Shell description

Shells in this superfamily attain a wide variety of lengths depending on the species (20-400 mm^[2] from the smallest aporrhaids to the largest strombids).

Taxonomy

This superfamily was previously known as Strombacea. Prior to the recent ruling by the ICZN, many invertebrate superfamily names ended in the suffix -acea, or -aceae, not -oidea as now required according the ICZN article 29.2. The suffix -oidea used to be used for some subclasses and superorders, where it is stll found. In much of the older literature including Keen 1958, Moore et al. 1952, and the Treatise on Invertebrate Paleontology, gastropod superfamilies are written with the suffix -acea.^[3][4][5]

2005 taxonomy

According to the classification proposed by Bouchet & Rocroi (2005)^[6], the families and subfamilies in the superfamily Stromboidea are as follows. Fossil families are marked with a dagger †.

• Aporrhaidae Gray, 1850 - the pelican's foot shells, synonyms: Aporrhaididae, Aporrhaiidae,
  • Subfamily Aporrhainae Gray, 1850
  • Subfamily Arrhoginae Popenoe, 1983
  • † Subfamily Harpagodinae Pchelintsev, 1963
  • † Subfamily Perissopterinae Korotkov, 1992
  • † Subfamily Spinigerinae Korotkov, 1992 (inv.)
• † Colombellinidae P. Fischer, 1884
• † Pugnellidae Kiel & Bandel, 1999
• Seraphsidae Gray, 1853 - synonym: Terebellidae
• Strombidae Rafinesque, 1815 - the "true conchs"
• Struthiolariidae Gabb, 1868
• † Thersiteidae Savornin, 1915
• Tylostomatidae Stoliczka, 1868

2008 taxonomy

Some authors consider two following families as separate families:

• Rimellidae
• Rostellariidae - synonym: Tibiidae

Cladogram

A cladogram, based on an extensive morpho-anatomical analysis of representatives of Aporrhaidae, Strombidae, Xenophoridae and Struthiolariidae was proposed by Simone (2005).^[7] A simplified version of this analysis is represented bellow (Cuphosolenus and Aporrhais belongs to Aporrhaidae):

Struthiolariidae	Struthiolaria papulosa Tylostira scutulata
	Cuphosolenus serresianus Aporrhais occidentalis Aporrhais pespelicani Xenophoridae Xenophora conchyliophora Onustus caribaeus Onustus indicus Strombidae ►
