Description
The height of the shell attains 30 mm, its diameter 18 mm.
(Original description in Latin) This smooth, perforate, sinistral shell is ovate-conical. It is yellowish, featuring two purplish-chestnut bands on the lower portion. The spire is conical with a somewhat blunt apex. It comprises 5.5 slightly convex whorls, with the body whorl extending along the spire's axis. Submedian and basal bands continue into the aperture. The columella is slightly twisted. The aperture is oblique, obliquely ovate, and the peristome is flattened-reflexed, livid purple, becoming livid brown posteriorly. The margins are barely connected by a whitish callus. The columella is whitish, with a short dilation at the upper end.
