In addition to the truncatellids, members of at least eight groups of snails have independently invaded land: Neritoidea (helicinids and hydrocenids), Cyclophoroidea (all terrestrial), Littorinoidea (pomatiasids and annulariids), Pomatiopsidae (Blanfordia), Hydrobiidae (Falniowskia Bernasconi, 1990 and Terrestribythinella Sitnikova, Starobogatov and Anistratenko, 1992), Assimineidae (omphalotropidines), Basommatophora (carychiids) and Stylommatophora (typical pulmonate land snails).
