Abstract :A new ciliate species Colpodidium zelihayildizae n. sp., which was discovered in a dry irrigation channel in Van insert ignore into journalissuearticles values(Turkey);, was investigated morphologically using standard live and silver impregnation methods, and its SSU rRNA gene phylogeny was provided. This new species was characterized as follows: body size about 40−60 × 15−20 μm in vivo, elongated ellipsoidal with flat or slightly concave ventral surface; the buccal cavity slightly below equatorial plane; macronucleus spherical or slightly elliptical, usually located in the last third of the cell; cortex distinctly furrowed in the anterior half; 19–22 somatic kineties, 4 postoral kineties; paroral membrane has 20 dikinetids; 3 nassulid organelles insert ignore into journalissuearticles values(NOs);, with NO1 very close to the left edge of the paroral membrane, which consists of 1 dikinetid pair. Phylogenetic analyses conducted on the SSU rDNA sequences determined that Colpodidium zelihayildizae was clustered with Colpodidium caudatum and formed a clade with Apocolpodidium etoschense and Colpodididae sp.
