SEM images taken from the holotype material (BR-4711, Rabenhorst sample 1441, Casaccio, Switzerland). 69–71. Three external views of an entire valve. Note the presence of the irregular marginal spines and the rather well-developed apical pore field at each apex. The virgae and sternum are clearly raised with the striae as punch-holes. 72. External view of the open valvocopula showing fimbriae. 73. SEM internal view of an entire valve. Scale bars = 10 µm.
