Syrnolidae
Syrnolininae is a subfamily of minute parasite, parasitic sea snails, marine (ocean), marine heterobranch gastropod molluscs in the family (biology), family Pyramidellidae, the pyrams and their allies. Taxonomy According to the taxonomy of Winston Ponder, Ponder & David R. Lindberg, Lindberg (1997), this was one of eleven recognised subfamilies in the family Pyramidellidae. In the Taxonomy of the Gastropoda (Bouchet & Rocroi, 2005), taxonomy of Bouchet & Rocroi (2005), this subfamily also comprises the subfamily Tiberiinae, downgraded to the rank of tribe (biology), tribe Tiberiini.

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 micromolluscs 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] |
