Descrição original:

(Grego, Šteffek & Infante, 2007): “Shell dextral, milky white, with a yellowish periostracum, which is present at only a few places; measuring 33.7 mm in height and 6.3 mm in width, with 11 tapering teleoconch whorls. The protoconch whorls and the initial 7 teleoconch whorls are rather convex, whereas the final four 4 are more flat.

The entire surface is sculptured with close, very fine, evenly spaced striae. Aperture subtetragonal; the columellar margin sinuous, angled, with a distinctly curved, and callous fold; the fragile outer lip is slightly curved downward.

The basal apertural margin is fragile; it is almost vertically connected to the outer lip. Columella spirally ascending, coiling around a very small central cavity and forming a kind of small pseudoumbilicus. The apertural callosity and the peripheral keel are not fully developed in the holotype, which might be subadult or slightly damaged.”
