Lamniconus
Lamniconus is a subgenus  of sea snails, marine gastropod mollusks in the 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), Lamniconus has become a subgenus of Conus as Conus (Lamniconus) da Motta, 1991 (type species: Conus cleerii  Reeve, 1844) represented as Conus Linnaeus, 1758

Distinguishing characteristics
The Tucker & Tenorio 2009 taxonomy distinguishes Lamniconus 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 Lamniconus da Motta, 1991
Shell characters (living and fossil species)
The shell is turbinate to elongate conical in shape.  The protoconch is paucispiral.  The spire is scalariform and concave in cross section.  The shell is ornamented with cords and nodules which die out early in the postnuclear whorls.  The anal notch is deep.  The periostracum is tufted, and the operculum is small.
Radular tooth (not known for fossil species)
The anterior section of the radular tooth is roughly equal in length with the posterior section, the 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, and an internal terminating cusp.
Geographical distribution
The species in this genus occur in the occur in the West Atlantic region.
Feeding habits
These cone snails are presumed to be vermivorous, meaning that the cones prey on polychaete worms, based upon the radular tooth morphology.
