  • 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.

  • 생산 하르팍티쿠스목의 갑각류는 지금까지 우리나라에서 12종이 기록되어 있을 뿐이다. 한국의 해산 하르팍티쿠스목 요각류의 분류를 연구하기 위하여 한국산 해조류를 조사한 결과 1992년 6월과 8월에 각각 동해안의 남해와 제주항에서 Lourinia armata(Claus, 1866)가 채집되었다. 이 종은 동북아 연안에서 최초로 보고되는 것이며, 이에 한국산 미기록종으로 재기재하고 도판을 작성하였다.

  • 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.

  • 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.

  • 동해 및 남해의 22종의 해조류에 서식하는 Procellidium 속의 요각류 6종을 기재하였다. 이 중에서 Porcellidium ofunatense Harris and lwasaki와 Porcellidium gamoi(harris and Iwasaki)는 한국내 미기록종이다. 나머지 4종은 신종으로 기재하였으며, 이들은 1종의 해조에서 발견된 Procellidium bipartitum n. sp., 10종의 해조에서 발견된 P.wandoensis n. sp., 5종의 해조에서 발견된 P. acutum n. sp., 그리고 2종의 해조에서 발견된 P. brevicacum n. sp.이다. Porcellidium 속의 종과 해조류 사이의 특이성은 낮게 나타났다.
