Abstract
This technical note provides an illustrated key to the 13 genera and a checklist for
the 178 currently recognized species of freshwater, inland saline, and estuarine
truncatelloidean gastropods (primarily belonging to the families Amnicolidae,
Cochliopidae, Hydrobiidae, Lithoglyphidae, and Tateidae) in the western United
States. It also outlines methods of specimen preparation and dissection to facilitate use
of the generic key. The checklist includes bibliographic information for each species
(and their synonyms), type localities, type material, and geographic distributions.
The appendix includes a comprehensive synopsis of the available DNA barcoding
sequences (the COI gene, cytochrome c oxidase subunit I) for members of this fauna
in the anticipation that these data will be increasingly used for both taxonomic and
conservation genetic applications. This technical note serves as an entry portal for
resource managers, taxonomists, and other individuals interested in this species-rich
and highly imperiled fauna.
