  • Three Loxodes ciliates collected from estuarine littoral, wetland and small pond in Korea, were identified as Loxodes kahli Dragesco and Njin$acute{e}$, 1971, L. magnus Stokes, 1887 and L. vorax Stokes, 1885. The descriptions for these species based on living and protargol impregnated specimens were given. Morphometry, illustrations and microphotographs were also provided. Diagnoses of three species are as follows. Loxodes kahli; size in vivo $160-300{\times}40-70\;{\mu}m$; oral area with reddish to brownish pigments; 6-11 macronuclei arranged linearly; 5-9 micronuclei located near macronuclei; 4-12 M$\ddot{u}$ller's vesicles; somatic kineties on right 18-20 and left 2 in number. L. magnus: size in vivo $250-470{\times}87-15\;{\mu}m$; body colored dark brown; 5-13 macronuclei; 8-13 micronuclei; 8-18 M$\ddot{u}$ller's vesicles; somatic kineties on right 23-26 and left 2 in number. L. vorax: size in vivo $70-160{\times}20-35\;{\mu}m$; oral area with brownish pigments; 2 macronuclei; 1 micronucleus located between macronuclei; 2-4 M$\ddot{u}$ller's vesicles; somatic kineties on right 18-20 and left 2 in number.

  • The subfamily Murinae is a very controversial group concerning their phylogenetic relationship. Previous studies could not resolve phylogeny among four genera Apodemus, Micromys, Mus and Rattus of the Muridae. In the present study, eight rodent species resident in South Korea were collected and phylogenetically analyzed based on sequence data of five mitochondrial and nuclear DNA regions: 12S rRNA, cytochrome b gene (cyt b), cytochrome oxidase II (COII), control region of mitochondrial DNA, and a thyroglobulin (Tg) of nuclear DNA. According to the phylogeny of the concatenated data, M. musculus separated early in Murinae (ML 100%; BA 1.00 pp) and the genus Rattus grouped with the harvest mouse, M. minutes; these were separated from the genus Apodemus with relatively strong support (ML 74%; BA 0.76 pp). The Siberian chipmunk population was also examined using the five genes to obtain better resolution. The phylogeny for Korean rodents determined using the 12S rRNA, cyt b, COII and control regions discriminated the Siberian chipmunk populations from Korea, Russia, and China.

  • Two oxytrichid ciliates collected from the mosses and estuarine littoral in Korea were identified as Oxytricha longigranulosa Berger and Foissner, 1989 and O. marina Kahl, 1932. These species are reported for the first time from Korea. The description was based on living and protargol impregnated specimens. Diagnostic characters for each species are as follows. Oxytricha longigranulosa: Cell in vivo $80-115{\times}30-50{\mu}m$, mostly $90{\times}40{\mu}m$. Length/width ratio about 2.4/1. Cortical granules about $1{\times}1.5{\mu}m$ in size, colorless, arranged in short and discontinued longitudinal rows. Four frontoventral cirri. Adoral zone of membrane lies (AZM) covering 30-50% of cell length with 25-27 adoral membranelles (AM). Buccal area flat, typical Oxytricha pattern. Five transverse cirri, 19-23 right marginal cirri, 19-24 left marginal cirri, three caudal cirri, five dorsal kineties. Two macronuclear nodules 2 in number and spherical in shape, two micronuclei in number. Oxytricha marina: Cell in vivo $100-150{\times}30-60{\mu}m$. Cytoplasm colorless without cortical granules. Four frontoventral cirri. AZM covering 50% of cell length with 28-44 AMs, Buccal area flat, typical Oxytricha pattern. Five transverse cirri, 23-38 right marginal cirri, 19-25 left marginal cirri, three caudal cirri, five dorsal kineties. Two macronuclear nodules and spherical in shape, 1-5 micronuclei, mostly two in number.

  • Samples of ho subspecies of striped field mice, Apodemus agrarius coreue & Apodemus ograrius cheiuensis, from four localities in Korea were used for the analyses of mitochondrial DNA fragment patterns resulted from the digestion with eight restriction enzvmes. A total of 31 fragments were recognized and 15 clones were revealed. The 15 clones were grouped into four major subgroups. One sample from Cheongiu was distinct, and formed one of the four major subgroups: the mean divergence wi6 other subgroups was 4.6 per cent, and extensive analyses using samples from various sites are necessary to clarify the taxonomic status of the subgroup. Samples from Cheju island constituted another subgroup, and they should be named as hpodemus cheiuensis. Samples from Wan island composed still another subgroup, and thew seemed to be another population of Apodemus chejuensis: further analvses are needed for the classification of Apodemus cheiuensis. In the last subgroup composed of six of seven samples from Cheongiu and four samples from Haenam, two samples from Cheonsiu and one sample from Haenam were identical in their mitochondrial genotypes, indicating that these striped field mice from Cheongiu and Haenam have close maternal relationship.

  • 진도의 해안 간극수에서 채집한, 고리선충목의 사각고리선충아속에 속하는 1신종을 기재한다. 이 종은 사각고리선충아속의 44개 고리를 가진 7기록종 중에서, 두부강모의 형태가 유사하고, 머리의 전단부가 넓게 잘린 점, 6개의 유두모양 입술돌기를 가진다는 점. 가늘고 긴 교미침을 공통적으로 가진다는 점등에서 T. (Q.) crassicomides Timm, 1970과 가장 유사하다. 그러나 수컷에서, 끝에서 두 번째 고리에 구근 모양의 돌기를 가지며, 꼬리 부분이 7개의 고리로 이루어지고, 등쪽 강모가 9쌍이라는 점에서 위 종과 뚜렷이 구별된다. 이 신종은 사각고리선충아속에 속하는 해양 자유선충으로서는 동아시아 해역에서의 첫 번째 기록이다.

  • Branchinotogluma segonzaci (Miura and Desbruyères, 1995) occurs in hydrothermal vent fields of the southwestern Pacific Ocean. We morphologically compared B. segonzaci from the North Fiji Basin with the original description from the Lau Basin and a subsequent study of specimens from the Manus Basin. The main characteristics of all B. segonzaci populations were similar having 21 segments, 10 pairs of elytra, cylindrical-shaped anterior lobes, and ventral papillae on segment 12 and ventral lamellae on segments 13-17 in males. However, the specimens from the North Fiji Basin had rounded to sub-renifrom elytra rather than oval in the original description. Additionally, we newly obtained 11 cytochrome oxidase subunit I (COI) DNA barcodes from the North Fiji Basin and Tonga Arc populations and compared them with known COI DNA barcodes of Branchinotogluma species. Thirteen sequences of B. segonzaci showed 0.0-1.07% intraspecific variation and formed two clades in the COI neighbor-joining tree, whereas the interspecific variation among Branchinotogluma species was 8.19-22.4%. The results of this study contribute to biogeographic studies of B. segonzaci and the evolution of polynoid scale worms in chemosynthesis-based ecosystems.
