Rhogostoma micra Cavalier-Smith and Scoble, 2011

 

Diagnosis: Morphology as R. minus. Test more often associated with debris and bacteria. Behavior very similar, but pseudopodia more often, but not restricted to, trailing and leading bifurcating strands extruded from beneath the cell; cells can be less regular in shape than in R. minus. Finger-like pseudopodia more frequently exhibited, and lamellar pseudopodia less frequent, than in R. minus; when traveling, cell occasionally tilts to point cleft in direction of travel, perhaps to facilitate or as a result of extension of leading pseudopodia for locomotion-cells then appear slightly narrowed at the aperture end (light-bulb-shaped). Division by binary fission.

 

Dimensions: cell size: 7.5 µm (6.5-10 µm).

 

Ecology: Freshwater.
