Diagnoza

Porównanie

Similar to Conusella conica Gründel, 1999 from the Pliensbachian of Germany but this latter differs only in having a slightly more slender shell, the protoconch whorls broadening more rapidly, and in opisthocyrt growth lines on the teleoconch flanks. Conusella? sp. sensu Gründel (2003), from the Callovian of north-eastern Germany has strongly convex whorls and a deep suture. The shell is also very similar to Jurassic Zebina laevis (Sowerby, 1829) and Zebina gymnoides (Hudleston, 1892) but first differs in having a more ovate shell shape and the latter has more slender shell.
