  • Two new harpacticoid species of family Thalestridae are described on the basis of the specimens collected from the shallow sublittoral sand bottom or seagrasses of rocky shore in South Korea. Dactylopusia pauciarticulata n. sp. is discernible from its 19 congeners by the 6-articulated antennule. Paradactylopodia koreana n. sp. most resembles P. striata Kunz, 1973 of its seven congeners, but obviously distinguished from it by the shape of male leg 2 endopod.

  • Thalestridae과의 하르팍티쿠스류에 대한 분류학적 연구의 일환으로, 혹 형성과 등 양식 해조류에 심각한 피해를 일으키는 것으로 주목받고 있는 Parathalestris속의 하르팍티쿠스류를 조사한 결과 1신종(P.parviseta n. sp.) 4한국미기록종(Parathalestris bulbiseta Lang, 1965; P. verrucosa Ito, 1970; P. pacificus Tschislenko, 1971; P. areolata Ito, 1972)을 포함하여 6종을 동정.분류하였다. 본 논문에서는 1신종과 4미기록종에 대한 삽화와 분류학적 고찰 및 한국산 Parathalestris속 6종에 대한 검색표를 작성하였다.

  • 1994년부터 주로 한국의 조간대 해조류 및 아조하대 바닥 퇴적물을 걸러 채집하여 보관중이던 Thalestridae과의 갈고리노벌레류를 재검토한 결과 Phyllothalestris sarsi Sewell, 1940와 Dactylopusia falcifera Willey, 1935의 2종을 추가로 동정하였다. 이 종들은 태평양에서 처음으로 보고되는 종이다. 2종 모두 원기재가 부족하여 한국산 표본을 재료로 하여 재기재를 하였고, 근연종과의 형질비교 및 변이성 등에 관하여 고찰하였다.

  • Two marine harpacticoid copepods are newly recorded from Korea : Eudactylopus specitabilis (Brian, 1923) and E. andrewi Sewell , 1940. Six species are currently recognized in the genus Eudactylopus, multitidue of which were often disputed among authors on their taxonomic status, so we treat here the taxonomic features of the two species above on the basis of specimens from South Sea and East Sea of Korea. E.spectabilis occurred first outside the Mediterranean Sea. and is fully redescribed with illustrations. Important male characters like the shape of leg 2 endopod and leg 5 with its setal arrangement are particularly emphasized as the diagnostic characters.

  • Paramenophia platysoma (Thompson and Scott, 1903) is newly reported from Korean waters based on the materials collected from several seagrass and algal bed habitats. The Korean materials of P. platysoma in the present study coincide well with the original description of the species with respects to the characteristic features of the first, fourth, and fifth legs, and in most respects to P. platysoma sensu $Gam{\hat{o}}$ (1969) reported from Japan except for the antennary exopod. However, they show some differences to P. platysoma sensu Pallares (1973, 1975) reported in Argentina, in terms of the morphology of the fifth leg in females and the second leg in males. Detailed description and illustrations of P. platysoma are provided for both sexes. The morphological features of Paramenophia species are discussed and a key to the species of genus is provided.

  • Two harpacticoid copepods, Pseudonsiella longicaudata. n. sp. and Xylora longiantennulata n. sp. belonging to the subfamily Donsiellinae are described. They were found in the wood infested by isopod of the genus Limnoria from the East Sea (Sea of Japan), Korea. The former species is characteristic in having the long caudal ramus and four setae on mandi bular basis. The latter one closely resembles X, nertica Hicks in general body form, but is clearly distinguished from X. nertica in that the antennule is much longer and the caudal ramus is longer, and leg 5 endopod bears four setae.

  • A new species of Eudactylopus Scott A., 1909 is described from the southern coast of Korea. The specimens were collected using a light trap set overnight at the entrance near a pier. Eudactylopus yokjidoensis n. sp. is similar to E. andrewi Sewell, 1940 and E. spectabilis (Brian, 1923) in two key respects: similar length of proximal and distal inner setae on female P2 enp-2, and modification of two subapical setae on male P2 endopod. However, E. yokjidoensis can be differentiated from the two species by following morphological characteristics: in females, the length ratio of cephalothorax/2nd-4th thoracic somites combined is smaller in E. yokjidoensis than other two species (1 : 0.8 vs. 1 : 1); antennule has nine segments (vs. 7-segmented in E. andrewi); P2 to P4 each bears a process in medial distal margin of basis, while it is just smooth in E. spectabilis; in males; the length ratio of cephalothorax to 2nd-4th thoracic somites combined is smaller in E. yokjidoensis than other two species (1 : 0.6 vs. 1 : 1 in E. andrewi and 1 : 0.8 in E. spectabilis); and P5 exopod has a comb-like innermost seta, while it is bipinnate seta in E. spectabilis. To prove the Korean species of Eudactylopus to be new, full descriptions of both sexes are given here, and the claim is supported by distinct genetic differences between E. yokjidoensis and E. spectabilis (22.3-22.7%) in the mitochondrial gene cytochrome oxidase subunit I(mtCOI) sequence.
