Sellaphora hustedtii has smaller valves and fewer striae around the central area. S. santiagoi is extremely similar to S. subfasciata; further investigation may show the two taxa to be conspecific. The only difference between two species is the areola density: 56-64 in 10 µm in S. subfasciata and 70 in 10 µm in S. santiagoi.
