  • Acanthochondria spirigera is redescribed based on the specimens recovered from the Lophiomus setigerus in the southern coast of Korea. This parasitic copepoda is distinguished from congeners by the possession of spirally twisted egg-strings. Acanthochondria spirigera(Chondracanthidae, Poecilostomatoida) is the first recorded species from Korea. This parasitic copepod was not found on the fish in May. Relative density and prevalence also decreased from January to May. A. spirigera live symbiotically within the pharyngeal cavity of the L. setigerus, and eat oesophageal mucous string of their hosts. The male of the parasitic copepoda is dwarf, and found on the ventral surface of genital segment of the female.

  • Ergasilus zacconis (Yamaguti, 1936), the copepod parasite originally named as Pseudergasilus zaconnis, is redescribed based on the specimens newly collected from the freshwater fish Zacco platypus (Temminck and Schlegel) from Japan. Some errors appearing in the original description are emended. An explanation for the generic position of this species is given.

  • A species of the parasitic copepods Phrixcephalus unbellatus (Lernaeide ; Cyclopoidea) from Branchiostegus japonicus is described and reported for the first time in Korea. The parasite was recovered from the eye of host. P. umbellatus was easily identified by the body shape extensive ramification of the antennal processes and numerous branches on the thoracic horns, The parasite inserted its head and the anterior portion of thorax up to the 4th segment in the eye ball of the host through a narrow hole which it usually burrowed near the upper margin of the cornea above the crystalline lens. Prevaklence of the parasite increased from 3.3% January to 11.9% in June.

  • Parabrachiella bera (Yamaguti, 1939) is redescribed based on newly collected material from multicolorfin rainbowfish, Parajulis poecilopterus, landed at Wando fishery port on the southern coast of Korea. Although some differences were observed between the original description and the specimens examined in this study, these differences do not warrant a change in the taxonomic status of this species. Parabrachiella bera bears some resemblance to Parabrachiella incurva Shiino, 1956, but differs from it in details of the trunk and genital processes.

  • Lepeophtheirus tuberculatus, n. sp., is described from the greenlings Hexagrammos otakii and H. agrammus from the Sea of Japan off Mangreung, Korea. This species has been confused with L. scuttger Shiino, 1952 and L. sheni Boxshall and Bellwood, 1981. However, the new species apparently differs from the latter two species.

  • Six new species of the genus Enalcyonium are described as parasites of octocorals of New Caledonia. They are Enalcyonium lobophyti, E. humesi, E. caledonensis, and E. auriculatum from the alcyonacean Lobophyton schoedei Moser, E. capillatum from the gorgonacean Rumphella antipathes (L.), and E. bullatum from the gorgonacean Siphonogorgia variabilis (Hickson). This is the first record on the species of Enalcyonium from the South Pacific.

  • Two parasitic copepods, poecilostomatoid Colobomatus mylionus Fukui, 1965 and siphonostomatoid Clavellisa chinensis ($Y{\ddot{u}}$, 1933), were reported for the first time from Korea and redescribed based on the females collected from the marine fish of Korean waters. The C. mylionus was collected from the blackhead seabream, Acanthopagrus schelegelii(Bleeker). Colobomatus mylionus had been frequently reorded from marine teleost fishes from of Eden, Newcastle, Brisbane, Yelloon, and Point Sampson. The second record was C. chinensis redescribed based on the speciemens collected from the gills of a Japanese grenadier anchovy, Coilia nasus Temminck and Schlegel. Some differences were observed between the orginal description of known specimens examined in this study, these differences do not warrant a change in the taxonomic staus of the two species. The attachment site of all two copepods reported from Korea were the cephalic sensory canals and gills.

  • Twelve species in five genera of parasitic copepods are recorded from seventeen species of freshwater fishes of Korea. They are Ergasilus coniformis n. sp., Ergasilus ventriosus n. sp., E. briani Markewitsch, E. peregrinus Heller, Neoergasilus joponicus (Harada) N. lonsispinosus Yin, N. inflatus Yin, N. bullatus n. sp., N. angustus n. sp., Sinergasilus undulatus (Markewitsch), Lernaea cyprinacea L., and Lamproglena chinensis $Y{\"{u}}.$ As the most prevalent parasitic copepod, Neoergasilus japonicus is found to parasitize as many as ten species of freshwater fishes in Korea. The fish Zacco platypus, from which seven species of parasitic copepods are discovered, turned out to be the most preferred host of the parasitic copepods in this country. Full descriptions are given of the new species and new records of Korea. Lamproglena chinensis, an incompletely known species, is also redescribed.ibed.
