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

[摘要] The problematic conoidean genusRaphitomas.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 obesan.sp. andR. maculosan.sp. are described as new, and anotherRaphitoma aequalis(Jeffreys, 1867) is reported from Norway for the first time. The taxonomic and nomenclatural status ofR. reticulata(sensu Jeffreys 1867) andR. asperrima  (sensu Forbes & Hanley 1853) are discussed. Empty shells of several additional species indicate that the number ofRaphitoma -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.
