Californiconus is a genus of sea snails, marine gastropod mollusks. The experts at WoRMS place this group of species in the family Conidae, the cone snails, but some other experts placed previously the genus in a proposed family, the Conilithidae. This is a monotypic genus.
Use of this genus in the binomial name of this species was, until 2015, treated by the experts at WoRMS as an "alternative representation" of the species. (When the "alternative representation" was not used, this species was still placed in the Linnaean genus Conus.)
In 2015 Puillandre et al. placed Conus californicus as the sole member of its own genus as Californiconus californicus This species has always been considered a species with unique characteristics within Conidae, because it shows diverging molecular (including toxicological) and morphological characteristics. Its generalist diet includes fish, other molluscs and worms, contrary to what is the case in other cone snail species, which have more specialized diets.
The Tucker & Tenorio taxonomy distinguishes Californiconus from Conus in the following ways:
This list of species is based on the information in the World Register of Marine Species (WoRMS) list. Species within the genus Californiconus include only:
Prior to 2009, all cone species were placed within the family Conidae and were placed in one genus, Conus. In 2009 however, J.K. Tucker and M.J. Tenorio proposed a classification system for the over 600 recognized species that were in the family. Their classification proposed 3 distinct families and 82 genera for the living species of cone snails, including the family Conilithidae. This classification was based upon shell morphology, radular differences, anatomy, physiology, cladistics, with comparisons to molecular (DNA) studies. Published accounts of genera within the Conidae (or Conilithidae) that include the genus Californiconus include J.K. Tucker & M.J. Tenorio (2009), and Bouchet et al. (2011).
