Description:
The superfamily Orthalicoidea comprises approximately 2,000 species of terrestrial gastropods, mostly concentrated in the Neotropics but also present in southern Africa and Oceania. We provide a multi-marker molecular phylogeny of this superfamily, reassessing its
\nfamily- and genus-level classification. We exclude two families from the group, Odontostomidae and Vidaliellidae, transferring them to Rhytidoidea based on their phylogenetic relationships as recovered herein. Two new families are recognized herein as members of
\nOrthalicoidea, Tomogeridae and Cyclodontinidae fam. nov. The family Megaspiridae and
\nthe subfamily Prestonellinae are paraphyletic but are retained herein for taxonomic stability.
\nThe subfamily Placostylinae is synonymized with Bothriembryontinae. The new genera
\nAlterorhinus gen. nov. and Sanniostracus gen. nov. containing some Brazilian species are
\ndescribed here to better reflect the phylogeny. The fossil record and paleobiogeographic
\nhistory of the group is explored under the new phylogenetic framework.
