| T. A. Neubauer et al. 2013 | Broad trochiform shell with up to seven whorls. Dimensions usually range around 6 mm in height (max. 7.5 mm) and 3 mm in width (max. 4 mm). The protoconch is high trochiform with weakly immersed initial part and comprises c. 1 whorl with strongly granular surface sculpture. It is not clearly separated from the teleoconch. Whorls soon expose a stepped outline with flanks parallel to the axis, a narrow sutural ramp and weakly incised sutures. In most specimens, two keels are formed of which the strongest appears near the upper suture, forming the border between flank and sutural ramp. The second one is formed close to the lower suture. The keels range from weak to prominent, from thin blade-like flanges to broad bulges. In addition, the whorls bear faint spiral grooves. In some individuals, the sculpture is strongly reduced to sutural ramp and spiral lines, without keels. The detachment of the whorls already starts soon resulting in a stronger inclined growth direction of the last whorl, which attains about half of shell height. A distinct angulation appears between the whorl and the rather straight base. The aperture is small and ovoid to subcircular. As it is always detached from the base, it forms a wide umbilicus. The lips have sharp terminations and are almost parallel in lateral view; sometimes, a weak posterior indentation occurs. |
