  • A new genus Goodingius is proposed to incorporate Hemicyclops adhaerens(Williams), H. arenicolae Gooding, H. elongatus Wilson and H. subadhaerens Gooding, all of which bear the six-segmented female urosome, three mandibular elements (or three elements plus one rudimentary setule), five setae on the first antennular segment, and no inner coxal seta of leg 4. The genus Giardella Canu, a sister taxon of Goodingius, is redefined as possessing eight elements on the third exopodal segment of leg 3, only a single inner seta on the second endopodal segment of leg 4, four spines on the third endopodal segment of leg 4. To the genus Giardella, Hemicyclops caissarum Kihara and Rocha and H. carinifer Humes are assigned, in addition to Giardella ricoensis n. sp., Giardella callianassae Canu, and G. thompsoni A. Scott. Keys to the species of both genera are provided.

  • We discovered a syrphid species, Tropidia rostrata Shiraki, 1930, for the first time in Korea. This is the first member of the genus Tropidia recorded in Korea. This species can be distinguished from other Palaearctic members of Tropidia by the combination of the following characteristics: lower facial margin strongly protrudes forward; apical 3/4 of hind femur black; and tergites 2 and 3 each with a pair large yellowish brown square spots (not reached hind margin). We here provide a detailed redescription supplemented by the color photographs of external structures including genitalia. We also discussed the status of primary types associated with this taxon.

  • Numerical identification was aplied for Streptomyces sp.264, an isolate producing a new restriction endonuclease Sdi I. The restriction enzyme would appear to be an isoschisomer of Xho I. Fifty taxonomic unit characters were tested and the data obtained were analyzed numerically by using the TAXON program. The isolate was identified to be the major cluster 19 of Streptomyces and best matched to S. diastatochromogenes. It was, therefore, concluded that the isolate was identified to be a member of Streptomyces diastatochromogenes.

  • Chemotaxonomy and numerical identification were carried out for an isolate strain No.8001 producing an antibiotic that generates oxygen radical. The genus of strain No.8001 was decided as Streptomyces sp. from chemotaxonomic data. Thirty-nine taxonomic unit characters were tested and the data were analyzed numerically using the TAXON program. The isolate was best matched to Streptomyces citreofluorescens in the major cluster 1B of Streptomyces. Therefore, it was concluded that the isolate was identified to be a member of Streptomyces citreofluorescens.

  • We reported an unrecorded plant species, Galium bungei var. miltorrhizum (Hance) Jeong & Pak in Korea. This species is found in Gyeonggi-do, Chungcheongbuk-do, Jeollabuk-do, Gyeongsangbuk-do, and Gyeongsangnam-do. G. bungei var. miltorrhizum is distinguished from related taxa by glabrous stem and glabrous or rarely short papillate mericarps. This taxon was named 'Dung-geun-ne-ip-gal-kwi' in Korean based on shapes of leaves. We provided a description, illustrations, photographs, and a key of related taxa in Korea. And we propose a new combination (Galium bungei var. miltorrhizum).

  • A taxonomic and floristic account for Korean Elachista is provided. All previously reported taxa from Korea are reappraised. Elachista in Korea consists of five species: E. falcata Lee sp. nov., E. nipponica Umezaki, E. okamurae Yoshida, E. orbicularis (Ohta) Skiner, and E. tenuis Yamada. Elachista fucicola (Vell.) Aresch. 1. typica Rosenvinge sensu Kang (1966) that was previously recorded in Korean flora was assigned to another taxon, E. okamurae Yoshida. Elachista taeniaeformis Yamada is transferred to the new genus, Proselachista Lee et Garbary. Elachista falcata is characterized by having a pseudoparenchymatous medulla, assimilatory filaments with equal diameter over their entire length and small projections on the lower portion, falcate paraphyses, and gourd-shaped unilocular sporangia.

  • The relationships and character variations on 5 taxa of Calystegia were examined by sluster analysis and principal component analysis. Thirteen Calystegia population samples from the middle part of Korea were observed. Although minor differences were noted, essentially similar results were obtained from the phenograms by UPGMA, UPGMC and Ward's clustering methods, and these results were in accordance with those obtained from the ordination plots by principal component analysis. C. soldanella is distantly connected with the other taxa mainly because of its morphologically different leaf organs. Based on the difference on the first principal component, C. hederacae is kept apart from the rest 3 taxa. In the relationships among C. japonica, C. sepium var. americana and C. davurica, mivor differences were obtained from the 3 clustering methods. As to the character variations among different populations within a taxon, they are slight in C. soldanella and C. sepium var. americana, but remarkable in C. hederacae and C. davurica.

  • Adenostemma madurense DC. (Asteraceae, Adenostemma L.), which is known to be distributed in Japan, Taiwan, Thailand and Nepal was recently found on Jeju Island in Korea. It is morphologically allied to A. madurense but distinguished from A. lavenia (L.) Kuntze by having such characters as broadly ovate or ovate to oblong leaves, $15-21cm\;long{\times}7-12cm$ wide and smooth achenes with slightly muricate at the upper. Furthermore, A. madurense is found in dry mountain slopes in evergreen forests while Adenostemma lavenia occures in the wetland and side of pond. This taxon was named 'San-mul-meo-wi' in Korean based on its habitat. We provide a description, illustrations, photographs, and the key to the related species in Korea.

  • In the screening of fungal diversity, two strains were collected from the soil of Yeongcheon and dissected guts from the bodies of Chinese rice grasshopper (Oxya chinensis), Chinese grasshopper (Acrida cinerea), and Far eastern devil grasshopper (Oedaleus infernalis) from Daejeon in Korea. They were identified as Umbelopsis vinacea (KNU-YC-1801B) and Mucor hiemalis f. corticola (KNU-20F7, KNU-20F8, KNU-20F9). Multigene phylogenetic analyses of the internal transcribed spacer (ITS) regions, and large subunit (LSU) sequence data confirmed two unreported taxa along with their morphology. The results of molecular phylogeny firmly supported the detailed description and illustration for each taxon. As far as we know, both Umbelopsis vinacea and Mucor hiemalis f. corticola are the first reported taxa in Korea.

  • Previous surveys on Ulleung-do (Dagelet Isl.) found just ten earthworm taxa while the current survey unearthed a dozen species. Placement of parthenogenetic 'tube' Amynthas dageletensis Hong & Kim, 2005 is resolved as it clearly belongs in synonymy of Metaphire soulensis (Kobayashi, 1938) which becomes a new Ulleung-do record. Other new megascolecids are recorded since Amynthas heteropodus (Goto & Hatai, 1898) and A. baemsagolensis Hong & James, 2001 are confirmed as synonyms of A. corticis (Kinberg, 1867) and A. carnosus (Goto & Hatai, 1899), respectively. The latter taxon is differentiated and its synonym A. pingi (Stephenson, 1925) provisionally revived. New lumbricids are Bimastos parvus (Eisen, 1874), Eisenia japonica (Michaelsen, 1892) and questionably Dendrodrilus rubidus (Savigny, 1826). All confirmed species are common exotics with no endemics. Drawida moniligastrids were not yet located on this remote island for reasons unknown.
