Diagnoza Thin discoidal conch with acute venter; pointed tips of all lobes and saddles of the suture, the middle flank lobe being the deepest. Porównanie The only specimen from Kowala has been already illustrated by Schindewolf (1944, 1959; as Discoclymenia kayseri) and Becker (2002). Stratigraphic distribution of other members of the group (classified by him in Alpinites) suggest that this was a lineage evolving towards more and more oxyconic conch.
