Description. The shell is cap-shaped (LS is 2.37

mm; HS is 0.86 mm; WS is 1.8 mm, WS/LS is

0.76), not high (flattened). The shell walls are slightly convex and thick. The apex is slightly shifted to the anterior end of the shell (the distance from the anterior edge is 1.4 mm). The aperture is oval, the edges are smoothed. The surface of the shell is uneven, rough with a carbonate crust.
