Only four copepod species associated with sea stars have beenknown from the north Pacific . The examination of Korean sea stars for copepod associates revealed two species ; Scottomyzson gibberum and a new species belonging to the genus Synstellicola. Both species are (re) described. S. gibberum , A sole member of the genus hitherto known only from the northeastern Atlantic , is recorded in this report to be associated with various sea stars and distributed widely in Korean seas.

As a result of this report, the pseudoscorpion family Chthoniidae in Korea comprises nine species in four genera. All species are collected mainly from the litter layer in wooded forests. The two new species, Tyrannochthonius suppressalis n. sp. and Tyrannochthonius spinatus n. sp., described herein occur on islands in the Yellow Sea.

Cawjeekelia iksana sp. n. is described from South Korea. The family Haplodesmidae, the genus Rhipidopeltis Miyosi, the species Rhipidopeltis sinuata Miyosi, and Hyleoglomeris emarginata Golovatch are recorded in Korea for the first time. The genus Megalotyla Golovatch as well as the species Cawjeekelia pyongana Mikhaljova and Kim, Tokyosoma ronkayi (Shear) and Yamasinaium koreanum Golovatch, are new to the fauna of South Korea.

The present study of hourse-hair worms was based on the materials collected from 17 areas in Korea during the period from October 1986 to June 1992. As a result the identified Korean horse-hair worms consist of 2 species in 1 genus. One is new species, Gordius lineatus n. sp. and the other, Gordius robustus Leidy, 1851 is newly recorded in South Korea. Total 6 species in 2 genera are now listed for the gordioidean fauna of Korea.

This paper deals with floristic and taxonomic accounts of 47 taxa of the genus Trachelomonas collected from 58 waters in Korea. Of these, 19 taxa are added to the Korean Trachelomonas flora, and 4 taxa, T. curta var. reticulata, T. koreana, T. planctonica var. papillosa, and T. spina are newly recorded in the world flora of the euglenoids. Detailed description and illustrations are given for each species. Since 23 taxa are previously reported in the Korean freshwaters, a total of 70 taxa are listed up in the Korean Trachelomonas flora. Trachelomonas species are abundant and diverse in old or stagnant swamps or ponds, where is enriched with organic matters and nutrient salts. T. bacillifera, T. hispida, and T. volvocina formed water blooming in the natural swamps or fishery ponds in spring and summer.

Twelve species in five genera of parasitic copepods are recorded from seventeen species of freshwater fishes of Korea. They are Ergasilus coniformis n. sp., Ergasilus ventriosus n. sp., E. briani Markewitsch, E. peregrinus Heller, Neoergasilus joponicus (Harada) N. lonsispinosus Yin, N. inflatus Yin, N. bullatus n. sp., N. angustus n. sp., Sinergasilus undulatus (Markewitsch), Lernaea cyprinacea L., and Lamproglena chinensis $Y{\"{u}}.$ As the most prevalent parasitic copepod, Neoergasilus japonicus is found to parasitize as many as ten species of freshwater fishes in Korea. The fish Zacco platypus, from which seven species of parasitic copepods are discovered, turned out to be the most preferred host of the parasitic copepods in this country. Full descriptions are given of the new species and new records of Korea. Lamproglena chinensis, an incompletely known species, is also redescribed.ibed.

Although Sumunmulbangdui wetland at the Halla Mountain in Jeju Island, a kind of montane wetlands, has been considered to bear high biodiversity, no study has been reported on the bacterial diversity. In this study, soil and water samples were collected from the wetland in order to isolate novel bacterial species. Bacterial strains belonging to the phyla Bacteroidetes, Firmicutes, and Actinobacteria were isolated after spreading soil and water samples onto solid agar media. The 16S rRNA gene sequences of the strains assigned to the three phyla were compared to those of type strains of the species in the phyla. The strains that showed less than 98.7% 16S rRNA gene sequence similarity to the validly published species were considered to be novel species candidates. A total of 32 strains were regarded as novel species candidates in the phyla Bacteroidetes, Firmicutes, and Actinobacteria. Diversity of novel species candidates was very low; the candidates were confined to only few genera. In the Bacteroidetes, 13 novel candidate species were affiliated with the genera Mucilaginibacter, Sphingobacterium, Pedobacter, Flavobacterium, and Chryseobacterium. A total of 13 novel candidate species that assigned to the genera Paenibacillus Lysinibacillus, and Bacillus were identified in the phylum Firmicutes. Only two candidate species that belonged to the genera Mycobacterium and Nocardia were excavated in the Actinobacteria. Cultural, physiological, and chemotaxonomic characteristics have been determined for the novel species candidates, and the characteristics are described in this study.

A new species of draconematid nematode, Paradraconema jejuense n. sp., is described from the shallow sublittoral coarse sediments of Jeju Island, Korea. Paradraconema jejuense n. sp. is most similar to P. antarcticum Allen and Noffsinger, 1978 in having similar habitus (long slender body) and amphideal fovea (doubled elongate spiral in male and circular spiral in female), but is distinguished by the following characteristics: larger number of posterior sublateral adhesion tubes (10 in male and 11-12 in female) and subventral adhesion tubes (16 in male and 17-18 in female), fewer cephalic acathiform setae on rostrum (a pair of small cephalic acathiform setae in both sexes), the absence of eye-spots, and the presence of a differentiated lateral field in mid-body region. This is the first taxonomic report on Paradraconema species from Korea.

About 450 specimens of Lockeia were discovered from the lacustrine siltstone of the Early Cretaceous Jinju Formation of Jin Island, southern coast of Korea. They are very elongated, seed-shaped Lockeia characterized by a large size, mostly 60-70 mm long and 15-20 mm wide. They are characteristically sharp longitudinal furrow bounded by steeply inclined both margins, elevated marginal rims and sharp pointed both longitudinal furrow ends. This trace fossil is herein described as Lockeia gigantus ichnosp. nov. Plicatounio, a freshwater bivalve which does not occur occurs occasionally within Lockeia gigantus is regarded as the most-likely producer of this resting trace fossil. This new trace fossil represents the largest Lockeia ever known and the first record of Lockeia from the Cretaceous non-marine deposits in the world. This fossil also represents an unusual example of resting trace fossil (Lockeia) associated with a possible producer (bivalve Plicatounio) lived in community in the shallow lacustrine environment.
