  • In order to identify an unknown wood sample native to Korea. the softwood databases(KSWCHUN; Korean SoftWood CHUN) and the hardwood databases(KHWCHUN; Korean HardWood CHUN) had been built. and the new computer searching programs(IDINEX; IDentification INformation EXpress) has been written in Turbo Pascal(V.5.0) and in Macro Assembly(V.5.0). The characters of the data were based on the 74 features of softwood and on the 148 features of hardwood which are a part of new "IAWA list of microscopic features for hardwood identification" published in 1989. For the purpose of this investigation the wood anatomical nature of 25 species of softwood(13 genera of 5 families) and of 112 species of hardwood(57 genera of 31 families) were observed under a scanning electron microscope and light microscope. and a lot of literature used. The IDINEX programs are based on edge-punched card keys. with several improvements. The maximum number of features in the IDINEX is 229. but that is fixed for a given database. Large numbers of taxa are handled efficiently and new taxa easily added. A search may be based on sequence numbers of features. Comparisons are made sequentially by feature and taxon using the entire suite of features specified to produce the list of possible matching taxa. The results are followings. (1) The databases of Korean wood and the searching programs(IDINEX) had been built. (2) The databases of Korean wood could be an information to search an unknown wood. (3) The databases would be valuable. for the new features, which were not mentioned in Korean wood up to the present. were observed in details. (4) The ultrastructures of the cell walls(warty layer) and crystals observed under a scanning electron microscope will be helpful to search an unknown wood in particular. (5) The searching process is more quick and accurate than the others. 6) We can obtain the information on the differences of a species from the other and search an unknown wood using probability. in IDINEX, (7) The IDINEX will be utilized to identify and classify an animal life, vegetable world, mineral kingdom, and so on.

  • Moniligastrids are an important yet often ignored earthworm group commonly found in cultivated soils, especially paddy, in the tropical East. Seven new taxa are: Drawida koreana austri, D. koreana nanjiro, D. koreana shindo, D. odaesan, D. jeombongsan, D. companio and D. csuzdii Blakemore spp. or sub-spp. nov. from Korea. Drawida csuzdii is the first new species from North Korea since Lumbricidae Eisenia koreana (Zicsi, 1972). Historical East Asian moniligastrids are reviewed chronologically and Drawida barwelli (Beddard, 1886), D. japonica (Michaelsen, 1892) and D. siemsseni Michaelsen, 1910 are compared on their museum types. These three taxa were thought similar and related to D. nepalensis Michaelsen, 1907 and its possible synonym D. burchardi Michaelsen, 1903 (priority!) and both of these to prior D. uniqua (Bourne, 1887). Indian Drawida calebi Gates, 1945 is compared to new material of D. japonica from Japan, and D. willsi Michaelsen, 1907 to the new sub-species of D. koreana Kobayashi, 1938 from Korea. Where available, mtDNA COI gene barcodes are provided to help objective determinations and a phylogram is provided with outgroup Ocnerodrilidae Eukerria saltensis (Beddard, 1895) itself found in rice paddy/irrigation. The challenge now is comparison of all early taxa in their various homelands in order to assess the genetic variability and taxonomic boundaries acceptable, especially for unpigmented D. barwelli and also for pink/grey D. japonica and blue/grey D. koreana. A checklist of moniligastrids is appended showing 22 species from China (including Hainan and Taiwan), 21 from Korea, nine from Japan and the Drawida ghilarovi Gates, 1969 species-complex from far eastern Russian (Siberia). Recent Drawida dandongensis Zhang & Sun, 2014 from Sino-Korean border is misdescribed and cannot be meaningfully compared to any other Drawidas.

  • An earthworm survey of Busan metropolitan area unearthed a dozen taxa in four families (including Enchytraeidae). Members of mostly common, cosmopolitan earthworm species-complexes were: Drawida cf. koreana Kobayashi, 1938, Amynthas cf. corticis (Kinberg, 1867), Aporrectodea trapezoides (Dug$\grave{e}$s, 1828) and Eisenia fetida (Savigny, 1826). Also found were Amynthas hupeiensis (Michaelsen, 1895), A. masatakae (Beddard, 1892) and Metaphire ryunome Blakemore, 2012 - the latter a new Korean record. New taxa are: moniligastrid Drawida songae yeongdo subsp. n.; megascolecid Amynthas carnosus roki subsp. n. which is compared to nominal taxon A. carnosus (Goto and Hatai, 1899) from Japan, to A. carnosus monstriferus (Kobayashi, 1936) stat. n. from Korea and to A. lichuanensis Wang and Qiu, 2005 stat. n. from China; plus lumbricid Eisenia japonica vaga subsp. n. deemed an objectively-based molecular taxon on its unique DNA COI gene barcode. Restoration of Eisenia xanthurus (Templeton, 1836) for E. andrei is mooted (in Appendix).

  • A total of 34 taxa, 33 species and one variety, are newly added to the moss checklist of Korea. They were collected on Jejudo Island, Samcheok limestone areas in Gangwon Province, and Socheongdo Island from 2015 to 2018 and organized into 19 families and 26 genera. Additionally, eight genera are new to Korea. This study verifies the distributions of nine species whose distributions and specimens have remained unknown thus far. Finally, two unrecorded taxa, consisting of one species and one variety, are identified by reexamining Korean specimens deposited at the National Museum and Science in Japan (TNS). The specimens were collected in 1942 and 1940 from Mt. Baekdusan and Anbyun in North Korea.

  • We report a new distribution of Carex foraminata C. B. Clarke on the Korean Peninsula. This species was first reported in China and is distributed in Jiangxi and Zhejiang Provinces. We found this species on Hongdo Island in Heuksan-myeon, Shinan-gun, Jeollanam-do in Korea. Carex foraminata is similar to the related taxa C. brevispicula G. H. Nam & G. Y. Chung, C. chungii Z. P. Wang, and C. genkaiensis Ohwi in that its achenes are constricted in the middle part. However, C. foraminata is distinguished from C. brevispicula and C. chungii by its pistillate scale apexes, which are acute or shortly awned and by its achene apexes, which are shortly cylindrical; C. foraminata is distinguished from C. genkaiensis by its pistillate scale and achene shape. A precise description, illustration, photographs, and a key to related taxa are provided.

  • The International Committee for Taxonomy of Viruses (ICTV), which was formed over 30 years ago, aims to develop a single, universal taxonomic scheme for all viruses or, in other words, "the classification of viruses and the assignment of names to taxa". Plant Virus taxonomy is in charge of Plant Virus Subcommittee, a substructure of the ICTV. The ICTV has been most successfully pursuing that aim and its mammoth 'Seventh Report' records details of the names it has collated and approved, and of the classification, it has devised. The current 7th ICTV report published in 2000 contains plant viruses of 951 species in 79 genera in 17 families, though 24 of the 79 genera are floating genera, that is, they are not included in any established families. Proposed name of new or existing viruses are vote for the accepted taxonomic proposals by ICTV Executive Committee meeting. The approved results have been published as the ICTV reports providing standard names and taxa of viruses all over the world. A number of new plant viruses have been identified or reclassified in the genus or species level, and new genera and families have been proposed.(중략)
