  • Recent molecular and polyphasic taxonomic approaches toward bacterial systematics have played a significant role in revolutionizing our insight in the taxonomy of bacterial organisms. This advance has also contributed greatly to delineation of new taxa from bacterial organisms isolated from a variety of natural sources of Korea. Recently, many bacterial organisms have isolated from soil, seawater, foods, wastewaters and humans of Korea and have been subjected to polyphasic taxonomic study. From the results of this study, some isolates have been found to be members of new genera and new species.

  • Two unrecorded species, Brachynervus beijingensis and B. confusus are described from South Korea for the first time. A taxonomic study of the South Korean Brachynervus was initiated by Uchida (1955). Until now only one species, B. tsunekii, has been recorded from South Korea. In the study, we provide the diagnoses and photos of two unrecorded species of Brachynervus.

  • Pagurus is the most diverse hermit crab genus in Korea. In this study, the cytochrome c oxidase subunit I (COI) and 16S rRNA of 24 individuals from four Korean Pagurus species (i.e., 7 Pagurus brachiomastus, 8 P. proximus, 8 P. simulans, and 1 P. rectidactylus) were sequenced and analyzed. No genetic difference was found between the COI and 16S rRNA sequences of P. brachiomastus and P. simulans, and the COI sequences of P. rectidactylus and P. quinquelineatus (comparative species from NCBI). Considering the morphological and ecological characteristics together, we assume that P. simulans and P. rectidactylus are subspecies of P. brachiomastus and P. quinquelineatus, respectively. This study should facilitate further research on the taxonomic status of these species.

  • The Fucales plants have very homogenous taxonomic characteristics at order level, but show many morphological variatations at species or subspecies levels. This study is one of the serial works to obtain more taxonomic data than morphotaxonomic ones and to clarify the taxonomic ranks and characteristics of Korean Fucales plants through physiological and biochemical analyses. Total lipid compositions of Korean Fucales plants were analyzed by the 3-dimensional TLC method. Major components of phospholipids (PA, PC, PG, PE, DPG, LPE, LPC), neutral fat TG and sterols were commonly contained in each species. Unknown lipids X1, X2 and X3 were contained in genus Sargassum, but Hizikia was lacking X3 and Myagropsis was lacking both X2 and X3. The latter contained unique X8. From the view-point of the phylogeny of lipid metabolism, Sargassum might be more closely related to Hizikia than to Myagropsis. A variant of S. patens from Seongsan showed minute metabolic difference from that of the typical plant; but a variant of S. serratifolium did not show any significant difference from that of the typical plant.

  • A taxonomic review of the Korean Lycocerus (Cantharidae, Coleoptera) was presented. Through this study, total of four species were found from Korea including a species new to Korea, Lycocerus striatus. We newly provided a key to the Korean Lycocerus species and the distributional map on each species in this study.

  • A taxonomic study on the marine sponges was conducted with the materials collected from Chujado Island, Korea during the period June 2001 to May 2005 by SCUBA and hands. They were classified into 63 species, 31 genera, 25 families, seven orders in a class. Among them, Antho (Arcania) manarensis Carter, 1880 and Eurypon lendenfeldi Hentschel, 1912 were newly added to Korean Fauna. Two species, Biemna chujaensis and B. jeolmyongensis, were new to science.

  • Following the taxonomic reassignment of Schizopora and some Hyphodontia species into Xylodon, we confirmed nine Korean species of Xylodon in a previous study. In the present study, we propose Korean names for these Xylodon species according to the Principles of the Mycological Terminology Review Committee of The Korean Society of Mycology.
