Semisulcospiridae, common name semisulcospirids, is a family of freshwater snails, aquatic gilled gastropod mollusks with an operculum, in the superfamily Cerithioidea.
Semisulcospiridae diversified from the Pleuroceridae about 90 millions years ago, in the Cretaceous.
The family Semisulcospiridae occurs in western North America, the Far East of Russia, Korea, Japan, China and Vietnam.
The family Semisulcospiridae was introduced as just a name (nomen nudum) by Morrison (1952), without a diagnosis of the taxon. It is a valid taxon however, because its name has been used as valid.
According to the taxonomy of Bouchet & Rocroi (2005), Semisulcospiridae was a subfamily within the family Pleuroceridae.
The subfamily Semisulcospirinae within the Pleuroceridae was elevated to family level as Semisulcospiridae by Strong & Köhler (2009).
There is very high level of mitochondrial heterogeneity in apparent species of Semisulcospiridae (highest among gastropods, also with Pleuroceridae), that has not been sufficiently explained yet as of 2015.
Genera within the family Semisulcospiridae include:
