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 [2]
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.
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.
