Diploneis submarginestriata is very similar in shape, but differs in width (6.2-7.4 µm) and stria density (18-20 in 10 µm). Diploneis marginestriata is also similar, and is distinguished by wider valves (8–11 μm) and a lower stria density (17–18). The longitudinal canal of D. marginestriata also is slightly wider.
