With the super-family no problem, Conoidea. In the case of Family we see on gastropod.com : Raphitomidae and on WORMS: Conidae - Raphitominae. Any ideas on this subject? Carlos Carvalho Portugal
gastropods.com is an amateur website whereas worms has a scientific board; as a consequence in the latter you can also find the references which motivate the taxonomic choices, so up to now the right family is Conidae (see here)
