Glissandra similis Lee, 2006

Figs 5i–j

Description: Cells are rigid, 5–6 µm long, elliptical and slightly flattened laterally. The cells have a small depression at the anterior part of the cell and a longitudinal ventral groove extending from the depression to the posterior end of the cell. Two flagella are thickened and slightly unequal in length, and insert subapically into the depression. The tip of the anterior flagellum moves back and forth, and the trailing posterior flagellum may lie in the ventral groove. During gliding, the cells usually appear to move obliquely. Sometimes common.

Remarks: This species was firstly reported from marine sediments in tropical Australia ( Lee 2006b). It can be distinguished from G. innuerende because it is elliptical and somewhat laterally flattened while G. innuerende is ovoid and dorso-ventrally flattened. In addition, Glissandra similis has a longitudinal ventral groove extending from the anterior depression to the posterior end of the cell while G. innuerende has a small depression subapically and has a structure on the ventral side of the cell.
