  • The Antarctic freshwater copepod, Boeckella poppei (Mrazek, 1901), has the widest range of distribution extending from southern South America to Antarctic continent, among all Boeckella species. Boeckella poppei is the only freshwater copepod known to be inhabiting the Antarctic continent. In present study, we analyzed the DNA barcodes of the mitochondrial cytochrome c oxidase subunit I (COI) gene of B. poppei from King George Island, Antarctica. The intraspecific genetic distances varied from 0% to 13% and interspecific genetic distances ranged from 11% to 14%. The overlap of DNA barcode gap suggests careful threshold-based delimitation of species boundaries.

  • Material of a Bryocamptus species, formerly reported as B. umiatensis Wilson, 1958 from Sakhalin and South Korea, is here recognized as a distinct new species. Specimens of both sexes were recently obtained from an alpine wetland, Sumeunmulbaengdui, located in the Hallasan National Park, Korea, and newly registered as a Ramsar Wetland in 2015. The new species, B. jejuensis n. sp., differs from the type population of B. umiatensis from Alaska by the smooth margin of the anal operculum in both sexes, the peculiarly modified terminal seta on the distal endopodal segment of the male leg 3, the sword-like spinous seta on the distal endopodal segment of the male leg 4, and the presence of a setule row on the inner distal margin of the caudal rami in the female. Both sexes of the new species are described in detail with particular reference to the male characters. A revised key to the seven species of the genus Bryocamptus Chappuis, 1929 occurring in Korean waters is provided.

  • 17종의 한국산 담수 어류로부터 5속 12종의 기생성 요각류가 발견되었다. 이들은 피라미낫벌레 (Ergasilus coniforemis n. sp.). 배불뚝낫벌레 (Ergasilus ventriosus n. sp.), 장구머리낫벌레 (E.briani Markewitsch). 쏘가리낫벌레 (E.peregrinus Heller). 풍선신낫벌레 (Neoergasilus inflatus Yin), 일본신낫벌레 [Neoergasilus japonicus (Harada)], 큰가시신낫벌레 (N. longispinosus Yin), 뚱보신낫벌레 (N. builatus n. sp.), 흘쭉신낫벌레 (N. angustus n. sp.), 키다리중국낫벌레 [Csinergasiius undujatus (Markewitsch)]. 닷벌레 (Lernaea cyprinacea L.), 중국민물아가미붙게 (Lamproglena chinensis Yu)이다. 일본 신낫벌레는 한국에서 가장 흔한 담수어류 기생성 갑각류로서 10종의 담수어류에 기생하는 것이 발견되었다. 또한, 피라미는 한국에서 가장 다양한 갑각류가 기생하는 숙주로서, 7종의 요각류가 이 어류에 기생하는 것이 발견되었다. 발견된 기생성 갑각류 중에서 신종과 한국 미기록종을 기재하였다. 과거에 기재가 불완전하게 이루어진 중국민물아가미붙게도 재기재하였다.

  • Canthocamptus morimotoi Miura, a cave-dwelling harpacticoid species belonging to C. mirabilis species group, is fully redescribed and illustrated on the basis of the material newly collected from the type locality, Simpigul Cave, South Korea. C. morimotoi is the only genuine subterranean species in the C, mirabilis group, and claimed to be a relict species restricted to its type locality. The sexually isomorphic ornamentation of the outer terminal seta on the distal exopodal segment of male leg 4 and the well-developed spines on the disteromedial corner of anal somite are the most significant features differentiating this species from ther members of the mirabilis-group.

  • In order to clarify the species composition of freshwater zooplankton community inhabiting Lake Sochonji and chonji on the top of Mt. Paektu, the present study have been carried out based on the materials collected during the periods from 24 to 25 July, 1997. As a result of examing the specimens, from the Lake Chonji, a total of 10 species (Keratella cochlearis cochlearis, K. quadrata quadrata, K. valga valga, Notholca squmula squmula, Colurella adriatica adriatica, Lepadella patella patella, Lecane hua luna, L. (Monostyla) bulla bulla, Cephalodella gibba gibba, philodina roseola) appeared rotifers only. >From the lake Sochonji, a total of 7 species were identified. It consists of 3 species (Keratella valga valga, Cephalodella gibba gibba, Asplanchna (Asplanchnella) brightwelli) of rotifers, 2 species (Daphnia hyalina, Alona quadrangularis) of cladocerans, and 2 species (Acanthodiaptomus pacificus, Bryocamptus zschokkei caucassicus) of copepods, respectively. Also, appeared nauplius of copepoda.

  • A genuine interstitial cyclopoid species belonging to the genus Psammophilocyclops Fryer, 1956 is recorded from the filtration basin of a water treatment plant, South Korea. The genus Psammophilocyclops is very rarely found, and only three species have been recognized as yet: P. boccaroi Fryer, 1956 from Africa, P. trispinosus Shen et Tai, 1964 and P. bispinosus Shen et Tai, 1964 from China. The present new species differs from the congeneric species by the character combination of 11-segmented antennule in female, four-segmented maxilliped with 2,1,1,2 setation, the spine formula of 3,3,3,3, and setal arrangement of 3,3,5,3 on the distal endopodal segments of legs 1-4. Descriptio and taxonomic accounts of the new species are presented with a revised generic diagnosis and a key to the species hitherto known in the genus.
