Scientific classification  | |
| Kingdom: | Animalia |
| Phylum: | Mollusca |
| Class: | Gastropoda |
| Superorder: | Hygrophila |
| Family: | Planorbidae |
| Genus: | Isidorella 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
Species
Species within this genus include:
- Isidorella bradshawi Iredale, 1943
- Isidorella egregia (Preston, 1906)
- Isidorella ferruginea (Adams and Angas, 1864)
- Isidorella hainesii (Tryon, 1866)
- Isidorella newcombi (A. Adams & Angas, 1864) - type species[3]
Walker (1988) considered all examined specimens from Australia from this genus as Isidorella newcombi sensu lato.[3]
Ecology
Isidorella snails are grazers-scrapers and are capable of aestivation.[2] Isidorella may be found in ponds, billabongs, swamps, and sluggish streams and rivers.
