Compare
Eunotia areniverma is similar in shape to E. metamonodon, but the apices of E. areniverma are more rounded. Eunotia monodontiforma possesses spines on the dorsal margin and a greater areola density. Eunotia maior has spines on the apical, dorsal, and ventral margins. Eunotia formica is smaller and more narrow, with a lower stria and areola density than E. metamonodon. Eunotia indica is smaller and has a greater stria and areola density.
