  2. Dorsal margin convex
  3. Apices capitate
  4. Striae indistinct, radiate
  5. Raphe short

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 striae of E. enischna are radiate and very faint, even though the striae density is not high. The aerolae can not be resolved in the LM. The raphe is short and curves on to the valve face.
