Tate, 1896[1]

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]

Distribution

edit

This genus is endemic to mainland Australia.[3]

Species

Walker (1988) considered all examined specimens from Australia from this genus as Isidorella newcombi sensu lato.[3]

Isidorella snails are grazers-scrapers and are capable of aestivation.[2] Isidorella may be found in ponds, billabongs, swamps, and sluggish streams and rivers.
