(Original description in Latin) The sinistral shell is elongate-conical. It exhibits a smooth and very glossy surface with a yellowish-white base color. It is painted with seriate brown spots and two to five brown bands at the base, and features a pale apex. Comprising six somewhat flat whorls, the shell possesses an ovate aperture that occupies three-sevenths of its length. The peristome appears somewhat thick, white, and expanded, lacking a parietal callus. The columellar margin is thin, rectilinear, and somewhat vertical, forming a distinct angle with the basal margin and being plainly adnate above.
