''Africonus'' is a subgenus of sea snails, marine gastropod mollusks in the genus Conus, family Conidae, the cone snails and their allies. In the new classification of the family Conidae by Puillandre N., Duda T.F., Meyer C., Olivera B.M. & Bouchet P. (2015), ''Africonus'' has become a subgenus of ''Conus'': ''Conus (Lautoconus)'' Monterosato, 1923 (type species: ''Conus mediterraneus'' Hwass in Bruguière, 1792) represented as ''Conus'' Thiele, 1929 〔 ( Puillandre N., Duda T.F., Meyer C., Olivera B.M. & Bouchet P. (2015). ''One, four or 100 genera? A new classification of the cone snails''. Journal of Molluscan Studies. 81: 1-23 ) 〕 ==Distinguishing characteristics== The Tucker & Tenorio 2009 taxonomy distinguishes ''Africonus'' from ''Conus'' in the following ways:〔Tucker J.K. & Tenorio M.J. (2009), Systematic Classification of Recent and Fossil Conoidean Gastropods, ConchBooks, Hankenheim, Germany, 295 pp.〕 * 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 ''Africonus'' Petuch, 1975 ::Shell characters (living and fossil species) :::The protoconch is paucispiral, the whorl tops may be concave when viewed in cross section, with cords on the whorl tops that may be lost in middle spire whorls or persist thereafter. The shell has a shallow to moderately deep anal notch. The periostracum is smooth and thin, and the operculum is small. ::Radular tooth (not known for fossil species) :::The anterior section of the radula is usually shorter than the posterior section but in some species they are subequal in length, the lumen of the radular tooth is wide, a basal spur is present, the barb is short, and the blade is long and extends along most of the anterior section of the radular tooth. Serrations are usually in multiple rows with one or two rows of large serrations and rows of smaller serrations on either side, although serrations can be in a single row in juveniles or small specimens. ::Geographical distribution :::These species are endemic to the Cape Verde Islands in the West African Region. ::Feeding habits :::These species are vermivorous (meaning that they prey on marine worms).〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Africonus」の詳細全文を読む スポンサード リンク
