA-internal transcribed spacer sequences. Three species in three genera were shown to be new records in Korea: Hymenopellis orientalis, Paraxerula hongoi, and Ponticulomyces orientalis. The latter two are the first records of these genera in Korea. In this study, we provide detailed morphological descriptions of these species and describe their phylogenetic position within the Physalacriaceae.

The genus Neosiphonia Kim and Lee 1999 contains approximately 30 species worldwide. Unidentified samples from Peru are here described as a new species, Neosiphonia ramirezii sp. nov., on the basis of morphological and molecular data. N. ramirezii sp. nov. is characterized by the presence of a limited prostrate system, well-developed erect filaments, rhizoids cut off from pericentral cells by cross walls, four pericentral cells that are completely ecorticate, scarce trichoblasts, inconspicuous scar cells, procarps with three-celled carpogonial branches, spermatangial branches developed from basal cells of forked trichoblasts, and spirally arranged tetrasporangia. Our new species is distinct from N. flaccidissima (Hollenberg) Kim et Lee, N. sphaerocarpa (Borgesen) Kim et Lee, and N. savatieri (Hariot) Kim et Lee from the Pacific temperate coast of South America and from 14 Neosiphonia species reported worldwide by having limited prostrate filaments attached by numerous rhizoids, dichotomous ("Y" shaped) branches in the main axes, and scarce trichoblasts. Phylogenetic rbcL analyses confirm the placement of the new taxon as a distinct species in the genus Neosiphonia.

Three anomuran species (Crustacea, Decapoda), Pagurus cavimanus(Miers), P. gracilipes(Stimpson) and P. anomalus(Balss) were collected from the coastal seas of Gangweon-do (Province) and Jeourabug-do (Province) in May, 1969 and August, 1970 and described as the additional species to the fauna of Korea.

We report two species of Eupithecia for the first time from Korea. Two females of Eupithecia sophia Butler were collected from Jejudo Island and Sobaeksan Mt., Danyang, and two males of Eupithecia niphonaria Inoue were collected from Duryunsan Mt., Haenam. Up to now, a total of 51 species of Eupithecia are recorded from Korea. Diagnosis and description of each species are given with the figures of genitalia.

New square planar nickel(Ⅱ) complexes with various 1-alkyl (4a-4c) and 1-hydroxyalkyl (4d-4f) derivatives of the 14-membered pentaaza macrocycle 8-ethyl-8-nitro-1,3,6,10,13-pentaazacyclotetradecane have been synthesized by two-step metal template condensation reactions of ethylenediamine, nitroethane, formaldehyde, and appropriate primary amines. The nitro group and/or hydroxyl group of 4a-4f are not directly involved in the coordination. The nickel(Ⅱ) complexes exist in coordinating solvents such as MeCN, Me2SO, and H2O as equilibrium mixtures of the square planar [Ni(L)]2+(L=4a-4f) and octahedral species [Ni(L)S2]2+(S=solvent molecule). Although the ligand field strength and redox potentials of the complexes are not affected by the nature of the substituents, the formation of octahedral species for 4d-4f in MeCN is strongly restricted by the hydroxyl group. Synthesis, characterization, and solution behaviors of the nickel(Ⅱ) complexes are described.
