Elachorbis Explained

Elachorbis is a genus of minute sea snails or micromolluscs, marine gastropod molluscs in the family Tornidae.

Taxonomy

The exact placement of this genus has long been contested.

Tom Iredale established Elachorbis in 1914 within the family Liotiidae. Cotton (1945)^[1] also classified Elachorbis within the family Liotiidae. Powell (1979) and ITIS (2011)^[2] classified Elachorbis within the family Cyclostrematidae (which is a synonym of Liotiidae).

Various authors have classified this genus in the Skeneidae, which is now the Skeneinae, a subfamily within the Turbinidae.

See main article: Circulus (gastropod). The genus Elachorbis is sometimes referred to the subfamily Vitrinellinae within the family Tornidae.^[3] However, Elachorbis is also sometimes considered to be a synonym of Circulus;^[3] Circulus is the type genus of the subfamily Circulinae within the Tornidae.
