The 2023 FMCS list of freshwater gastropods from Canada, Mexico and the United States. Mexican species checklist follows Czaja et al., 2020 Revista Mexicana de Biodiveridad. https://doi.org/10.22201/ib.20078706e.2020.91.2909 . Column headings are family, taxon (binomen) and species author(s), and AFS common names (Classification Uncertain denotes uncertain taxonomic status under common names), Family names are followed by the number of genera and species (or monotypic). Species revisions denoted in BLUE LETTERS signify petition changes completed in 2019. Species revisions denoted in RED LETTERS signify petitioned changes completed in 2021. Species revisions denoted in PURPLE LETTERS indicate petitions changes for the 2023. The goal of the FMCS Names Subcommittee is to improve science communication, provide up-to-date authoritative checklists, and promote freshwater mollusk systematics research. Stakeholders are under no obligation to follow the taxonomic opinions expressed in this list.
