In the new classification of the family Conidae by Puillandre N., Duda T.F., Meyer C., Olivera B.M. & Bouchet P. (2015), Dauciconus has become a subgenus of Conus: Conus (Dauciconus) Tucker & Tenorio, 2013 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 conical to elongate conical in shape. The
protoconch is multispiral with 2.5 whorls, and the whorl tops are often concave and nodules usually do not persist on later whorls. The anal notch is deep to moderately deep. The
periostracum is tufted, and the operculum is small to medium sized.
Radular tooth (not known for fossil species)
The anterior section of the
radula is roughly equal to the posterior section. The blade is fairly long and covers at least half the length of the anterior section of the
radular tooth. A basal spur is present, and the barb is short. The radular tooth has serrations and the terminating cusp is internal.
Geographical distribution
These species are found in the West Atlantic and Eastern Pacific regions.
Feeding habits
These species are presumed to be
vermivorous (meaning that they prey on marine worms) based upon the aspect of the radular tooth.[3]
Species list
The following species names are recognized as "alternate representations" (see full explanation below) in contrast to the traditional system, which uses the genus Conus for all species in the family:[1]
Dauciconus abrolhosensis Petuch, 1987: synonym of Conus (Dauciconus) abrolhosensis Petuch, 1987, represented as Conus abrolhosensis Petuch, 1987
