Utah Roundmouth Snail - Taxonomy

Taxonomy

This species was first described as Valvata sincera var. utahensis by Richard Ellsworth Call (1856-1917, U.S.A.) in 1884 from specimens collected at Utah Lake, Utah (the type locality).

R. E. Call elevated Valvata utahensis to species level in 1886 and this was confirmed also in revision of the genus by Bryant Walker (1856-1936, U.S.A.) in 1902.

There was established a subspecies Valvata utahensis horatii Baily & Baily, 1951 from pleistocene, but Taylor (1966) stated, that Valvata utahensis horatii should be a synonym for Valvata utahensis.
