With their phylogenetic analysis of rissooidean and cingulopsoidean families, Criscione F. & Ponder W.F. (2013) have created the superfamily Truncatelloidea containing many families previously included in the superfamily Rissooidea. They have shown that Rissooidea was not monophyletic, encompassing two major clades, i.e. Risooidea s.s. and Truncatelloidea. The freshwater, brackish water, and semi-terrestrial families and genera were brought under Truncatelloidea.
