Leptoconus

Leptoconus is a subgenus of sea snails, marine gastropod mollusks in the genus Conus, family Conidae, the cone snails and their allies.

In the latest classification of the family Conidae by Puillandre N., Duda T.F., Meyer C., Olivera B.M. & Bouchet P. (2015), Leptoconus has become a subgenus of Conus as Conus (Leptoconus) Swainson, 1840 (type species: Conus amadis Gmelin, 1791 ) represented as Conus Linnaeus, 1758

Distinguishing characteristics
The Tucker & Tenorio 2009 taxonomy distinguishes Leptoconus from Conus in the following ways:


 * 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 Leptoconus Swainson, 1840
 * Shell characters (living and fossil species)
 * The shell is turbinate to elongated conical in shape, and the spire is either concave or straight and turriculated in profile. The protoconch has 1.5 whorls.  The shell is ornamented with nodules which may persist or die out early.  The anal notch is deep.  The color pattern includes spiral rows of minute tents, however textile bars are absent.  The periostracum is smooth, and the operculum is small.
 * Radular tooth (not known for fossil species)
 * The anterior section of the radular tooth is significantly longer than the length of posterior section. A basal spur is usually absent, and the barb and blade are short.  The waist is not obvious.  The radular tooth has serrations, and a terminating cusp.
 * Geographical distribution
 * These species are found in the Indo-Pacific region.
 * Feeding habits
 * These species are molluscivorus, meaning that these cone snails prey on other mollusks.
