(Ehrenberg)
Solenosphaera zanguebarica group?
General outline of shell often subtriangular, the vertices extending into 3-4 short tube-like protrusions with perforated walls and open ends. The rim of these tubes may bear spines. Pores irregular in shape and size, but generally roundish or subangular. Shell diameter: 100-150 µm.
A morphotype very similar to Solenosphaera zanguebarica (and most probably conspecific with it), usually cited as Disolenia quadrata (Ehrenberg) (S. zanguebarica group?), differs by having somewhat larger tubes which are better differentiated from the main body of the shell.
