Stylommatophora is an

gastropod molluscs. This taxon includes most land snails and slugs

The two strong synapomorphies of Stylommatophora are a long pedal gland placed beneath a membrane and two pairs of retractile tentacles (Dayrat & Tillier).[citation needed]

Several families in this group contain species of snails and slugs that create love darts.

Stylommatophora are known from the Cretaceous period up to the present day.[4]

2005 taxonomy

According to the taxonomy of the Gastropoda by Bouchet & Rocroi (2005) based on evolutionary ancestry is the clade Stylommatophora in clade Eupulmonata within informal group Pulmonata. It uses unranked clades for taxa above the rank of superfamily (replacing the ranks suborder, order, superorder and subclass) and the traditional Linnaean approach for all taxa below the rank of superfamily.
