Chrysallida is a speciose genus of minute sea snails, pyramidellid gastropod mollusks or micromollusks in the family Pyramidellidae within the tribe Chrysallidini. [2] [3] [4]
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 ChrysallidaCarpenter, 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 include many Eastern Atlantic species, distributed into several subgenera. Micali, Nofroni & Perna (2012) restored usage of Parthenina Bucquoy, Dautzenberg & Dollfus, 1883 for several species formerly placed in Chrysallida. This move was continued by Høisæter (2014), Peñas, Rolán & Swinnen (2014) and Giannuzzi-Savelli et al. (2014) who are here followed, but there are still many species remaining unduly under Chrysallida. For these, we have refrained from making new combinations not backed by (or implicit from) a published source. Nevertheless, all the species that were already "accepted" under a subgenus, now raised to full genus, have been marked as "accepted" under that full genus. [5]
Species within the genus Chrysallida are commonly distributed in all oceans from the tropics to the polar regions, the Arctic and the Antarctic. It is mainly known from coastal areas, and is uncommon in deep elevations such as trenches in the sea.
The members of Chrysallida are ectoparasites on serpulid polychaetes.
There are multiple species within the genus Chrysallida, these include the following in alphabetical order: [5]
The following species were brought into synonymy [5]
Little is known about the ecology of the members of this genus. As is true of most members of the Pyramidellidae sensu lato , they are most likely ectoparasites.
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.
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.
Turbonillinae is a subfamily of mostly minute parasitic sea snails, marine gastropod molluscs in the family Pyramidellidae, the pyrams and their allies.
Chrysallidinae is a taxonomic group of very small sea snails, marine gastropod mollusk in the family Pyramidellidae, the pyrams and their allies.
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.
