한국 가거도에서 채집된 모래해면속(망각해면목: 가는실해면과)의 2 신종, 버키스트모래해면(Psammocinis bergquisti n. sp.) 과 가거모래해면(P. gageoensis n. sp.)을 기색한다. 버키스트모래해면은 외형이 엄지손가락 모양이며 지금까지 알려진 모래해면 속의 종들은 좁고 단순한 형태의 2차섬유를 갖는 반면 본 신종은 2차섬유가 얇은 판 모양이거나 넓은 망구조이다. 가거모래해면은 모슬모래해면(P. mosulpia Sim. 1998) 과 외형에서 매우 유사하지만, 1차섬유가 복잡한 총생모양으로 섬유 내부에 있는 모래와 골편들의 겉으로 잘 보이지 않은 점이 특징이다. 가거모래해면의 1차섬유 속에는 모슬모래해면의 1차섬유 속의 모래보다 작은 모래들이 있다.

인천연안에서 채집한 부유성 빈모류인 Pelagostrobilidium simile의 형태 형성과정을 pyridine silver carbonate impregnation 염색법을 이용하여 관찰하였다. p. simile의 형태형성은 전형적인 hypoapokinetal mode로 입섬모열은 모세포의 체섬모와 관계없이 독립적으로 세포막 안에서 외부로 노출되는 입원기로부터 형성되었다. 입원기는 anarchic field의 증식으로 외부 입섬모열 아래에서 시작되었다. 딸세포 prefer와 opisthe의 체섬모상은 분열하는 동안 기저체의 증식으로 모세포 체섬모 구조로부터 나왔다. 모세포의 입 기구는 딸세포 prefer로 전달되고 모세포의 입섬모구조에서 입기구의 새로운 형성은 관찰되지 않았다.

울릉도와 가거도에서 2001년 10월과 2000년 7월에 SCVBA 다이빙으로 채집된 해면동물을 동정$\cdot$분류한 결과 유령해면속 (Clathria)의 곰바위유령해면[Clathria (Clathria) gombawuiensis n. sp.]과 가거유령해면 [ Clathria ( C.) gageoensis n. sp.]이 신종으로 밝혀졌다. 곰바위유령해면은 Clathria (C.) conica와 골편의 구성에 있어서는 유사하지만 골편의 크기와 성장형태에 있어서 많은 차이가 있었으며, Clathria (C.) conica는 작은 toxa를 가지지 않는다. 가거유령 해면은 Clathria (C.) hexagonopora와 유사하지만 골편의 크기와 성장형태가 다르고, Clathria (C.) hexagonopora는 작은 toxa를 가지지 않는다.

The Korean peninsula has diverse habitats and so would be expected to have a rich millipede fauna because of its location between the Paleoarctic and Oriental regions. To facilitate studies on millipedes, this work provides an updated list and discussion of Korean millipedes. A total of 69 species had been recorded up to 2010, but since then no new species have been reported. Among 69 species, 49 are endemic to the Korean peninsula. From 1950 to the present, an average of only seven new species from the Korean peninsula has been described per decade. This number does not reflect the biodiversity of millipedes in Korea, especially when compared to Taiwan, which has only one-third the area of the Korean peninsula, but from which a greater number of millipede species have been recorded (75 vs. 69 species). Japan has twofold the land area of the Korean peninsula, and an almost threefold higher number of millipede species. Further, more-intensive surveys will likely result in identification of more millipede species in the Korean peninsula.

Korean nannastacids have recorded only eight species belonging to genera Campylaspis and Cumella. In this paper, Nannastacus nyctagineus Gamȏ, 1962, is redescribed and illustrated as a new species of Korean fauna in this study for the first time. Korean female specimens of Nannastacus nyctagineus correspond well with the original description by Gamȏ, 1962 based on only female specimens. Gamȏ has described that new species, Nannastacus pruinosus could be distinguished from N. nyctagineus based on only male specimens. The Korean male specimens of N. nyctagineus undoubtedly match well with the description of N. pruinosus with the following common features: the surface of the carapace is covered with numerous granules; pereonites and pleonites have similar patterns of the teeth on dorsal surface; the proportion and armature of the dactylus of pereopod 2 is similar; the number and pattern arrangement of the setae on the surface in antenna 1, pereopod 1, and uropod are the all most same. Nannastacus pruinosus Gamȏ, 1962 is proposed as a synonym of N. nyctagineus described in this study. This represents the first record on the genus Nannastacus from Korea.

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.

Vermamoeba vermiformis is a very important free-living amoeba for human health in association with Legionnaires' disease and keratitis. This interesting amoeba was firstly isolated from a freshwater of Dokdo (island), which was historically used for drinking water. Trophozoites and cyst forms of V. vermiformis strain MG1 are very similar to previous reported species. Trophozoites of V. vermiformis strain MG1 showed cylindrical shape with prominent anterior hyaline region. The average ratio of length and width was about 6.5. Typically, cysts of the strain MG1 showed a spherical or slightly ovoidal shape with smooth wall, and lacked cyst pores. Some cysts had crenulate-walled ectocyst, which was separated from endocyst wall. Further, 18S rRNA gene sequence of V. vermiformis strain MG1 showed very high similarity to other V. vermiformis species (99.4%-99.9% identity). Molecular phylogenetic analysis based on 18S rRNA gene sequences clearly confirmed that the isolate was one strain of V. vermiformis with maximum bootstrap value (maximum likelihood: 100%) and Bayesian posterior probability of 1. Thus, the freshwater of Dokdo in Korea could harbor potentially pathogenic amoeba that may cause diseases in humans.

Heterotrichous ciliates were isolated from marine and brackish habitats in Korea, and their morphology, infraciliature and morphometrical characters were investigated using silver impregnated methods. These three Condylostoma species were identified as Condylostoma curva Burkovsky, 1970, C. minutum Bullington, 1940 and C. spatiosum Ozaki and Yagiu in Yagiu, 1944. The species of Condylostoma based on morphology are highly variable in most of characters and distinguished as following. Condylostoma curva is oval to elongate ellipsoidal, size about $245{\times}100{\mu}m$ in vivo, and conspicuously dark greenish brown with cortical granules on their surface, buccal cavity relatively large about 40% of body length, 5-11 macronuclear nodules, 4-8 frontal cirri serially arranged and 22-38 somatic kineties. Condylostoma minutum is elongate ellipsoidal and the size about $310{\times}55{\mu}m$ in vivo, buccal field about 35% of body length, 12-20 macronuclear nodules, adoral zone consisted of 82-107 membranelles, large and long one frontal cirrus and 38-44 somatic kineties. Condylostoma spatiosum is large elongate ellipsoidal, size about $670{\times}105{\mu}m$ in vivo, buccal cavity about 25% of body length, 11-25 macronuclear nodules, 111-144 adoral membranelles, membrane-like 2 frontal cirri, 49-74 somatic kineties. These three Condylostoma species are described here for the first time in Korea.

To identify Korean red-backed voles (Myodes regulus) from Korea by mitochondrial DNA (mtDNA) sequencing, we obtained mtDNA control region sequences of 17 red-backed voles from Korea and northeast China, and these sequences were compared with the corresponding haplotypes of Myodes obtained from GenBank. We identified five red-backed voles from Mt. Changbai and Harbin as M. rufocanus and another three redbacked voles from Harbin as M. rutilus, respectively. Moreover, nine red-backed voles from Korea, showing the average nucleotide distance of 0.66% among nine haplotypes, were different from other species of Myodes, and the average distance between nine haplotypes of red-backed voles from Korea and seven haplotypes of M. rufocanus was 6.41%, whereas the average distance between nine haplotypes of red-backed voles from Korea and five haplotypes of M. rutilus was 14.8%. We identified the red-backed voles from Korea as M. regulus, and found that M. regulus is distinct in its mtDNA control region sequences as well, although we propose further analyses with additional specimens from East Asia using nuclear and mtDNA markers to confirm the distinctness of M. regulus.
