All species within family Planorbidae have sinistral shells.
Species of Isidorella may appear to be very similar species of Glyptophysa. However, Isidorella may differentiated by their lack of a stylet and an accessory structure. Isidorella also have a two-lobed penis, unlike Glyptophysa.[2]

Species edit
