Angarioidea

The superfamily Angarioidea was created as a new superfamily by Williams et al. (2008).^[2] The same suggest that something similar may be done in the future for Arene, but Bouchet & Rocroi (2005) note that Areneinae McLean, 2001, introduced in a congress abstract, is not an available family-level name.^[1]

This superfamily consists of the two following families:^[2]

• Angariidae Gray, 1857 - only one genus Angaria Röding, 1798
• Areneidae - Areneidae is however not officially described as a taxon name.^[3] Areneidae is provisionally placed within the superfamily Angarioidea according to Williams et al. (2008).^[2] It contains two genera: Arene Adams, 1845 and Cinysca Killburn, 1970.^[3]

Both are now placed in the superfamily Trochoidea.^[1]
