Taxonomy
The
Caenogastropoda can be divided into two major groups, based on the anatomy of the radula:
- Taenioglossa (from taenio meaning band), equivalent to the older Mesogastropoda, with typically seven teeth in each radular row.
- Stenoglossa (from steno meaning narrow), the Neogastropoda, with only 1–3 teeth per row.
1997 taxonomy
Ponder & Lindberg, 1997 and others since (e.g. Vega et al., 2006;[8] Harzhauser, 2004;[9] and Pina, 2002.[10]) show Caenogastropoda as a superorder, following the sense of Cox, 1960. More recently Bouchet & Rocroi, 2005 revised Caenogastropoda as a clade.
2005 taxonomy
The following classification was laid out in the taxonomy of Bouchet & Rocroi (2005):[7]
- Caenogastropoda of uncertain systematic position
- an informal group Architaenioglossa
- clade Sorbeoconcha
- clade Hypsogastropoda
2006 taxonomy
Colgan et al. (2006)[11] provided further insight into the phylogeny of Caenogastropoda.[2]
Latest views by the World Register of Marine Species
Sorbeoconcha should include [Cerithioidea + Campaniloidea + all Hypsogastropoda (i.e. the remaining Caenogastropoda)], see definition in Ponder & Lindberg, 1997: 225, not only [Cerithioidea + Campaniloidea] as suggested by the indent pattern in Bouchet & Rocroi. Neotaenioglossa Haller, 1892 suggested in Ruud Bank’s draft for Fauna Europaea is not retained because it would need severe emendation to remove Pyramidellids, Cerithioids, etc. included in its original definition, and therefore would be too far from Haller's concept if it were to fit the concept of Sorbeoconcha. Although cladistically sound, the taxon Sorbeoconcha is skipped in the classification scheme because (1) ten years after its publication, the name still sounds unfamiliar to most and (2) it is not very helpful in the classification because it includes the bulk of Caenogastropoda (only keeping out small stem groups Abyssochrysidae, Provannidae, and the architaenioglossate taxa). This is not final, opinions are welcome.[12]
