الوصف:

Anisonema pusillum Stokes, 1886. Cells are spindle-shaped, rigid and 11 microns long. Dorsally convex and ventrally concave. The anterior flagellum is about the cell length and the posterior one is about 3 times the cell length. Although initially assigned to the genus Anisonema, it seems improbable that this assignment is correct.
