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 [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 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.[3]
