Taxonomy of the Gastropoda (Ponder & Lindberg, 1997)

The taxonomy of the Gastropoda, as revised by Winston Ponder and David R. Lindberg in 1997, is an older taxonomy of the class Gastropoda, the class of molluscs consisting of all snails and slugs.[1] The full name of the work in which this taxonomy was published is Towards a phylogeny of gastropod molluscs: an analysis using morphological characters.

This taxonomy assigns the various Gastropods into ranked categories, such as sub-orders and families, but does not address the classification of genera or individual species. This classification scheme is based on the molluscs' internal and external shapes and forms, but did not take into account any analysis of their DNA or RNA.

The classification below was the most recent until Bouchet and Rocroi published their revised taxonomy in 2005, which differs primarily in that the higher taxa are expressed as unranked clades where known, and termed "informal groups" or groups" where monophyly (a single lineage) has not yet been determined, and where polyphyly (more than one lineage) is suspected.

Ponder & Lindberg (1997) used only four families to analyze the Euthyneura. Further work by Dayrat & Tillier (2002)[2] provided a great deal of detail about the relationships between within the Euthyneura.

Ponder & Lindberg (1997) did not use Linnean taxonomical ranks in their work, but the results of their paper were widely adapted and used with Linnean taxonomical ranks by other authors. An example of such taxonomy follows:


Class Gastropoda Cuvier, 1797
Incertæ sedis

Subclass Eogastropoda Ponder & David R. Lindberg, 1996 (earlier: Prosobranchia)

Live limpets in the intertidal zone in Cornwall, England.

Subclass Orthogastropoda Ponder & David R. Lindberg, 1996 (earlier Prosobranchia, Opisthobranchia)
Incertæ sedis

Superorder Cocculiniformia Haszprunar, 1987

Superorder "Hot Vent Taxa" Ponder & David R. Lindberg, 1997

Superorder Vetigastropoda Salvini-Plawen, 1989 (limpets)

The shell of an archaeogastropod from the Pliocene of Cyprus. A serpulid worm is attached.

Superorder Neritaemorphi Koken, 1896

Superorder Caenogastropoda Cox, 1960

Superorder Heterobranchia J.E. Gray, 1840

Cochlodina laminata from the family Clausiliidae or door snails, a small land pulmonate which has a sinistral or left-handed shell, on the trunk of a tree, in woodland, England

Other extant classes of the Mollusca are Bivalvia, Scaphopoda, Aplacophora, Polyplacophora, Monoplacophora and Cephalopoda.
