Strombidium dalum Lynn, Montagnes & Small 1988

Lynn & Gilron (1993) reported a ciliate from Jamaica which they considered to be Strombidium dalum based on the size of the cell, the number of oral polykinetids and the position and shape of the macronucleus (Fig 8). However, this ciliate may be a new species, since it was found in tropical waters and does not show the torch-like shape of the cilia of the APZ which is a characteristic feature for S. dalum. Therefore, we only include the original description in this data sheet.

Cell conical; in protargol stains the cilia of the APZ form a long, spiralled, ?torch-like? shape; APZ distinctly separated from VPZ; girdle kinety equatorial; one macronucleus, conical or spherical, mostly at the posterior end; numerous prominent trichites

Temperature: 5-20 ºC Salinity: 26-36?

Cell conical, 15 (10-20) µm long and 10 (5-15) µm wide; prominent trichites, insert anterior to the girdle and extend posteriorly and internally (Fig 1,7). Shallow oral cavity; APZ distinctly separated from VPZ; long, spiralled, ?torch-like? cilia of the APZ (Fig 1,6). Girdle kinety equatorial, completely surrounding the cell (Fig 1,6). One macronucleus, conical or spherical, at the posterior end (Fig 1,6,7).
