Overview |
Included here are a small group of pulmonates that might be closely related to the Stylommatophora, or even possibly ancestral to them. Their taxonomic position has varied over the past decades. The Ellobioidea are included under the Order Basommatophora in Macpherson & Gabriel 1962), and the superfamily Ellobioidea in Salvini-Plawen's 1980) order Archaeopulmonata by Vaught 1989). But Jeffery 2001 includes the Ellobioidea in the clade Acteophila, in turn a subclade of the Eupulmonata (which also includes the Trimusculiformes and the Stylommatophora.
These animals inhabit salt marshes and mangroves near the sea. Most members of the family are tropical. The shell is rather solid, the aperture contracted by columnella teeth, although the inner walls of the shell are usually absorbed, leaving a single cavity. Macpherson & Gabriel (1962).
The following classification is from Jeffery 2001).
