Description
The height of the shell attains 6.5 mm (0.26 in), its greatest diameter 10 mm (0.39 in).[citation needed]
(Original description in Latin) The shell has a conoid-depressed shape and is rather thin, showing serial hairs. It is reddish with a blackish covering. The spire is short and conical. There are 5 moderately convex whorls, with the body whorl rounded at the periphery and a shiny, broad, somewhat circumscribed callus at the base. The aperture is nearly diagonal and semi-oval. The columella is somewhat compressed, ending forward in a small denticle. The peristome is scarcely expanded, with the basal margin very slightly arched, forming a small sinus with the columellar tooth. The operculum is thin and pearly.[2]
