Suiadifflugia multipora Green, 1975

Diagnosis: The test is sub-spherical, constructed of minute mineral particles of varying size. The aperture is complex, consisting of a central pore and 8 to 11 irregularly elongate oval pores radiating around the central pore like the petals of a flower. Some of the preserved specimens had pseudopodia emerging from the central pore and several of the radial pores. The region around the central pore is constructed of smaller particles than the rest of the test. When the apertural region is viewed obliquely the arches between the pores are seen to be raised above the surface of the sphere. Each arch is composed of several layers of particles. In the scanning electron micrographs the particles appear somewhat smoothed, but under the light microscope the particles appear to be more angular (from Green, 1975).

Dimensions: Diameter 178 to 192 µm, heights 178 to 201 µm.

Ecology: freshwater, sediments; North-America.
