Description. Cells are ovate to elliptical and 4.5-7.1 (avg. 5.5) μm long. The proboscis (see Heiss et al., 2015) with a slow to-and-fro motion emerges from the anterior right margin of the cell, and comprises the anterior flagellum surrounded by a membranous sleeve ( Fig. 1i, 1j, 1l View Fig , arrowheads). The anterior flagellum is only visible as a dis- tinct structure within the sleeve ( Fig. 1j, 1k View Fig ). A posterior flagellum trails under the left margin, and sometimes is long enough to extend beyond the back of the cell ( Fig. 1g-1k View Fig ). It moves by a slow, even gliding. The cell body is plastic but not amoeboid, and is deformed during turn- ing. Swimming is not seen. Strands of cytoplasm may be trailed from behind the cell ( Fig. 1h, 1k View Fig , arrows). The nucleus is in the anterior left part of the cell. Food vacuoles contain bacteria and detritus.
Previously reported cell length. 4.5-7 μm ( Larsen and Patterson, 1990).
