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.

Main article: Circulus (gastropod)

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]
