''Kohniconus'' is a subgenus of sea snails, marine gastropod mollusks in the genus ''Conasprella'', family Conilithidae, the cone snails and their allies.〔Bouchet, P. (2015). Kohniconus Tucker & Tenorio, 2009. Accessed through: World Register of Marine Species at http://www.marinespecies.org/aphia.php?p=taxdetails&id=571643 on 2015-03-17〕 This subgenus was named in honor of Alan J. Kohn, the cone shell authority.〔Tucker J.K. & Tenorio M.J. (2009), Systematic Classification of Recent and Fossil Conoidean Gastropods, ConchBooks, Hankenheim, Germany, 295 pp.〕 In the new classification of the family Conidae by Puillandre N., Duda T.F., Meyer C., Olivera B.M. & Bouchet P. (2015), ''Kohniconus'' has become a subgenus of ''Conasprella'': ''Conasprella (Kohniconus)'' Tucker & Tenorio, 2009 represented as ''Conasprella'' 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 ''Kohniconus'' 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 ''Kohniconus'' Tucker & Tenorio, 2009 ::Shell characters (living and fossil species) :::The shell is turbinate in shape. The protoconch is multispiral. The shell is ornamented with cords and nodules which may persist or become obsolete. The anal notch is deep. The periostracum is smooth, and the operculum is large. ::Radular tooth (not known for fossil species) :::The anterior section of the radular tooth is much shorter than the posterior section, and a short blade is present. A basal spur is present, and the barb is short. The shaft fold is blunt at the anterior end. ::Geographical distribution :::The species in this genus occur in the West Atlantic and Eastern Pacific regions. ::Feeding habits :::The species in this genus are vermivorous (meaning that these snails 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「Kohniconus」の詳細全文を読む スポンサード リンク
