  • This study summarizes the taxonomic notes and distribution of 13 taxa of the genus Scenedesmus (Chlorophyceae) collected from several swamps, reservoirs, and rivers throughout South Korea from 2012 to 2014. In this study, light microscopy images of all 13 taxa are presented and briefly discussed with regard to their taxonomy, distribution, and ecology and environmental factors of occurrence sites. All 3 subgenera (subgenus Scenedesmus 1 taxon; subgenus Acutodesmus 2 taxa; subgenus Desmodesmus 10 taxa) are newly described in Korean freshwater algal flora: S. linearis, S. acuminatus var. elongatus, S. acuminatus var. tetradesmoides, S. carinatus, S. denticulatus var. disciformis, S. gutwinskii var. heterospina, S. helveticus f. bicaudatus, S. lefevrei, S. oahuensis var. clathratus f. longiclathratus, S. oahuensis var. clathratus, S. pannonicus, S. polydenticulatus, and S. tenuispina.

  • 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.

  • 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.

  • 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.

  • The genus Ephedrus Haliday, 1833 is a large taxon of Aphidiinae, consisting of 48 valid species in the world. This genus is considered to be important as a biological control agency, which includes solitary koinobiont parasitoids on aphids. One of its interesting characteristics is both male and female have 11-segmented antennae. In previous study, this genus was subdivided into three subgenus, Breviephedrus, Ephedrus and Fovephedrus, based on molecular and morphological characters. In this study, one Ephedrus species is firstly recorded from South Korea. Since it has been collected from Geumsan-gun in 2005 and deposited as dried specimen at Naturalis Biodiversity Center in Netherland, we recently confirmed it. Description and illustrations of the E. lacertosus are provided.

  • Psalidoremus is one of the subgenus which consists of five species and eleven subspecies through Taiwan, Japan, Korea and north eastern part of China which present strong endemism to their distribution. While most of advance studies focus on the new species or subspecies from this taxon, this paper suggests paleogeographical assumption and hypothesis of how they diverged from common ancestors. Phylogeographical patterns illustrated by the distribution of five species, which including Prosopocoilus inclinatus, Prosopocoilus hachijoensis, Prosopocoilus dissimilis, Prospocoilus pseudodissimilis, Prosopocoilus motschulskii respectively, has been assessed in this research. Speciation history is suggested by morphological tendencies especially in male mandibles with assumption from geographical patterns of under sea level.

  • Surveys on Jeju-do (Quelpart Isl.) unearthed about 40 earthworm species or sub-species. Several considered new to science are described. Only a dozen were previously known and these are taxonomically reviewed. The two most commonly recorded in surveys by S. Kobayashi in the 1930s were Drawida anchingiana Chen, 1933 and Metaphire quelparta (Kobayashi, 1937), neither recently relocated. Morphologically similar taxa, supported with DNA barcodes, for Moniligastridae, are Drawida anchingiana seogwipo, D. anchingiana halla and D. iucn spp. or sub-spp. nov. For Megascolecidae, new taxa and synonyms are: Amynthas arx and A. aucklandis spp. nov. that have seminal grooves rather than the eversible male pores of Metaphire plus Amynthas simplex is another new species. Amynthas sangumburi Hong & Kim, 2002 is recognized as a probable new synonym within the A. corticis (Kinberg, 1867) species-group while Amynthas corticis saeseum sub-sp nov. is described. Amynthas gracilis (Kinberg, 1867) is a new record from Jeju and Korea (with A. bouchei, A. omodeoi and A. edwardsi all by Zhao & Qiu, 2009 possible synonyms of this species group from China) with a Jejuan sub-species, A. gracilis insularum, sub-sp. nov. Presence on Jeju of Amynthas carnosus (Goto & Hatai, 1899) is confirmed (its further new synonyms are Chinese A. fuscus Qiu & Sun, 2012 and A. taiwumontis Shen et al., 2013), as is A. micronarius (Goto & Hatai, 1898) (with new synonym A. montanus Qiu & Sun, 2012 also an invalid secondary homonym). Amynthas phaselus maculosus (Hatai, 1930) is in new combination with A. kamitai (Kobayashi, 1934) and A. minjae Hong, 2001 syns. nov. Two newly described Metaphire quelparta sub-spp are M. q. seogwipo and M. q. valhalla these being supported with DNA barcodes despite the nominal taxon not yet being confirmed.

  • This review provides a comprehensive summary of the PCR primers and profiles currently in use in our laboratory for red algal DNA barcoding and phylogenetic research. While work focuses on florideophyte taxa, many of the markers have been applied successfully to the Bangiales, as well as other lineages previously assigned to the Bangiophyceae sensu lato. All of the primers currently in use with their respective amplification profiles and strategies are provided, which can include full fragment, overlapping fragments and what might best be called "informed overlapping fragments", i.e., a fragment for a marker is amplified and sequenced for a taxon and those sequence data are then used to identify the best primers to amplify the remaining fragment(s) for that marker. We extend this strategy for the more variable markers with sequence from the external PCR primers used to "inform" the selection of internal sequencing primers. This summary will hopefully serve as a useful resource to systematists in the red algal community.

  • Rhododendron keiskei Miq. var. hypoglaucum Suto & Suzuki (Ericaceae) was found in Yeosu-si, Jeollanam-do, Korea. This species is distinguished from related taxa in Korea by lepidote hairs entire, flower-bud terminal, inflorescences umbel-like racemes, corolla lepidot outside, white tinged with yellow. This taxon was named 'Seom-Jin-Dal-Lae' in Korean based on its habitat. We provide its description, illustrations, photographs and a key of related taxa in Korea.

  • Eleocharis parvula (Roem. & Schult.) Bluff, Nees & Schauer (Cyperaceae), was found in Ganghwa-gun, Incheon Metropolitan City in Korea. This species is distinguished from related taxa in Korea by its small fusiform tubers, culms without septa when dry, 3-fid stigmas and style base confluent with the apex of achene. This taxon was named 'Gaet-ba-neul-gol' in Korean based on its habitat. We provide its description, illustrations, photographs and a key to the related taxa in Korea.
