This small species, with linear to linear-elliptical valves, slightly inflated middle, formally described using light scanning electron microscopy. The has single H-shaped chloroplast striae usually biseriate tending be uniseriate near centre valve. valve dimensions, valve, pole central area shapes, density pattern allow their separation from similar taxa belonging genera Eolimna, Naviculadicta Sellaphora. ecological preferences are mineral waters high nitrate concentrations. examination Eolimna characteristics lead propose four combinations species.
