Jaspidiconus is a subgenus of sea snails, marine gastropod mollusks in the genus Conasprella, family Conidae, the cone snails and their allies.[1]
In the new classification of the family Conidae by Puillandre N., Duda T.F., Meyer C., Olivera B.M. & Bouchet P. (2015), Jaspidiconus has become a subgenus of Conasprella: Conasprella (Ximeniconus) Tucker & Tenorio, 2009 represented as Conasprella Thiele, 1929 [2]
Distinguishing characteristics
[edit]The Tucker & Tenorio 2009 taxonomy distinguishes Jaspidiconus from Conus in the following ways:[3]
- Genus Conus sensu stricto Linnaeus, 1758
- Shell characters (living and fossil species)
- The basic shell shape is conical to elongated conical, has a deep anal notch on the shoulder, a smooth periostracum and a small operculum. The shoulder of the shell is usually nodulose and the protoconch is usually multispiral. Markings often include the presence of tents except for black or white color variants, with the absence of spiral lines of minute tents and textile bars.
- Radular tooth (not known for fossil species)
- The radula has an elongated anterior section with serrations and a large exposed terminating cusp, a non-obvious waist, blade is either small or absent and has a short barb, and lacks a basal spur.
- Geographical distribution
- These species are found in the Indo-Pacific region.
- Feeding habits
- These species eat other gastropods including cones.[3]
- Shell characters (living and fossil species)
- Subgenus Jaspidiconus Petuch, 2003
- Shell characters (living and fossil species)
- The shell is turbinate in shape. The protoconch is paucispiral with 1.5 whorls. The anal notch is deep, and the anterior notch is absent. The early whorls are not nodulose but may be ornamented by an undulating carina. Later whorls may be ornamented with nodules. Cords are absent on the whorls. The periostracum is smooth, and the operculum is small.
- Radular tooth (not known for fossil species)
- The anterior sections of the radular tooth is shorter than the posterior section, and the blade is short. A posterior fold is present, and the posterior blade is absent. A basal spur is present, and the barb is short. A shaft fold is present and is blunt at its anterior end.
- Geographical distribution
- These species are found in the West Atlantic region.
- Feeding habits
- These species are vermivorous, meaning that they prey on polychaete worms.[3]
- Shell characters (living and fossil species)

Significance of "alternative representation"
[edit]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.[3] Published accounts of genera within the Conidae (or Conilithidae) that include the genus Jaspidiconus include J.K. Tucker & M.J. Tenorio (2009), and Bouchet et al. (2011).[4][5]
Testing in order to try to understand the molecular phylogeny of the Conidae was initially begun by Christopher Meyer and Alan Kohn,[6] and is continuing, particularly with the advent of nuclear DNA testing in addition to mDNA testing.
However, in 2011, some experts still prefer to use the traditional classification, where all species are placed in Conus within the single family Conidae: for example, according to the current November 2011 version of the World Register of Marine Species, all species within the family Conidae are in the genus Conus. The binomial names of species in the 82 cone snail genera listed in Tucker & Tenorio 2009 are recognized by the World Register of Marine Species as "alternative representations."[7] Debate within the scientific community regarding this issue continues, and additional molecular phylogeny studies are being carried out in an attempt to clarify the issue.[3][5][8][9][10][11][12][13][14][15][16][17][18][19][20][21]
All this has been superseded in 2015 by the new classification of the Conidae [2]
