Percolomonas similis Lee, Brandt, Vørs et Patterson 2003 ( Figs 1y , 4h)

Observation: Cells are oval in shape, 4–6 µm long, and laterally compressed. The cells have a groove extending ventrally in the anterior half of the body. Two flagella emerge from the head of the ventral groove. One long non-acronematic flagellum is about 2.5 times the cell length, is slightly thinner than the shorter flagellum and trails when moving. The short flagellum is slightly shorter than the cell length, usually lies in the groove and may beat fast in the groove. The cells move by skidding or gliding. Description based on observations of nine cells.

Remarks: Our observations are in agreement with the observations of Lee et al. (2003). The species of the genus Percolomonas are reported with four flagella except P. denhami Tong 1997 which has three flagella. This species is similar to P. denhami in cell shape and length, but can be distinguished by the number of flagella. It has been reported from several marine sites in Australia and in Korea under the name Percolomonas sp. with lengths of 5–7 µm ( Lee 2001, 2002; Lee et al. 2003).
