Pseudamnicola singularis Letourneux & Bourguignat

Singular Pseudamnicola Snail (Pseudamnicola singularis)

The Singular Pseudamnicola Snail was described in 1887, it was apparently restricted to two localities; one somewhere near the village of Oudhref and the second one near Gabès, the capital city of the Gabès Governorate, both in Tunisia.

The species was never found again since its description and appears to be extinct.
