Elachorbis is a genus of minute sea snails or micromolluscs, marine gastropod molluscs in the family Tornidae.[3][4]
Taxonomy
The exact placement of this genus has long been contested.
Tom Iredale established Elachorbis in 1914 within the family Liotiidae.[2] Cotton (1945)[5] also classified Elachorbis within the family Liotiidae. Powell (1979)[1] and ITIS (2011)[6] classified Elachorbis within the family Cyclostrematidae (which is a synonym of Liotiidae).[7]
Various authors have classified this genus in the Skeneidae, which is now the Skeneinae, a subfamily within the Turbinidae.
The genus Elachorbis is sometimes referred to the subfamily Vitrinellinae within the family Tornidae.[3][4] However, Elachorbis is also sometimes considered to be a synonym of Circulus;[4] Circulus is the type genus of the subfamily Circulinae within the Tornidae.[7]
Species
Species within the genus Elachorbis include:
- Elachorbis diaphana Finlay, 1924[8]
- Elachorbis subtatei (Suter, 1907)[9]
- Elachorbis tatei (Angas, 1878)[3] - type species of the genus Elachorbis[2] - synonyms: Cyclostrema tatei Angas, 1878; Circulus tatei (Angas, 1878)
