External views (A, B); internal views (C-H): A, complete frustule (note the slit-like areole on valve face and mantle); B, hypovalve (left) with footpole immersed in the six girdle bands, which appear totally hyaline; they are alternately open and closed at each pole; C, valve with apposed valvocopula and a further copula; D, headpole; the valvocopula forms a septum; the valve pseudoseptum is thus mostly covered, only a triangle remains visible; E, valve footpole with pseudoseptum and open valvocopula (no further copula); F, exposed fracture of the right valve margin: the transapical ribs and the alveoli covered by hymenes become visible; G, exposed fracture at the pseudoseptum; H, the corroded hymenes allow a view of the areolae which are more numerous and differently shaped than the slit-like external foramina.
