The organism has a trapezoid shape when viewed from the girdle, with a curved valve featuring a central depression. The valve is notably fasciculated, and the annulus is less distinct. The length of the organism along the apical axis ranges from 58 to 288 µm, while the width along the transapical axis falls between 32.5 and 158 µm. There are 6-9 areolae in a 10 µm span at the center and 10-13 areolae at the valve margin.
