Genus Profundiconus Kuroda, 1956 (Gastropoda, Conoidea): Morphological and molecular studies, with the description of five new species from the Solomon Islands and New Caledonia

The genus <em>Profundiconus</em> Kuroda, 1956 is reviewed. The morphological characters of the shell, radular tooth and internal anatomy of species in <em>Profundiconus</em> are discussed. In particular, we studied <em>Profundiconus</em> material collected by dredging in deep water during different scientific campaigns carried out in the Solomon Islands, Madagascar, Papua New Guinea and New Caledonia. We reconstructed a phylogeny of 55 individuals based on partial mitochondrial <em>cox1</em> gene sequences. The phylogeny shows several clades containing individuals that do not match any of the known species of <em>Profundiconus</em> based on their shell and radular morphologies, and are introduced here as five new species: <em>Profundiconus maribelae</em> sp. nov. from the Solomon Islands; <em>P. virginiae</em> sp. nov. from Chesterfield Plateau (New Caledonia); <em>P. barazeri</em> sp. nov. from Chesterfield Plateau and the Grand Passage area (New Caledonia); <em>P. puillandrei</em> sp. nov. from Norfolk Ridge (New Caledonia), Kermadec Ridge (New Zealand) and possibly Balut Island (Philippines); and <em>P. neocaledonicus</em> sp. nov. from New Caledonia. Furthermore, <em>Profundiconus teramachii</em> forma <em>neotorquatus</em> (da Motta, 1984) is raised to specific status as <em>P. neotorquatus</em> (da Motta, 1984).
