Taxonomic remarks and comparisons.

This species is recognised based on the descriptions and figures in Houart (1992) and Merle et al. (2011), specifically in having a rounded last whorl usually associated with three spineless varices, each with a short and webbed expansion on adapical section, an aperture with a characteristically small callus with straight, adherent columellar lip, and a broad siphonal canal. See also comprehensive taxonomic remarks in Houart (1992).
