Shell with the shape of a truncate cone, fragile, with a very evident peripheral keel. Protoconch hyperstrophic of about 1,75 smooth whorls, and of about 380 µm diameter. Teleoconch of about 1,25-1,5 whorls, increasing rapidly; there are three spiral nodulous cords: one of them forms a peripheral keel; another is in the upper part of the spire between the peripheral one and the suture, and the third rounding the umbilical infundibulum. At the end of the spire, a new cord begins between the two upper ones. The surface has numerous fine curved prosocline threads that continue into the umbilicus, and under magnification, fine spiral rows of microtubercles appear between the ribs. The umbilicus is wide showing the previous whorls. Aperture ovoid-rounded with the upper part of the outer lip sharp and extended dorsally. Dimensions: Holotype is 2.0 mm maximum dimension (diameter).

There is no other species in the genus with this characteristic shell morphology, with many axial threads and especially the single dorsal prominent cord which produces an important angulation.

Distribution: In the original description, this species was known only from Liberia. We extend its range from Mauritania to Ghana and Angola.
