) have recently illustrated numerous specimens, the intraspecific variation of this species remains unclear due to its general scarcity. Based on their illustrations and unpublished material, there seems to be scope for further differentiation. Both morphotypes A and B have a posterior process and hence a tapered posterior margin of the basal cavity. However, some of our specimens do not develop a posterior process and have a rounded posterior margin at the basal cavity. Tose are here assigned to a different species, which for now is kept in open nomenclature (
