Fragilariforma meireana Van de Vijver & D. M. Williams, sp. nov., LM micrographs taken from the holotype material (BR- 4867, Damme, Belgium) A – N LM pictures of valves in valve face view in decreasing length. The white arrows indicate the rimoportulae. The black arrows indicate anomalies in the striation pattern O – Q LM pictures of three frustules showing internal cells. Scale bars: 10 µm.	Figure 1.

Fragilariforma meireana Van de Vijver & D. M. Williams, sp. nov., SEM micrographs taken from the holotype material (BR- 4867, Damme, Belgium) A SEM external view of an entire valve B, C SEM external detail of two valve apices showing the rimoportulae (white arrows) and the apical pore field. Note the rudimentary spines and the irregular striation pattern on C. D SEM internal detail of a valve apex showing the rimoportula (white arrow) E SEM internal view of an entire valve. The rimoportulae are indicated with white arrows. F SEM view of the broad valvocopula. Scale bars: 10 µm (A, E – F); 1 µm (B – D).	Figure 2. Fragilariforma meireana Van de Vijver & D. M.

Fragilariforma meireana Van de Vijver & D. M. Williams, sp. nov., SEM micrographs taken from the holotype material (BR- 4867, Damme, Belgium) A SEM view of a complete frustule with the internal cell inserted between the valves B SEM view of the resting spore covered by the valvocopula. At the apices, the valvocopula is well visible. Occasionally, very shallow ridge present on the plain side visible as a thin line. C SEM external detail of the valve apex with the valve, internal cell and one detached copula D SEM external side view of the internal cell. Note the ridges on the top E SEM external valve face view of the internal cell surrounded by the valvocopula. Scale bars: 10 µm (A, B); 1 µm (C – E).	Figure 3.
