Diagnoza

Porównanie

The coils have straight flanks and a narrow ramp. Four strong spiral ribs run on the flanks. They are crossed by 10–12 axial ribs per turn. The adapical spiral rib is somewhat stronger on later coils than the others and its cusps are somewhat larger. The base is convex and not set off. The weakly thickened border spiral rib is followed by approx. 7 not thickened spiral ribs, which become somewhat weaker towards the center of the base. The specimens are similar to Rhabdocolpus muricatum (Sowerby, 1825) and R. oehlerti Cossmann, 1913.
