Descrição original:

(Breure & Ablett, 2019): “shell up to 48.5 mm, 2.0 times longer than wide, narrowly rimate with rather flat sides, elongated, solid. Colour whitish-yellowish typically with two interrupted spiral colour bands on the last whorl above the periphery, crossing weaker axial streaks of a less intense colour and forming V-like marks; one spiral band at the periphery and one below starting at the insertion of the columellar margin; with a white line below the suture and below the periphery a broader white band with the axial streaks faintly continuing. Surface somewhat shining; the upper whorls smooth, on the remaining whorls the growth striae are slightly thickened. Protoconch with a grating sculpture of axial riblets and spiral striae, which are of equal strength. Whorls 6.1, hardly convex; suture slightly impressed and bordered by a whitish to yellowish line below, ascending towards the aperture. Aperture elongate-ovate, 1.4 times longer than wide, 0.56 times the total length. Peristome thin, expanded throughout, whitish inside and outside. Columellar margin curved, reflexed, dilated above and receding. Parietal wall with a thin callus, transparent.”
