Morphology
External polykinetid zone composed of 24-30 polykinetids, 9-11 ciliated somatic kineties, C-shaped macronucleus (Lynn & Montagnes 1988b)
Other remarks
It is better to study it with the help of the protargol method (Montagne & Lynn 1987). This species was referred to the genus Rimostrombidium by Petz & Foissner (1992)
Life form
Solitary
Size
Cell length 40-70 µm, width 40-60 µm
