Compare

The valve margin of E. temperei is distinctly gibbous on the ventral side. In comparision, the ventral side of E. reimeri is expanded and that of E. nicafei and E. latum are linear. The valve terminations of E. reimeri are acute, while those of E. temperei are more rounded.

While there have been a number of reports of E. sinicum from North America, this species has acute apices, a finer striae count (12 in 10 μm) and finer areolae count. The density of areolae within a central, dorsal stria is 7-8 in 5 μm.
