Gastrodontoidea

Durgellina calculosa, from Moorea Biocode.


Belongs within: Stylommatophora.

The Gastrodontoidea are a group of mostly small snails, characterised by reductions in the stimulators and lung venation.

See also: Wild slug chases (Taxon of the Week: Gastrodontoidea).

Synapomorphies (from Hausdorf 1998): Stimulator section A5 absent; stimulator section A2 without papilla (reversed in some taxa if synapomorphic); lung without distinct minor venation (reversed in some taxa if synapomorphic).
