  • Both sexes of a new species of Miraciidae belonging to the genus Amonardia Lang, 1948 are described. All materials collected from the cultivated brown alga, Undaria pinnatifida of Gijang, Korea. So far only one species, A. normani (Brady, 1872) from the algal bed at Jindo Island was recorded in Korea. The new species can easily be distinguished from its congeners by the combination of characters as follows: (1) shape of first antennular segment in female, (2) setal formular of mandible and maxillule, (3) setae of female sixth leg in female, and (4) shape of P2 endopod and exopod of fifth leg in male.

  • The family Ameiridae Boeck, 1865 (Copepoda; Harpacticoida) consists of about 380 species in 47 genera, but only 10 species have been reported in Korea. A benthic ameirid species was collected from the East Sea of Korea. Specimens were identified as members of the genus Ameiropsis Sars G.O., 1907, and this is the first record of the genus Ameiropsis in the Pacific Ocean. Ameiropsis gyeongjuensis sp. nov. is morphologically similar to A. mixta Sars G.O., 1907 and A. longicornis Sars G.O., 1907 from Norway. However, the new species is clearly distinguishable from the others based on the following morphological characteristics: the proximal segment of antennary exopod with a bulge in the middle, and with one pinnate seta; the distal segment of antennary exopod with a thickened, blade-shaped outer seta; and female P5 baseoendopod with five setae and exopod with six setae. An identification key to species is provided for the 11 valid species of the genus Ameiropsis.

  • Three new species of Kelleria are described based on the females from the invertebrate burrows in the Port Seogwipo, Jeju Island, Korea. These species possess in common no process on the inner margin of the free segment of leg 5. Kelleria grandisetiger n. sp. possesses a large seta on lateral sides of the genital double-somite and a small thumb-like process near base of the free segment of leg 5. Kelleria undecidentata n. sp. possesses the elongated free segment of leg 5 which is more than four times as long as wide and 11 teeth on the distal margin of the second maxillary segment. Kelleria portiviva n. sp. possesses one seta and one distinct spine on the distal margin of the free segment of leg 5, ten or 11 teeth on the distal margin of the second maxillary segment, and a tuft of spinules on the convex outer comer of mandible.

  • Three species of the genus Centropages(C. calaninus, C. orsinii, and C. sinensis) were newly collected from Korean waters. The Korean specimens were consistent with previous descriptions, but differ in the following characteristics: in C. orsinii male right antennule with spine on dorsoposterior surface of each segment XIII and XIV; distal end of segment XIX with humplike process on dorsal surface; in C. calaninus female long spinelike process on second exopodal segment of leg 5 of reaching 1/2 length of terminal spine on third exopodal segment; in male, first endopodal segment of leg 5 without inner seta; left second exopodal segment serrated on distal margin; and in C. sinensis male distal spine of left second exopodal segment of leg 5 not fused with segment. In this study, key characters for species identification also were provided.

  • Three Pleuromamma copepods were newly collected from the South Sea of Korea in the summer when the Tsushima Warm Current was strong. They were identified as Pleuromamma abdominalis(Lubbock, 1856), P. indica Wolfenden, 1905, and P. xiphias (Giesbrecht, 1889). Although these species have been reported in world oceans, they were first reported from Korean waters. So far, four species of Pleuromamma (P. borealis Dahl, 1893, P. gracilis Claus, 1863, P. piseki Farran, 1929, and P. robusta (Dahl, 1893)) have been recorded in Korean waters. We provided re-description of these three species insufficiently described by previous authors and key characters for species identification in addition to species hitherto known in Korea.
