Abstract:

The authors review the freshwater and terrestrial mollusks of Idaho, using historic data and data from sites collected between 1988 and 2000. This annotated checklist is the first complete such checklist since Henderson (1924, 1936). As recognized here, the Idaho malacofauna Includes at least 266 taxa. There are at least 149 terrestrial taxa (128 land snails and 20 slugs), of which some 124 land snails and 8 slugs are thought to be native. Freshwater mollusks include some 117 taxa: about 87 gastropods (75 likely native), 7 larger bivalves or freshwater mussels, and about 23 Sphaerlidae (fingernail clams). A substantial portion of the mollusk fauna (about 34%) is endemic to the state, and 17% (minimum, but perhaps as high as 40% or more) are undescribed, suggesting that this element of the Idaho biota deserves considerable further attention from biologists. Many taxa have small ranges and are known from relatively few sites.
