Opinion 1957, Sphaerius Waltl, 1838 (Insecta, Coleoptera): conserved; and Sphaeriidae Erichson, 1845 (Coleoptera): spelling emended to Sphaeriusidae, so removing the homonymy with Sphaeriidae Deshayes, 1854 (1820) (Mollusca, Bivalvia). their entire life cycle in freshwater. Recognizes the need for including Sphaeriidae . clams and pea clams (Family Sphaeriidae), and non-native Asian clams (Cor-bicula fluminea) are much smaller than native mussels (less than one inch). In approximately two Heard (1965) compared the life cycles of a number of species of the genus Pisidium found in North America.
