==Species== There are four<ref name ="Davis 1979"/> species within the genus ''Pomatiopsis'':
* ''Pomatiopsis binneyi'' <small>Tryon, 1863</small><ref name ="Davis 1979"/> * ''Pomatiopsis californica'' <small>Pilsbry, 1899</small><ref name ="Davis 1979"/> * ''Pomatiopsis chacei'' <small>Pilsbry, 1937</small> * ''Pomatiopsis cincinnatiensis'' <small>(Lea, 1840)</small><ref name ="Davis 1979"/> * ''Pomatiopsis hinkleyi'' <small>Pilsbry, 1896</small> * ''Pomatiopsis lapidaria'' <small>(Say, 1817)</small> - type species<ref name ="Davis 1979"/>
== Ecology == Species in the genus ''Pomatiopsis'' are amphibious, living in humid habitats, on marshy ground and in periodically flooded soil (''Pomatiopsis californica'' and ''Pomatiopsis lapidaria''), in trickling water (''Pomatiopsis binneyi'') and on mud of streams (''Pomatiopsis cincinnatiensis'').<ref name ="Davis 1979"/>
