Remarks.
The morphology of this species is similar to the smallest specimens of
Retrotapes exalbidus
.
Zelaya (2009b)
showed that they can be differentiated in that
Tawera elliptica
has wider cords and finer interspaces and the inside of the shell is either purplish or brownish. All specimens collected during this study had a strong violet coloring on the inside of the valves.
