Description:

Abollifer prolabens Voers, 1992. The cell is about 8-12 x 10-20 microns It is ovoid-oval and dorso-ventrally flattened with a deep anterior or depression into which the flagellum inserts. The sides of this depression are swollen. The cell surface is rigid and granulated, the cell appears opaque and probably has a pellicle. The cell moves by gliding, but it may detach from the substrate and jerk through the water with an irregular sinusoidal flagellar beat, a second shorter trailing flagellum is sometimes present.
