Endemoconus

''Endemoconus'' is subgenus of sea snails, marine gastropod mollusks in the genus ''Conasprella'', family Conidae, the cone snails and their allies.〔Bouchet, P. (2015). Endemoconus Iredale, 1931. Accessed through: World Register of Marine Species at http://www.marinespecies.org/aphia.php?p=taxdetails&id=430148 on 2015-03-17〕
In the new classification of the family Conidae by Puillandre N., Duda T.F., Meyer C., Olivera B.M. & Bouchet P. (2015), ''Endemoconus'' has become a subgenus of ''Conasprella'': ''Conasprella (Endemoconus)'' Tucker & Tenorio, 2009 represented as ''Conasprella'' Thiele, 1929. Three species have become synonyms of a ''Conus'' species.〔( Puillandre N., Duda T.F., Meyer C., Olivera B.M. & Bouchet P. (2015). ''One, four or 100 genera? A new classification of the cone snails''. Journal of Molluscan Studies. 81: 1-23 )〕
==Distinguishing characteristics==
The Tucker & Tenorio 2009 taxonomy distinguishes ''Endemoconus'' from ''Conus'' in the following ways:〔Tucker J.K. & Tenorio M.J. (2009), Systematic Classification of Recent and Fossil Conoidean Gastropods, ConchBooks, Hankenheim, Germany, 295 pp.〕
* 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.〔
* Subgenus ''Endemoconus'' Iredale, 1931
::Shell characters (living and fossil species)
:::The shell is turbinate with a scalariform spire. The protoconch is either paucispiral or multispiral. Whorl tops are concave and do not have cords. Nodules may be absent or may be present and persist on all whorls. A dentiform plait is present. The anal notch is shallow, and the anterior notch is absent. The periostracum is tufted and the operculum is small to moderate in size.
::Radular tooth (not known for fossil species)
:::The anterior section of the radula is much longer than the posterior section. The blade is short, a basal spur is absent, and the barb is short. The radular tooth has no serrations. An accessory process is present and is a short, simple triangular terminating cusp.
::Geographical distribution
:::These species are found from Australia to New Zealand and in Madagascar.
::Feeding habits
:::Unknown, however these species are believed to be piscivorous based upon Bayesian cladistics analysis.〔
