Chrysallidini
Chrysallidinae is a taxonomic group of very small sea snails, marine gastropod mollusk in the family Pyramidellidae, the pyrams and their allies. Taxonomy Chrysallidinae has been one of eleven recognized subfamilies of the gastropod family Pyramidellidae (according to the taxonomy of Ponder & Lindberg 1997). (The other 10 subfamilies are Odostomiinae, Turbonillinae, Cingulininae, Cyclostremellinae, Sayellinae, Syrnolinae, Eulimellinae, Pyramidellinae, Odostomellinae and Tiberiinae.) According to Schander, Van Aartsen & Corgan (1999) there are 47 genera in this subfamily, four additional genera may also be a part of this taxon. In the taxonomy of Bouchet & Rocroi (2005), this subfamily has been downgraded to the rank of tribe Chrysallidini in the subfamily Odostomiinae. Genera Genera in the subfamily Chrysallidinae include: * ''Chrysallida'' Carpenter, 1856 - type genus * ''Babella'' Dall, & Bartsch, 1906 * ''Bartrumella'' Laws, 1940 * '' Besla'' Dall & Bartsch, 1904 * '' ...

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 ...

Babella
''Babella'' is a genus of very small sea snails, pyramidellid gastropod mollusks or micromollusks in the family Pyramidellidae within the tribe Chrysallidini (sensu taxonomy by Bouchet & Roctroi, 2005).Bouchet, P.; Gofas, S.; Rosenberg, G. (2018). Babella Dall & Bartsch, 1906. In: MolluscaBase (2018). Accessed through: World Register of Marine Species at http://www.marinespecies.org/aphia.php?p=taxdetails&id=588302 on 2018-01-08 Description The shell shows strong axial ribs between the sutures and three spiral keels, two of which are at the periphery, which falls in the deep sulcus between them, and one a little anterior to the middle of the base. Distribution The genus seems to be limited to tropical and temperate regions of the Pacific Ocean. Life habits Little is known about the biology of the members of this genus. As is true of most members of the Pyramidellidae ''sensu lato'', they are ectoparasites. Species There are twelve known species within the genus ''Babella'', ...

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] |

Besla
''Besla'' is a small genus of miniature sea snails, pyramidellid gastropod mollusks in the family Pyramidellidae within the tribe Chrysallidini (sensu taxonomy by Bouchet & Roctroi, 2005).Gofas, S.; Bouchet, P. (2012). Besla Dall & Bartsch, 1904. Accessed through: World Register of Marine Species at http://www.marinespecies.org/aphia.php?p=taxdetails&id=571798 on 2012-08-27 Taxonomy The synonymy of ''Parthenina'' (Bucquoy, Dautzenberg & Dolfus, 1883) with ''Besla'' (Doll & Bartsch, 1904) proposed by Micali ''et al.,'' (2012) is debatable. The type species of ''Besla'' has a protoconch axis at 90° with that of teleoconch ''(Type A'' ''protoconch),'' whereas that of ''Parthenina'' is tilted at nearly 180° ''(Type C);'' therefore, these divergent characteristics suggest that ''Besla'' and ''Parthenina'' are unrelated and that their teleoconch sculpture may be convergent .Micali P., Nofroni I. & Perna E.

Bartrumella
''Bartrumella'' is a small genus of miniature sea snails, pyramidellid gastropod mollusks or micromollusks in the family Pyramidellidae within the tribe Chrysallidini (sensu taxonomy by Bouchet & Roctroi, 2005). Etymology The genus is named after Professor and Mrs. John Arthur Bartrum (1885–1949), of Takapuna, Auckland. Shell description The shell of ''Bartrumella'' is high spired with a well-developed columellar lamella, which gives the appearance of a tooth in the aperture. There are axial ribs and fine spiral sculpture in the form of raised intercostal threads which are only visible through a hand lens or microscope. The spiral sculpture is present on all whorls and on the base. This sculpture is stronger towards the apical side of the whorls, and in that area there are nodules where the spiral and axial sculpture cross. The axial sculpture evanesces gradually on the base. The protoconch is intorted (planorboid). The original description of the genus and type species ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chrysallida
''Chrysallida'' is a speciose genus of minute sea snails, pyramidellid gastropod mollusks or micromollusks in the family Pyramidellidae within the tribe Chrysallidini.Spencer, H.; Marshall. B. (2009). All Mollusca except Opisthobranchia. In: Gordon, D. (Ed.) (2009). New Zealand Inventory of Biodiversity. Volume One: Kingdom Animalia. 584 pp Taxonomy The genus ''Folinella'' had two preoccupied names - ''Amoura'' De Folin, 1873 ''not'' J.E. Gray 1847, and ''Funicularia'' Monterosato, 1884 ''not'' Forbes, 1845. The genus ''Chrysallida'' Carpenter, 1856 has been used as a catchall, particularly in the European literature following a lead by Winckworth (1932), for most pyramidellids having both axial and spiral sculpture but having otherwise little in common with the Californian type species ''C. communis'' (C. B. Adams, 1852). A statement that this is incorrect was voiced by van Aartsen, Gittenberger & Goud (2000: 21) who nevertheless still used ''Chrysallida'' as the genus to ...
