Diagnoza

Low shell, almost planispiral. Small protoconch 1, smooth. Sinistral, hyperstrophic protoconch 2 ornamented with strong, almost orthocline axial ribs and very fine spiral lirae. Terminal part of protoconch thickened. Teleoconch with orthocline growth lines, otherwise smooth.

Porównanie

Differs from S. lehmanni Bandel, 1996 in having stronger, orthocline axial ribs of the protoconch and by the presence of the ribs on the whole protoconch 2.  From S.parvula Gründel,1998 differs by the smaller number of axial ribs on the protoconch.
