Cafeteria roenbergensis Fenchel et Patterson 1988

( Figs 1h , 2g )

Observation: Cells are D-shaped, 3–5 μm long, laterally compressed, and have a shallow groove on the ventral side of the cell. Two flagella of similar length emerge subapically and are slightly longer than the cell. In attached cells, the anterior flagellum is directed perpendicular to the ventral face of the cell and the posterior one is reflexed, passing over one face of the cell and then attaching to the substrate by the tip. The anterior flagellum is directed forwards and beats with a sine wave, and the posterior flagellum is directed backwards and trails when swimming. Move fast following a spiral path. Description based on observations of nine cells.

Remarks: Generally, our observations are consistent with the descriptions of Fenchel and Patterson (1988) and Larsen and Patterson (1990). This genus consists of four species: C. roenbergensis Fenchel et Patterson 1998 , C. ligulifera Larsen et Patterson 1990 , C. marsupialis Larsen et Patterson 1990 , C. minuta ( Ruinen 1938) Larsen et Patterson 1990 . Cafeteria roenbergensis resembles C. marsupialis in general appearence and in having a short anterior flagellum, but C. marsupialis has a more conspicous ventral groove and is larger. Cafeteria roenbergensis has a widespread distribution ( Lee and Patterson 1998, 2000; Al-Qassab et al. 2002; Lee 2002b; Lee et al. 2003; Lee 2007a).
