Compare
Surirella cruciata should be compared to S. bidentata, described from moss habitats in Chile. Both species are similar in valve outline and the unique elevation of central portion of the valve. However, S. bidentata is more isopolar, has a greater valve width (60–70 μm) and has a lower density of alar canals (9–11 in 100 μm) compared to S. cruciata.
