        Two Litonotid Ciliates (Ciliophora: Litostomatea: Pleurostomatida)Unknown from Korea

        이정미,윤재술,신만균 한국동물분류학회 2006 Animal Systematics, Evolution and Diversity Vol.22 No.2

        Two litonotid ciliates collected from the freshwater habitats in Korea were identified as Loxophyllummeleagris(Mller, 1773) and Siroloxophyllum utriculariaeobservation of living and protargol impregnated specimens, and biometric analysis. Their diagnosticcharacteristics are as follows. L. meleagris; 163-480× 80-100 m in vivo, body shape lancet or knife-like;dorsal margin with 10-19 extrusome warts; 8-35 macronuclei nodules, like a string of bead; 16-21 somatic-11 on left side (including perioral kinety 1); 1contractile vacuole located at posterior part at diastole stage, extending along the dorsal margin towardanterior end with a single long narrow canal. S. utriculariae; 110-170× 78-150m in vivo, body shape lancetlike; dorsal margin without extrusome warts; 2 macronuclei, spherical; 12-19 somatic kineties on right side,3- -3 contractile vacuoles, first one located anterior ventrally,second one located posterior dorsally and last one located near posterior end of cell.

        Three Freshwater Lembadion Ciliates (Peniculida, Lembadionidae) Newly Reported from Korea

        김성훈,윤재술,윤성명,신만균 한국동물분류학회 2017 Animal Systematics, Evolution and Diversity Vol.33 No.4

        Three freshwater ciliates, Lembadion lucens (Maskell, 1887) Kahl, 1931, L. bullinum (Müller, 1786) Perty, 1849, and L. magnum (Stokes, 1887) Kahl, 1931, belonging to the genus Lembadion Perty, 1849 are newly reported from Korea with detailed descriptions and illustrations based on live observation and protargol impregnation. Lembadion lucens is characterized by following characteristics: 52-91×33-64 μm body size in vivo; ovoid and slightly asymmetric body shape; 27-49 somatic kineties; and 55-80% of whole pellicle covered with meridional lines with rectangular meshes in posterior portion. Lembadion bullinum is distinguishable from its congeners by its body size of 110-130×60-73 μm in vivo; ovoid body shape; oral aperture occupying about four-fifths of ventral side; 48-55 somatic ciliary rows; meridional lines with rectangular meshes except anterior portion (about 16% of body) on pellicle. Lembadion magnum is also characterized by its body size of 70-90×37-50 μm in vivo; obliquely asymmetric anterior end of body; oral aperture occupying about more than four-fifths of ventral surface, and opened longitudinally entire ventral surface; 45-61 somatic ciliary rows; meridional lines without rectangular meshes on whole pellicle of body. The present study is the first description of the genus Lembadion from Korea.

        First Record of Three Loxodes Ciliates (Ciliophora: Loxodida: Loxodidae) from Korea

        김지혜,권춘봉,윤재술,신만균 한국동물분류학회 2009 Animal Systematics, Evolution and Diversity Vol.25 No.3

        Three Loxodes ciliates collected from estuarine littoral, wetland and small pond in Korea, were identified as Loxodes kahli Dragesco and Njiné, 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 160-300×40-70 μm; oral area with reddish to brownish pigments; 6-11 macronuclei arranged linearly; 5-9 micronuclei located near macronuclei; 4-12 Müller’s vesicles; somatic kineties on right 18-20 and left 2 in number. L. magnus: size in vivo 250-470×87-15 μm; body colored dark brown; 5-13 macronuclei; 8-13 micronuclei; 8-18 Müller’s vesicles; somatic kineties on right 23-26 and left 2 in number. L. vorax: size in vivo 70- 160×20-35 μm; oral area with brownish pigments; 2 macronuclei; 1 micronucleus located between macronuclei; 2-4 Müller’s vesicles; somatic kineties on right 18-20 and left 2 in number.
