Ventral margin slightly concave. Dorsal margins convex with three slight undulations in all cell cycle stages, less visible in smaller specimens (n = 30). Valve length 21.0 – 56.6 μm, valve width 5.0 – 6.8 μm. Areolae not distinguishable under LM. Striae slightly radiate, denser at the apices, spaced, 11 – 14 in 10 μm in the middle of the valve. Striae composed of continuous rows of rounded areolae, 40 – 50 areolae in 10 μm. No spines were observed. Terminal raphe fissures positioned very close to the apical valve margin extending over almost the entire apical end.	en	Ruwer, Daiane Trevisan, Blanco, Saúl, Rodrigues, Liliana (2021): Eunotia Ehrenberg (Eunotiaceae, Bacillariophyta) in a subtropical floodplain: a new species and taxonomic contributions.
