Bythinella limnopsis Letourneux & Bourguignat

Kairouan Spring Snail (Bythinella limnopsis)  

This species, whose taxonomical classification cannot be completely resolved, was found only at two places in Tunisia, in several springs near the town of Qairawan, as well as in the basin of an ancient Roman Spring Sanctuary near the town of Zaghouan.  

The species was last seen in 1887, and has not been found since, despite several surveys, and is now considered extinct.
