Subgenus Kurodaconus Shikama & Habe, 1968

The species assigned to the (sub)genus Kurodaconus (type species: Kurodaconus stupa (Kuroda, 1956)) form a well-supported clade sister to Conus (Mitraconus) cylindraceus Broderip & Sowerby, 1830, and these two are sister to another clade which contains the type species for the (sub)genus Turriconus Shikama & Habe, 1968, namely Conus (Turriconus) excelsus G.B. Sowerby III, 1908 (see below). In addition to this, species in Kurodaconus exhibit distinct shell and radular morphologies which allow a clear separation from species in Turriconus (see Tucker & Tenorio 2013). For this reason, we hereby consider Kurodaconus a valid supraspecific taxon, rather than a synonym of Turriconus .
