Description: Cells are about 20 µm and flexible. A structure is seen on the left ventral side of the cell. Two flagella emerge subapically. The anterior flagel- laum is about the cell length and beats freely. The posterior flagellum is 1.3–1.8 times the cell length and appears to adhere tightly to the cell body in a ventral groove. Neither flagellum is acronematic. The cytoplasm contained many small particles. The nucleus is located in the anterior part of the cell. Pseudopodia and strands of cytoplasm were not seen under the cell or behind the posterior end of the moving cell. When the cell is moving, the anterior part of the cell slightly wobbles from side to side. Not often observed.
Remarks: Previously reported cell length is 6.5–20 µm ( Hartmann and Chagas 1910, Lemmermann 1914). The description here is well consistent with the description of Hartmann and Chagas (1910) who described it under the name Cercobodo parva , which was transferred once to Cercomastix by Lemmermann (1914). This species is similar to Cercomonas granulifera sensu Hollande, 1952 which has granules around the nucleus and is 12–15 µm long, but can be distinguished by the posterior flagellum tightly adhered to the cell body and lack of granules around the nucleus.
