Aperture is slightly oblique, semiovate or piriform, obstructed by 3 teeth: in the middle of the parietal wall, on the columella, and a smaller one in the palate (frequently wanting). Peristome is spreading, slightly labiate, the margins joined by a callus, the right margin very strongly curved above, columellar margin is somewhat dilated, spreading.[5]

The width of the adult shell is about 2.5 mm, the height about 1.5 mm.[5]
