Nomenclature
Both this genus and its type species have had a very complicated synonymy. The status of the generic name ''Spiralinella'' in contrast to the names ''Partulida'' and ''Spiralina'' was clarified by Corgan (1973), and the nomenclatorical problems around the type species were discussed by van Aartsen & Gianuzzi-Savelli (1991).
Life habits
Little is known about the biology of the members of this genus. As is true of most members of the
Pyramidellidae ''
sensu lato'', they are most likely to be
ectoparasites.
