Diagnosis

|---|---|---|
| M. Harzhauser and T. Kowalke 2002 | The stout, medium-sized, juvenile shell consists of six flattened whorls and measures 1.8 mm in height and 1 mm in width. A fragment of an adult shell indicates a size of up to 10 mm in height and 6 mm in width of fully grown specimens. The protoconch comprises two rounded whorls, which appear to be smooth. It measures 0.2 mm in height and 0.23 mm in maximum dimneter. The first whorl measures 0.05-0,06 mm in the width of the initial cap and 0.15-0.16 mm in maximum diameter. The transition to the teleoconch is indicated by a strong sinusigera notch, which extends over 0.12 mm. The sinusigera is thickened in its adapical portion and thin and broken off in its abapical portion. The teleoconch whorls are characterised by two rows of widely spaced nodes close to the sutures. These nodes are the blunt terminations of very weak axial ribs. The surface is covered by fine spiral grooves. |
