Diagnosis
ReferenceDiagnosis
D. Fehse and B. Landau 2002Shell very small, relatively fragile, and spherical. Spire covered by callus, faintly visible beneath 3 vertical riblets extending upwards from the posterior terminal. Body whorl globose and rounded, about 90% of total height, with the terminals strongly produced and flattened. Dorsum evenly rounded, without a true dorsal sulcus, but a weak dorsal depression, which modifies the ribs. Dorsum completely covered by 20-22 strong, irregular ribs, with interruptions. Where the ribs cross the dorsal depression, they are usually modified; interrupted, narrowed and occasionally unaltered. Base and terminals are evenly convex. Aperture curved, slightly wider in the anterior portion. Outer lip broad, widest in mid-portion, becoming narrower towards the terminals. The lip is evenly rounded and the outer margin weakly callused. The lip bears 15-18 fine, equal teeth. Siphonal and anal canals wide and indented. Columella convex, tapering steeply inwards, bordered internally by a very weak to subobsolete carinal ridge, bearing 13-15 ribs, which continue onto the carinal ridge, where they do not become significantly stronger. The carinal ridge protrudes in the fossular region. Fossula concave, not clearly delimited from the rest of the columella.
