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) ([t]S. zanguebarica group?[/t][/im]), differs by having somewhat larger tubes which are better differentiated from the main body of the shell.
