[edit] Shell description
The shell is small, thin, white, and depressed-globose. The umbilicus is deep, but very narrow, which is unusual in such a broad shell. The surface is smooth, except for a sharp thread bordering the umbilicus, and regular axial growth lines, developed only over the lower part of the base. The aperture is ovate-lunate, and the peristome is thin-edged and discontinuous.
The shell height is up to 0.63 mm, and the width is up to 0.9 mm.
