Very evolute compressed shell by flattened sides; from sub-quadrate to sub-rectangular whorl section. No whorls overlap occurs. The shell shows also a slow-growth coiling. Tricarinate-bisulcate and moderately wide venter with a thin keel. The sulci are little deep. The low umbilical wall is gently sloped and the umbilical edge is rounded. The sparse, fine, single, falcoid and rursiradiate ribs are projected on the ventrolateral edge and they show a short proximal segment moderately angled backward. The ammonitic suture is very simple and little frilled.

Very evolute compressed shell showing from sub-quadrate to sub-rectangular whorl section without overlap of the whorls and flattened sides. The moderately wide venter is tricarinate-bisulcate with little deep sulci and a thin keel. The umbilical wall is low and sloped in the phragmocone, higher and angled in the body chamber. The umbilical edge is gently rounded. The ribs are spaced with a moderately rib-density (we count 54 ribs in the last phragmocone whorl), fine, single and rursiradiate with falcoid appearance. They show a short proximal segment gently angled backward and they are moderately projected on the ventro-lateral edge. The suture is simple, little frilled, with a developed L lobe and a wide E lobe shorter than L. The U
