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.^{[citation needed]}

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]
