A taxonomic review of the Norwegian species of Raphitoma (Gastropoda: Conoidea: Raphitomidae)

Main Article Content

The problematic conoidean genus Raphitoma s.l. in inshore Norwegian waters is revised based on fresh material from all along the coast of Norway. This largely shallow water group is represented by at least six species in Norwegian waters of which two, Raphitoma obesa n.sp. and R. maculosa n.sp. are described as new, and another Raphitoma aequalis (Jeffreys, 1867) is reported from Norway for the first time. The taxonomic and nomenclatural status of R. reticulata (sensu Jeffreys 1867) and R. asperrima (sensu Forbes & Hanley 1853) are discussed. Empty shells of several additional species indicate that the number of Raphitoma-species living in the North East Atlantic will be further increased in the future. The morphological variability of each species is described if possible. Shell morphology, including microsculpture and protoconch details as deduced from LM photographs, are used for distinguishing the species. Some easily observable behaviour and soft part morphology features were found to be
promising areas for further studies.
