Colour whitish, with dark- to reddish-brown axial zigzag streaks, with unevenly spaced white dots; the white spaces in between 1–5 times as wide as the streaks. Upper whorls whitish, the colour pattern disappearing.

Surface hardly shining, smooth. Protoconch with a grating sculpture of axial riblets and spiral striae, which are of equal strength. Whorls 5.2, slightly convex; suture slightly impressed and bordered by a thin, whitish line below, ascending just before the aperture. Aperture elongate-ovate, 1.47 times longer than wide, 0.56 times the total length. Peristome thin, expanded throughout, white with a reddish- to dark brown border inside. Columellar margin curved, reflexed, dilated above and receding. Parietal wall with a thin, transparent callus, with a dark brown hue”
