Cafeteria minuta ( Ruinen 1938) Larsen et Patterson 1990 ( Figs 1g , 2l )

(= Pseudobodo minuta Ruinen 1938 )

Observation: Cells are 4–4.5 μm long with a small ventral groove. The cells have two flagella emerging from the anterior end of the groove. The longer anterior flagellum is 2.2–2.5 times the cell length, beats with a sine-wave, and the posterior one is slightly longer than the cell. In swimming cells, the anterior flagellum is directed forward and the posterior one trails. May attach to the substrate by the tip of the posterior flagellum. Description based on observations of two cells.

Remarks: Our observations are in agreement with the observations of Larsen and Patterson (1990). This species resembles Cafeteria roenbergensis , but can be distinguished by the longer anterior flagellum relative to the cell and because the anterior flagellum of C. roenbergensis is curved over the body when attached ( Larsen and Patterson 1990, Lee and Patterson 2000). This species has been found at marine sites in Australia, Belize, Brazil, India and Portugal ( Larsen and Patterson 1990, Ruinen 1938, Tong et al. 1998, Vørs 1993b, Lee 2001).
