Odostomiinae, ''Odostomia'' snails and their allies, is a taxonomic subfamily of minute parasitic sea snails. These are marine heterobranch gastropod mollusks, or micromollusks, in the family Pyramidellidae. ==Taxonomy== The subfamily Odostomiinae has been recognized as monophyletic. It includes the tribe Liostomini, a name given to those genera which have an intorted protoconch. The rest of the genera however do not form a single monophyletic taxon. Subfamily Odostomiinae has been classified as one of eleven recognised subfamilies of the very voluminous gastropod family Pyramidellidae (according to the taxonomy of Ponder & Lindberg 1997): Odostomiinae, Turbonillinae, Chrysallidinae, Cingulininae, Cyclostremellinae, Sayellinae, Syrnolinae, Eulimellinae, Pyramidellinae, Odostomellinae and Tiberiinae. In the taxonomy of Bouchet & Rocroi (2005), this subfamily also comprises the subfamilies Chrysallidinae, Cyclostremellinae and Odostomellinae, that they have downgraded to the rank of tribe. subfamily Odostomiinae Pelseneer, 1928 *tribe Odostomiini Pelseneer, 1928 *tribe Chrysallidini Saurin, 1958 - formerly subfamily Chrysallidinae *tribe Cyclostremellini D.R. Moore, 1966 - formerly subfamily Cyclostremellinae *tribe Odostomellini Saurin, 1959 - formerly subfamily Odostomellinae According to Schander, Van Aartsen and Corgan (1999) there are 33 genera in Odostominae with four possible additional genera of uncertain status. 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「Odostomiinae」の詳細全文を読む スポンサード リンク
