Pyramidellidae
Pyramidellidae, common name the pyram family, or pyramid shells, is a voluminous taxonomic family of mostly small and minute ectoparasitic sea snails, marine heterobranch gastropod molluscs. The great majority of species of pyrams are micromolluscs. The pyram family is distributed worldwide with more than 6,000 named species in more than 350 nominal genera and subgenera. This family of micromollusks has been little studied and the phylogenetic relationships within the family are not well worked out. There is an absence of a general consensus regarding which species belong to a specific genus or subgenus, contributing to much confusion. Schander (1999) names more than 300 supraspecific names. As there has been no serious generic revision of the genera worldwide, generic polyphyly can be expected to be rampant throughout the family. However, the family itself is deemed monophyletic. However a study in 2011 seems to indicate that this family is deeply nested within the Pulmonata ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Odostomiinae
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 ...

Tribe (biology)
In biology, a tribe is a taxonomic rank above genus, but below family and subfamily. It is sometimes subdivided into subtribes. By convention, all taxonomic ranks from genus upwards are capitalized, including both tribe and subtribe. In zoology, the standard ending for the name of a zoological tribe is "-ini". Examples include the tribes Caprini (goat-antelopes), Hominini (hominins), Bombini (bumblebees), and Thunnini (tunas). The tribe Hominini is divided into subtribes by some scientists; subtribe Hominina then comprises "humans". The standard ending for the name of a zoological subtribe is "-ina". In botany, the standard ending for the name of a botanical tribe is "-eae". Examples include the tribes Acalypheae and Hyacintheae. The tribe Hyacintheae is divided into subtribes, including the subtribe Massoniinae. The standard ending for the name of a botanical subtribe is "-inae". In bacteriology, the form of tribe names is as in botany, e.g., Pseudomonadeae, based on the ge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tiberiinae
''Tiberia'' is a genus of minute parasitic sea snails, marine gastropod molluscs in the family Pyramidellidae, the pyrams and their allies. ''Tiberia'' is the only genus in the tribe Tiberiini. Taxonomy According to Schander, Van Aartsen & Corgan (1999) the subfamily Tiberiinae contains a single genus, ''Tiberia''. Tiberiinae was one of eleven recognised subfamilies in the family Pyramidellidae according to the taxonomy of Ponder & Lindberg (1997). However, in the taxonomy of Bouchet & Rocroi (2005), this subfamily was downgraded to the rank of tribe Tiberiini in the subfamily Syrnolinae. ''Tiberia'' is the type genus of the tribe Tiberiini. Description The very small shells of the species in this genus have many whorls. They are umbilicate shells that lack both shell sculpture and the apertural tooth or teeth that are characteristic in most other members of the family Pyramidellidae. They may, however, have slight biplicate folds on the columella. Species Speci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Schander
Carl Fredrik Christoffer Schander (21 May 1960 – 21 February 2012) was a professor in marine biology at the University of Bergen, Norway. He was also a thematic leader at the Centre of Excellence in Geobiology. His doctoral thesis (1997, University of Gothenburg, Sweden) explored the evolutionary relationships of the parasitic marine gastropod family Pyramidellidae. He worked on marine invertebrates, mainly molluscs, and published more than 90 scientific papers in peer-reviewed journals, 76 are indexed in the Web of Knowledge, and fourteen of them have been cited ten or more times. According to his web page, he considered the goal of his research to be understanding the roles that evolutionary forces and phylogeny have played in creating organismal diversity. To help develop this understanding, he used phylogenetic analyses that integrated morphological, ultrastructural and molecular data. His research focused on molluscs and more specifically on the ectoparasitic pyramidelli ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
