03ED87D7FF9CBC52FF4567ABFAADFA11.taxon	description	LM Morphology (Figs 1 – 12) The cells (Figs 9 – 12) are more or less rectangular in girdle view (6 – 11 µm broad). The valves (number of valves observed: 196) are lanceolate with obtusely rounded apices (Figs 1 – 8). The raphe is lateral near the poles and the terminal fissures are strongly hooked to the secondary side of the valve (Figs 1, 7 and 8). The proximal raphe endings are almost straight and enlarged; the central pores are inconspicuous. The distance between the proximal raphe endings decreases from the largest to the smallest individuals. The axial area is lanceolate, relatively wide (up to 4 µm), slightly asymmetric in the middle part of the valve and without a distinct central area. The striae, slightly radiate throughout, appear distinctly punctate, 12 – 14 in 10 µm in the middle part of the valve, up to 18 in l 0 µm towards the poles.	en	Cohu, René Le, Gassiole, Gilles, Coste, Michel (2014): Three new species of Cymbellales (Bacillariophyceae) from Réunion Island.

03ED87D7FF99BC58FF4562F4FBB8FA0A.taxon	description	LM Morphology (Figs 28 – 46) The valves (number of valves observed: 103) are generally dorsiventral with a clearly convex margin and a straight to weakly convex ventral margin (Figs 28 – 39). In the smallest specimens the valves are nearly symmetrical (Fig. 42 – 46). The apices, broadly rounded, are rostrate to subcapitate. The length / breadth ratio varies from 2.1 to 3.3. The axial area is very narrow and linear; the central area is absent. The raphe is filiform, slighty curved to the ventral side but with dorsally deflected proximal endings terminating in inconspicuous central pores. The striae are parallel becoming barely radiate near the poles. SEM Morphology (Figs 47 – 53) Externally, the striae are composed of 2 – 7 more or less rounded areolae, around 50 in l 0 µm (Figs 47 – 48). The central area is only marked by a slightly shorter stria on either side of the valve (Fig. 47, arrow). The raphe fissure is curved towards the ventral side with almost straight and enlarged proximal endings hardly pointed to the dorsal side (Figs 47 – 48). The terminal fissures are first dorsally bent, then are strongly hooked to the ventral side and end onto the mantle (Figs 48 – 49). Internally, the raphe slit, interrupted by a very short intermissio (Fig. 50, arrow) is straight and terminates in well developed helictoglossae (Fig. 51). The striae appear as beaded strips with rounded areolae (Fig. 50). The cingulum is distinctive. Each level is composed of two opposite bands which are closed at the poles of the valves (Figs 52 – 53); they are open near the valve centre and terminate in more or less cuneate endings (Figs 52 – 53, arrows). A row of pores is visible, probably at the junction pars interior-pars exterior (fig. 53).	en	Cohu, René Le, Gassiole, Gilles, Coste, Michel (2014): Three new species of Cymbellales (Bacillariophyceae) from Réunion Island.

03ED87D7FF97BC5BFF456523FA84F996.taxon	description	LM Morphology (Figs 54 – 63) The valves (number of valves observed: 99) are lanceolate, and weakly dorsiventral with the dorsal margin slightly more convex than the ventral margin (Figs 54 – 63). The apices are short-rostrate and broadly rounded. The axial area is narrow and linear. The raphe is filiform, slightly curved to the ventral side but with dorsally deflected proximal endings terminating in inconspicuous central pores. The striae are parallel in the middle part of the valve and then become weakly radiate. SEM Morphology (Figs 64 – 72) Externally, the raphe slit is slightly curved to the ventral side and then becomes deflected to the dorsal side with enlarged proximal endings bent to the dorsal side (Figs 64 – 66). The terminal fissures are curved towards the ventral side and terminate close to the poles in drop-like endings (Fig. 66). The central area is only distinguished dorsally by three weakly shortened striae (Fig. 66). The striae are composed of apically-elongated areolae sometimes irregular in shape (Figs 65, 66), numbering around 40 in 10 µm. Internally, the raphe fissure is interrupted by an extremely short intermissio (Fig. 67) and the distal endings terminate in well-developed helictoglossae (Fig. 68). The striae form shallow depressions in which the areolae are rounded and occluded (Fig. 69) by “ papillae ” - like structures (Krammer 2002), although they may appear apically elongated when they are partially occluded (Figs 68 – 69). The raphe (Fig. 70, arrow) seems to be of the key and slot type (Krammer, 1982). As in E. cilaosensis, each level of the cingulum is composed of two opposite bands tapering near the middle of the valve where they fit together with the other bands of a different level (Figs 71 – 72). The entire cingulum could not be observed.	en	Cohu, René Le, Gassiole, Gilles, Coste, Michel (2014): Three new species of Cymbellales (Bacillariophyceae) from Réunion Island.
