Emmericiidae is a family of freshwater gastropods in the superfamily Truncatelloidea, living in lakes and rivers.[1][2] There are a few species alive in the type genus, Emmericia, but the vast majority of species are extinct.[1] The type genus Emmericia was first described by the notable Croatian malacologist Spiridion Brusina in November 1870, although its type species, E. patula, was originally classified as Paludina patula by Brumati in 1838.[3] Measuring the number of extant Emmericia species is highly problematic, causing "taxonomic chaos with from one to sixty-seven species recognized in Emmericia."[4] The family Fontigentidae has previously been considered to be a subfamily, Fontigentinae, of Emmericiidae; however, more recent phylogenetic analysis recovers them as the sister group of the Bythinellidae, with Emmericiidae being more distantly related.[5]
