  • 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.

  • Copepods play an important role as a primary consumer in the various aquatic ecosystems. Most of marine benthic copepods belong to the Order Harpacticoida, and are known over 3,000 species in the world. Research on the biodiversity of the benthic copepods are important in the development of the new bio-resources, and the genetic resources. The importances and the prospects of biodiversity research on the mavins benthic copepods are discussed.

  • 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.

  • A new species of Nitokra and Ameira parvula (Claus) belonging to the family Ameiridae are recorded from brackish waters in South Korea. Nitokra koreanus n. sp. most resembles N. spinipes and N. pietschmanni, however, it is characteristic in having the character combination of ellipsoidal P5 exopod and very short P1 enp 1. Ameira parvula is reported for the first time from the Northwestern Pacific. Description of the new species and the taxonomic accounts of both species are presented.

  • Two subterranean harpacticoid species are recorded from cavern and interstitial waters in South Korea: Parastenocaris ondali n. sp. and P brevipes Kessler, 1913. Parastenocaris ondali n. sp. resembles P nipponensis Chappuis, 1955 from Japan, but differs from it by shorter caudal rami, armature of leg 5, and short endopodal processes of leg 4 in both sexes. Herein, the new species is described, and systematic accounts of both species are provided with detailed illustrations.

  • 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.

  • Two species of the family Porcellidiidae associated with hermit crabs are described from Korean seas. These are Porcellidium similis, new species collected from Pagurus similis, Pagurus pectinatus and Porcellidium brevicaudatum Kicks & Webber collected from Dardanus impressus. The new species resemble closely Porcellidium brevicaudatum in general body form, but is clearly distinguished from Porcellidium vrevicaudatum in that the caudal ramus is weakly oblique in tis distal border and the lobe of leg 5 is more slender.

  • A taxonomic study on the genus Nitakra (Ameiridae) is accomplished. A total of five species are collected from coastal marshes, lagoons, and estuaries in South Korea. Among them, the latter three species are newly recorded from Korea: N. spinipes Boeck, N. affinis califarnica Lang and N. pietschmanni (Chappuis). Taxonomic accounts and a key to the species from Korea are given.
