Length Range: 15-19 µm
Width Range: 2.4-2.6 µm
Striae in 10 µm: 23-24 in the center valve, 24-25 at the ends
Eunotia enischna valves are small and slender. The ventral margin is concave, and the dorsal margin is convex. The apices are defined by a marked change in slope on the dorsal margin. The apices are capitate, rounded, and dorsally recurved. The raphe is short and curves on to the valve face. Striae are indistinct and radiate. The areolae are unresolved in the LM.

Valves slender, concave on the ventral margin, convex on the dorsal margin, with apices defined by a marked change in slope on the dorsal margin, 15 – 19 μm long, 2.4 – 2.6 μm wide. Apices capitate, rounded, dorsally recurved. Helictoglossae not visible in the light microscope. Rimoportula at one end of valve. Raphe short, curved on to valve face. Striae indistinct, radiate, 23 – 24 in 10 μm at the center of the valve, 24 – 25 in 10 μm near the ends. Puncta unresolved in the LM.
