Mormonilla phasma is redescribed, based on the specimens from the Northeastern Pacific. M. phasma in the study area has the following morphological characteristics; second endopodal segment of mandible partly fused to basis and a distinct three-segmented exopod of mandible in anterior view and one indistinct segment in posterior view which are different from the description given by Boxshall (1979). In addition the first and the second endopodal segments of leg 1 were also separated indistinctly. Other morphological characteristics are similar to those reported in previous studies. The morphological anomalies in endopodal segments of the leg 1, unknown up to now are also discussed. This study is the first report on the distribution of M. phasma in the Northeastern Pacific.

The napuliar stages of Harpaciticus nipponicus Ito reared in the laboratory are descirbed and illustrated in detail. Ovigerous females of h. nipponicus were collected from the intertidal zone of Kuryongpo Yougil-gun Kyongangbuk-do. Korea. This species passed through 6 naupilar stages before metamorphosis to the first copepodid stage. At $20^{\circ}C$, the first copepo양 stage was attained in 6-8 (mean 7 ) days after hatching. The nauplii of Harpacticus species can be distinguished from those of other Harpacticid genera by the maxillule, pereiopods, and caudal setae. The nauplii of h. nipponicus are similiar in morphology to those of H. uniremis but distinguished by the differences in naupliar size and appendage setation. A key to identify the naupliar stages of this speices is briefly discussed.

A harpacticoid copepod, Sinamphiascus dominatus Mu & Gee, 2000 is re-described from the sandy bottom in off Jeju Island of Korea. The genus Sinamphiascus was established with single species, S. dominatus from the Bohai Sea, China. The main diagnostic characters of the specimen from Korea are well matched with the original description, although it has minor discrepancies including the lengths and ornamentation of setae in leg 6 of both sexes, shape of the base on furcal setae and teeth number of labrum in female. However those discrepancies are regarded to the intra-specific variations. This is the first record of genus Sinamphiascus in Korean waters.

An anthessiid copepod ; Anthessius atrinae n.sp., is described based on the specimens recorved in the mantle cavity of Atrina pectinata (Linn) taken from Korean waters. This is distinguished from congeners by formula II, I, 5 on distal segment of exopod of the fourth leg, three terminal claws on distal segment of the second antenna , and the shape of caudal ramus.

Peltidium quinquesetosum n. sp. belonging to the family Peltidiidae is described from algal bed on subtidal rocky bottoms of Korea. The most characteristic features of this species are found in the setal number of distal segment of leg 1 endopod and the shape of leg 5 in female, and the caudal rami fully concealed by urosome in a dorsal view.

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.

As a result of the faunistic study on the subterranean cyclopoid copepods, four species of three genera in the family Cyclopidae are reported from nine limestone caves and a lava tube in South Korea: Megacyclops magnus (Marsh, 1920), Acanthocyclops orientalis Borutzky, 1966, A, robustus (Sars, 1863) and Diacyclops suoensis Ito, 1956, all of them new to Korean fauna. This paper deals with the taxonomic accounts and illustrations of the four species with the redescription of A. orientalis. This is the first taxonomic study on the cave-dwelling cyclopoid copepods from Korea.

A new genus Goodingius is proposed to incorporate Hemicyclops adhaerens(Williams), H. arenicolae Gooding, H. elongatus Wilson and H. subadhaerens Gooding, all of which bear the six-segmented female urosome, three mandibular elements (or three elements plus one rudimentary setule), five setae on the first antennular segment, and no inner coxal seta of leg 4. The genus Giardella Canu, a sister taxon of Goodingius, is redefined as possessing eight elements on the third exopodal segment of leg 3, only a single inner seta on the second endopodal segment of leg 4, four spines on the third endopodal segment of leg 4. To the genus Giardella, Hemicyclops caissarum Kihara and Rocha and H. carinifer Humes are assigned, in addition to Giardella ricoensis n. sp., Giardella callianassae Canu, and G. thompsoni A. Scott. Keys to the species of both genera are provided.

Four harpacticoid species belonging to the family Tachidiidae are reported from the coastal waters and salt marshes in South Korea: Tachidius discipes Giesbrecht, 1881, Neotachidius parvus Huys, Ohtsuka, Conroy-Dalton and Kikuchi, 2005, Microarthridion litospinatus Shen and Tai, 1973 and Geeopsis incisipes (Klie, 1913). The latter two species and genera are new to Korean fauna. The previous record of T. discipes reported by Song and Chang (1995) from Korea is affirmed by the finding of male specimens. Microarthridion litospinatus is first known outside the type locality, and redescribed herein in detail. A key to the five species and four genera of the family Tachidiidae hitherto known from South Korea is presented.

The larvae of Nitocra spinipes Boeck, 1865 were reared at 2$0^{\circ}C$ and 33.3$\textperthousand$ in the laboratory. These species passed through six nauplii stages and the first copepodid appeared in 8-10 days. Nauplii of N. spinipes is distinguished by characteristics of the appendage setation and caudal setae. The number of segments of antennal and mandibular exopodites in harpacticoida is discussed within familial level.
