Porównanie

Differs from C. saulae by the distinct nodes on the intersections of the axial and spiral ribs and the more sparsely distributed axial ribs. Most similar C. tectispira has the more densely distributed axial ribs and the presence of microornamentation on the intersections of the spiral and the axial ribs only.
