 According to Bouchet & Rocroi, 2005, the superfamily Cocculinoidea contains the families Bathysciadiidae and Cocculinidae.The Cocculinoidea (Cocculinacea Dall, 1882) are combined with the Lepetelliodea (Lepetellacea Dall, 1882) in Cocculinoformia Haszprunar, 1987, referred to as a clade in Bouchet & Rocroi, 2005 although it used to be designated a superorder by Ponder & Lindberg, 1997.Bouchet & Rocroi (2005) leave the Cocculiniformia to consist only of the Cocculinoidea, having moved the Lepetelloidea to the Vetigastropoda.
