Discocelis punctata Larsen and Patterson 1990
No full textDiscocelis punctata Larsen and Patterson, 1990 (fi gures 23l -m, 24g) Description. Cell about 6 Mm long, disc-shaped, dorso-ventrally fl attened, anteriorly concave and posteriorly convex. Two fl agella emerge from a depression on the anterior end of the cell. The recurrent fl agellum trails behind the gliding cell and is slightly longer than the cell. The shorter fl agellum is less than 1 Mm long, is hard to see and is inactive. The nucleus is located anteriorly in the right half of the cell. There is a line of bodies around the margin of the cell. Glides smoothly in closely contact with the substratum. Rare. One cell observed. Remarks. Discocelis punctata has been described by Larsen and Patterson (1990) and Tong et al. (1998) from marine sites in Brazil and Fiji, and our observations are in accord with their description except our cell is smaller than the previously reported cell dimensions of 6.5-9 Mm. The size of the cell observed here is between that of D. saleuta and D. punctata. Discocelis saleuta may have peripheral bodies (Vørs, 1988; Larsen and Patterson, 1990) but these are not visible by light microscopy. We assign this individual to D. punctata because the peripheral granules were easy to see. Future work may indicate that we need to combine these two species. This species can be confused with the genus Metromonas in having one long recurrent fl agellum and one short, inactive fl agellum, but it is distinguished by the fl atness of the cell, the pattern of movement, and the peripheral bodies.Published as part of Lee, Won Je & Patterson, David J., 2000, Heterotrophic flagellates (Protista) from marine sediments of Botany Bay, Australia, pp. 483-562 in Journal of Natural History 34 on pages 550-55
Cafeteria roenbergensis Fenchel and Patterson 1988
No full textCafeteria roenbergensis Fenchel and Patterson, 1988 (fi gures 20g, 21d, e) Description. Cells are D-shaped, 3.5-5 Mm long, and laterally compressed. There is a shallow groove on the left side of the cell. Two fl agella of similar length emerge subapically and are slightly longer than the cell. The anterior fl agellum is directed perpendicular to the ventral face of the cell of attached cells. The posterior fl agellum is reflexed, passing over one face of the cell and then attaching to the substratum by the tip. In swimming cells, the anterior fl agellum is directed forwards and beats with a sine-wave, and the posterior fl agellum is directed backwards and trails. Usually moves fast following a spiral path, but sometimes moves slowly. Food particles (bacteria) may be ingested near the posterior part of the ventral groove. Not common. Remarks. Generally, our observations are consistent with descriptions of Fenchel and Patterson (1988) and Larsen and Patterson (1990). Previous studies reported the size range to be 1.5-10 Mm (Fenchel and Patterson, 1988; Larsen and Patterson, 1990; Vørs, 1992a, 1992b, 1993a, 1993b; Patterson et al., 1993; Vørs et al., 1995; Ekebom et al., 1996; Patterson and Simpson, 1996; Tong, 1997 a, 1997b; Tong et al., 1997, 1998; Bernard et al., 1999). This species has been widely found from marine sites in Antarctica, subtropical and tropical Australia, North Atlantic, Baltic, Denmark, England, Gulf of Finland, Greenland and equatorial Paci fi c. This species resembles Cafeteria minuta (Ruinen, 1938) Larsen and Patterson, 1990 in general appearance, but is distinguished because C. minuta has a longer anterior fl agellum. Cafeteria roenbergensis resembles C. marsupialis Larsen and Patterson, 1990 in general appearance and in having a short anterior fl agellum, but C. marsupialis is larger and has a ventral groove with a posterior channel leading into the cell. It may not be clearly distinguished from Acronema sippewissettensis (Teal et al., 1998), the fl agella of which are said to be acronematic. Cafeteria roenbergensis may occasionally occupy about 6-20% of the heterotrophic fl agellate population (Fenchel, 1982; Tong, 1997b) and is cosmopolitan.Published as part of Lee, Won Je & Patterson, David J., 2000, Heterotrophic flagellates (Protista) from marine sediments of Botany Bay, Australia, pp. 483-562 in Journal of Natural History 34 on page 53

Petalomonas minor Larsen and Patterson 1990
No full textPetalomonas minor Larsen and Patterson, 1990 (fi gures 14d, 16a -d) Description. Cell outline ovate-rhomboid, 6-11 Mm long, 4-8 Mm wide. A distinct, longitudinal dorsal keel lies to the right of the midline. Two fi ne ventral ridges may be seen towards the posterior end. The dorsal face is slightly concave between the longitudinal dorsal keel and the lateral margin of the cell. With one fl agellum about the same length as the cell inserting in a reservoir located in the right side of the cell. The nucleus is in the left side. Glides with the fl agellum directed forwards. Commonly observed. Descriptions based on observations of 28 cells. Remarks. Larsen and Patterson (1990) fi rst described this species from marine sites in tropical Australia and Fiji. They reported lengths ranging from 7 to 9 Mm. Generally, our observations are in accordance with observations of Larsen and Patterson (1990), but the species described here has two fi ne ventral ridges not reported by Larsen and Patterson (1990). They could easily have been overlooked. The species resembles P. poosilla (see below) in having two fi ne ventral ridges and in length, but it can be distinguished by its dorsal keel and cell shape. In having one distinct dorsal keel, the species is similar to a few other species in the genus Petalomonas such as P. lata Christen, 1962, P. steinii Klebs, 1893 and P. variablilis Christen, 1962 (see Huber-Pestalozzi, 1955; Christen, 1962b). It can be recognized from all of these by its small size.Published as part of Lee, Won Je & Patterson, David J., 2000, Heterotrophic flagellates (Protista) from marine sediments of Botany Bay, Australia, pp. 483-562 in Journal of Natural History 34 on page 52
Ploeotia corrugata Larsen and Patterson 1990
No full textPloeotia corrugata Larsen and Patterson, 1990 (fi gures 17a, 18a -d) Description. Cell measuring 8-20 Mm long (mostly 13-15 Mm) and 6-12 Mm wide. Cell outline elliptical to rhomboid, dorsally convex and ventrally fl attened. Seven ridges on the dorsal side; two of which appear as a marginal rim. The right half of the cell is slightly thicker than the left, with a slight ridge down the middle of the ventral side against which the recurrent fl agellum lies. The posterior end of the cell is indented. With two fl agella of unequal length; the anterior fl agellum is about the same length as the cell, beats rapidly from side to side with an irregular wave motion when the cell glides. The posterior fl agellum is about 1.5-2.2 times the length of the cell and tapers slightly towards the posterior end of the cell. The reservoir is on the left ventral side of the cell and the ingestion organelle with two rods extends from right anterior of cell to left posterior. Moves by smooth gliding. Common, description based on observations of 15 cells. Remarks. This species was fi rst described by Larsen and Patterson (1990) from subtropical and tropical Australia, North Atlantic, Brazil, Danish Wadden Sea, Denmark, England, Fiji, Hawaii, Panama and has also been reported from the USA, and previous reported cell length ranges from 7 to 15 Mm (Larsen and Patterson, 1990; Patterson et al., 1993; Farmer and Triemer, 1994; Ekebom et al., 1996; Patterson and Simpson, 1996; Tong et al., 1998). It is widespread and often common, but not in the winter season. The cells described here are generally in agreement with the observations of Ekebom et al. (1996) and of Farmer and Triemer (1994) under the name Lentomonas applanatum (basionym Entosiphon applanatum Preisig, 1979). We suspect that L. applanatum is synonymous with P. corrugata (Ekebom et al., 1996) because the size ranges of the two species overlap; L. applanatum, about 10 Mm, P. corrugata, 7-15 Mm, and both species have seven ridges on the dorsal side of the cell. However, the species cannot be synonymized until the uncertainty with respect to protrusion of the ingestion apparatus of L. applanatum sensu Farmer and Triemer is clari fi ed. Ploeotia corrugata resembles P. decipiens Larsen and Patterson, 1990 in general appearance, but it is distinguished by the number and prominence of the dorsal ridges, slightly smaller size and indented posterior end.Published as part of Lee, Won Je & Patterson, David J., 2000, Heterotrophic flagellates (Protista) from marine sediments of Botany Bay, Australia, pp. 483-562 in Journal of Natural History 34 on page 52
Dinema validum Larsen and Patterson 1990
No full textDinema validum Larsen and Patterson, 1990 (fi gures 3d, 5h, i) Description. Cell outline oblong to ovate, 32-53 Mm long, 22-27 Mm wide, with slightly thickened pellicle. About 16 wide longitudinal striations occur on both faces of the cell and slightly follow a S-helix. Dorsal striations are more distinct than ventral ones. The anterior fl agellum is as long as the cell and beats with a sweeping motion. The posterior fl agellum is approximately 3 times the cell length, is thicker than the anterior fl agellum and emerges as a hook from the fl agellar pocket which is in the left-hand side of the cell. The ingestion apparatus has two rods but may be di ffi cult to see. It extends halfway down the cell. This species consumed diatoms as long as 16 Mm. The nucleus is usually in the right posterior end of the cell but may be in the left-hand side. Moves by gliding and may undergo squirming movements. When changing direction, cells jerk backwards and then continue to move forward. Three cells observed. Remarks. This species was previously reported from marine sites in subtropical and tropical Australia, Brazil and Fiji, with reported cell lengths from 26 to 38 Mm (Larsen and Patterson, 1990; Ekebom et al., 1996; Patterson and Simpson, 1996). Although one of our cells was slightly pointed at both ends and the ingestion apparatus was hard to see, and was very much larger than the previously reported sizes, we assigned the cell to D. validum because of slightly thickened pellicle, hooked posterior fl agellum and squirming movements. One cell observed had its nucleus in the left-hand side of the cell, thus we suspect that the position of a nucleus is not a good diagnostic character. This species is distinguished from other species of the genus Dinema by its wide pellicular striations and the thickness of the recurrent fl agellum; it is distinguished from D. litorale Skuja, 1939 by the smaller number of pellicular striations.Published as part of Lee, Won Je & Patterson, David J., 2000, Heterotrophic flagellates (Protista) from marine sediments of Botany Bay, Australia, pp. 483-562 in Journal of Natural History 34 on page 49
Protaspis tegere Larsen and Patterson 1990
No full textProtaspis tegere Larsen and Patterson, 1990 (fi gures 22k, 25a -d) Description. Cell oblong, ovate or obovate, slightly fl attened, 14-25 Mm long and 8-14 Mm wide. The ratio of length to width is 1 to 0.7. In some cells the cell surface is warty. A longitudinal median ventral groove extends from the site of fl agellar insertion to the posterior end of the cell. Two fl agella, unequal in length; the anterior fl agellum inserts subapically in the slight depression and is as long as the cell. The posterior fl agellum inserts posterior to the anterior fl agellum and is about 1.5-2.5 times the cell length. The large nucleus is disc-shaped with anterior caps and is located anteriorly on the right-hand side or near the midline of the cell. Pseudopodia may be produced from the groove. Moves by gliding. Sometimes common. Description based on observations of 32 cells. Remarks. Cells described here are in agreement with the original description by Larsen and Patterson (1990) although we have extended the size range from the previously reported 14-20 Mm. This species has been reported from marine sites in subtropical and tropical Australia, Fiji and Hawaii (Larsen and Patterson, 1990; Ekebom et al., 1996; Tong et al., 1998). Protaspis tegere resembles P. glans in general appearance but is distinguished by the nuclear caps in P. tegere (Larsen and Patterson, 1990) and by the position of nucleus. The position of the nucleus in Protaspis metarhiza Skuja, 1939 may change with the age of cells (Skuja, 1939) and this may also be in the case of P. glans (Larsen, 1985b). Assuming that nuclear caps in P. glans have been overlooked in previous studies, P. tegere may prove to be a junior synonym of P. glans because they are distinguished only by the nuclear caps. Tong et al. (1998) described P. tegere without nuclear caps, but in their fi gure 9r the nuclear caps are shown. We note that in respect of nuclear caps the illustration is correct and the text is in error. Protaspis major Skuja, 1939 is distinguished from P. tegere due to it being larger (24-40 Mm) with an oblique ventral groove.Published as part of Lee, Won Je & Patterson, David J., 2000, Heterotrophic flagellates (Protista) from marine sediments of Botany Bay, Australia, pp. 483-562 in Journal of Natural History 34 on page 54
