| contents | <p><b><i>Kurnaimonas celeris</i> Lee nov. spec. (Figs 1l, 4e–f)</b></p><p><b>Diagnosis:</b> Cell oblong, 14 to 15 µm long, dorso-ventrally flattened and rigid. With two flagella of unequal length into wide ventral depression. With small protrusion separating insertion of flagella. Moving by fast swimming.</p><p><b>Etymology:</b> The name refers to ‘fast’.</p><p><b>Observation:</b> Cells are oblong, 14 to 15 µm long, dorso-ventrally flattened and rigid. The anterior part of the cell forms relatively a wide depression, which continues to a mid-ventral groove on the right side of the cell. The cells have a small protrusion, which is directed laterally and may separate the insertion of the flagella. The cells have two flagella, which are in the same strength and are not acronematic. The anterior flagellum inserts anterio-laterally into the ventral groove and is slightly longer than the cell. The posterior flagellum inserts just below the anterior flagellum, is about 2 times the length of the cell and appears to lie in the ventral groove. When the cells are moving, the anterior flagellum is directed to the front and beats in a sinewave, and the posterior flagellum beats also in a sinewave and directs posteriorly. The cells often contain large food particles in the posterior end of the cell. The cells move very fast by swimming. Rarely observed.</p><p><b>Remarks:</b> This organism is similar to <i>Pseudophyllomitus granulatus</i>, but is distinguished because its posterior flagellum has an undulating beating pattern when swimming and because it is rigid and flattened. It is similar to <i>Platychilomonas psammobia</i> in being flattened and cell length, but <i>P. psammobia</i> has two rows of extrusomes and a coiled posterior flagellum when it is inmobile. This species may be distinguished from other swimming flagellates by its flagellar orientation. It was also reported from intertidal marine sediments in Korea under the name ‘Protist 2’ (Lee 2002b).</p> |
