This is the 'large aquatic' species of the middle and northern springs in the Lake Eyre supergroup. It has a larger shell than F. accepta. The operculum has rather weak to moderately strong pegs, or they are sometimes absent.

This is the large aquatic species living in the Middle, South Western, Northern and Freeling Springs. It is generally abundant in the pool at the head of the springs. It can sometimes be seen clustering on the sides of the outflows but it is not amphibious and, if emergent, is covered by a film of water. Lives together with Trochidrobia.

This is one of several species of Fonscochlea found in northern South Australia. They are all very similar, being separated on small differences in size and shape of the shells and in anatomical details. They have pupiform shells with adults having a thin to slightly thickened aperture and the operculum usually bears one or more pegs. Fonscochlea are among the most geographically isolated tateid snails in Australia.
