2005 taxonomy
In the taxonomy by Bouchet & Rocroi (2005), the clade Sorbeoconcha was declared a taxon of unspecified rank, within the clade Caenogastropoda.
It comprises the superfamily Cerithioidea, the superfamily Campaniloidea, the informal group Ptenoglossa and the clade Neogastropoda.
The following extinct families were not allocated to a superfamily:
† Acanthonematidae Wenz, 1938
† Canterburyellidae Bandel, Gründel & Maxwell, 2000
† Prisciphoridae Bandel, Gründel & Maxwell, 2000
The World Register of Marine Species considers Sorbeoconcha an alternate representation of Caenogastropoda and gives the following reasoning:
