  • A harpacticoid species, Paramphiascella fulvofasciata Rosenfield and Coull, 1974, belonging to Miraciidae Dana, 1846 is newly reported from Korean waters. The species is mostly related with P. pacifica Vervoort, 1962, however, it is easily distinguished by the typical structure of male P2 in having 1 large spine and 2 setae on P2 enp-2. Korean materials represented some discrepancies from the original description of P. fulvofasciata in the detailed structures of mouth parts. The present study is a first record of the genus Paramphiascella Lang, 1944 from Korean waters.

  • Only 12 species of marine harpacticoid copepods are ercorded in Koran waters. With the study on the taxonomy of harpacticoid copepods in Korean waters, Lourinia armata(Claus, 1866) was found in the samples from the rocky shore of Names off the east coast and Chiju Hrbor in June and August 1992, respectively. This species is reported to be distributed in the far east Asian coasts for the first time. It was redescribed and figured.

  • Three harpacticoid copepods, Dactylopodamphiascopsis latifolius (Sars, 1909), Diosaccus ezoensis Ito, 1974 and Ambunguipes rufocincta (Brady, 1880) are recorded as new to the Korean fauna with illustrations, on the basis of the specimens collected mainly from the marine macro algae during the period from June 1990 to September 1997.

  • Four harpacticoid species belonging to genus Attheyella were confirmed from South Korea: Attheyella (Attheyella) coream Miura, A. (A.) paucisetosa Chang and Kim, A. (Mrazekiella) byblis Chang and Kin, and A. (M.) tetraspinosa, n. sp. The new species and the male of A. (A.) paucisetosa are described. A. (M.) tetraspinosa, n. sp. most resembles A. baikalensis Borutzky, but readily distinguished from it and its relatives by the extraordinarily elongated leg 5 exopod and the female leg 5 basipod bearing four spines on it.

  • The spatial patterns of meiobenthic communities in deep-sea sediment were examined. Sediment samples for analyzing of meiobenthic community structure were collected using a remote operated vehicle (ROV), multiple corer TV grab at 20 stations at five sites. In all, 15 meiofauna groups were recorded. Nematodes were the most abundant taxon. Benthic foraminiferans, harpacticoid copepods, polychaetes, and crustacean naupii were also dominant groups at all sites. The total meiofauna density at the study sites varied from 49 to 419 ind./$10cm^2$. The maximum density was recorded at a site located in Challenger Deep in the Mariana trench where simple benthic foraminifera with organic walls flourish. These distinctive taxa seem to be characteristic of the deepest ocean depths. Active hydrothermal sediments contain up to 150 harpacticoid copepods per $10cm^2$ of sediment. In a inactive ridge sediments, devoid of macrofaunal organisms:, the abundance of harpacticoid copepods never exceeded 15 ind./$10cm^2$. Multivariate analysis (multidimensional scaling) revealed significant differences in community structure among the three regions; near an active hydrothermal vent, in the deepest ocean depths and at typical deep-sea bed sites.

  • Three harpacticoid species of the genus Onychocamptus are reported from the inland waters of South Korea: O. vitiospinulosa (Shen and Tai), O. mohammed (Blanchard and Richard) and O. bengalensis (Sewell). Of these, O. vitiospinulosa and O. mohammed are newly added to Korean copepod fauna. Onychocamptus vitiospinulosa is redescribed. Systematic accounts on the morphological details and the intraspecific variabilities are provided with a key to the Onychocamptus species from Korea.

  • Canthocamptus morimotoi Miura, a cave-dwelling harpacticoid species belonging to C. mirabilis species group, is fully redescribed and illustrated on the basis of the material newly collected from the type locality, Simpigul Cave, South Korea. C. morimotoi is the only genuine subterranean species in the C, mirabilis group, and claimed to be a relict species restricted to its type locality. The sexually isomorphic ornamentation of the outer terminal seta on the distal exopodal segment of male leg 4 and the well-developed spines on the disteromedial corner of anal somite are the most significant features differentiating this species from ther members of the mirabilis-group.

  • Six phytal harpacticoid species of the genus porcellidium are recorded from 22 algal species in the eastern (Sea of Japan) and southern (Korea Strait) coast of Korea. Among these six species, Porcellidium ofunatense Harris and Iwasaki and Porcellidium gamoi(Harris and Iwasaki) are recorded as new to Korean fauna. Other four species are described as new to science: Porcellidium bipartitum n. sp. found from a single algal species, Procellidium wandoensis n. sp. from ten algal species, Porcellidium acutum n. sp. from five algal species, and Porcellidium brevlcacum n. sp. from two algal species. It is found that the associations between the species of Porcellidium and macroalgae reveal weak specificities.
