0D2587DA941D74724AD4E83E1027FE9F.taxon	description	Description. Phagotrophic euglenid. Cells are 9 - 11.8 μm long, ventrally flattened and dorsally convex. There is a hyaline semicircular collar (Fig. 1 a, arrowhead) around the short anterior neck (Fig. 1 c, 1 e, arrowheads). The cells have five dorsal ridges running along the cell (Fig. 1 b, 1 d). On the ventral side there are three fine ridges. The right and left ventral ridges arise at the neck. The left ventral ridge curves slightly from the anterior to the posterior forming an arc. The mid-ventral ridge arises from a small protrusion near the anterior end of the cell. Two flagella are unequal in length and are slightly thickened. The anterior flagellum is 1.2 - 1.3 times the cell length and the re- current posterior flagellum is 0.6 - 1.0 times the cell length (Fig. 1 e). The flagellar reservoir lies anteriorly in the right hand side of the cell (Fig. 1 f, arrow) and the nucleus in the left hand side (Fig. 1 a). The cells move by gliding. Previously reported cell length. 9 - 10 μm (Lee and Patterson, 2000). Habitat. Marine intertidal sediments. World distribution. Australia (Lee and Patterson, 2000), Korea. Deposition.

0D2587DA941D7472493DEE521027F9A5.taxon	description	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. 1 i, 1 j, 1 l, arrowheads). The anterior flagellum is only visible as a dis- tinct structure within the sleeve (Fig. 1 j, 1 k). A posterior flagellum trails under the left margin, and sometimes is long enough to extend beyond the back of the cell (Fig. 1 g- 1 k). 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. 1 h, 1 k, 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). Habitat.

0D2587DA941D7471493DEA8715FFF8EE.taxon	description	Description. Cells are oval or globular in shape, 4.5 - 7.0 (avg. 5.7) μm long and rigid. The cells have a small rostrum in the anterior end (Fig. 1 m, 1 o, 1 q, arrowheads), behind which two flagella insert. The active anterior flagellum is short and is 0.3 - 0.4 times the cell length, and bends slightly ventrally. The longer posterior flagellum is 1.3 - 1.8 times the cell length and trails posteriorly. This species is common in freshwater habitats. This genus is morphologically similar to the genera Heteromita and Neoheteromita.

0D2587DA941E74704953E96515C0F907.taxon	description	Description. Cells are 5.6 - 10.9 (avg. 8.4) μm and very plastic. The anterior flagellum is 1.8 - 2.3 times the cell length and sweeps gently. The posterior flagellum is 1.7 - 2.2 times the cell length and may attach to the cell body. Lamellar, finger-like and filose cytoplasmic strand is drawn from the posterior end of the cell (Fig. 2 d). Lamellar and finger-like pseudopodia are all over the cell, but predominantly on the left side of the cell (Fig. 2 d, arrowheads). 1 - 2 contractile vacuoles are seen; usually on the right side of cell, and the other in posterior half (Fig. 2 a, 2 c).

The anterior flagellum is 1.3 - 1.5 times the cell length and the posterior flagellum is 1.3 - 1.5 times the cell length. The cells rarely form finger-like and bulbous pseudopodia at the posterior end. The nucleus has a coarse appearance; the nuclear envelope is very thin but many microbodies attach to it, the nucleolus is slightly irregular, there are many granules and rods in the nucleoplasm. The nucleus is closely connected to the basal bodies (Fig. 2 e, 2 i). Cytoplasmic strand is drawn out from the posterior end of the cell, but may not be seen (Fig. 2 h). The single large contractile vacuole is located in the posterior or lateral part of the cell (Fig. 2 i). The cells move by gliding and consume bacteria.
