Lautoconus
Lautoconus 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), Lautoconus has become a subgenus of Conus as Conus (Lautoconus) Monterosato, 1923(type species: Conus mediterraneus Hwass in Bruguière, 1792) represented as Conus Linnaeus, 1758

Distinguishing characteristics
The Tucker & Tenorio 2009 taxonomy distinguishes Lautoconus 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 Lautoconus Monterosato, 1923
Shell characters (living and fossil species)
The shell is turgid in shape with convex sides.  The protoconch is paucispiral.  The whorl tops are ornamented with cords that reach the middle spire whorls and often persist.  The anal notch is shallow to moderate in depth.  The periostracum is smooth and thin, and the operculum is of moderate size.
Radular tooth (not known for fossil species)
The anterior section of the radular tooth is equal to shorter than the posterior section, and blade is long and covers most of the anterior section.  A basal spur is present, and the barb is short.  The radular tooth has serrations in one or two rows.
Geographical distribution
The species in this genus occur in the occur in the West African and Mediterranean regions..
Feeding habits
These cone snails are vermivorous, meaning that the cones prey on polychaete worms.
