†SUPERFAMILY ELMINOIDEA SUPERFAM. NOV. (OLIGOCENE–RECENT)

Diagnosis: Six- or four-plated shells with solid parietes, without chitinous laminae or stringers and interlaminate figures; radii solid; basis membranous.

Comment: This superfamily contains only a single family but is created for formal reasons, because the Elminiidae diverge phylogenetically between the Chthamaloidea and the clade consisting of the Coronuloidea + Balanoidea .
