Oudhref Pseudamnicola Snail (Pseudamnicola oudrefica)
The Oudhref Pseudamnicola Snail was described in 1887, it was apparently restricted to a place somewhere near the village of Oudhref in the Gabès Governorate, Tunisia.
This species has not been found since the 19th century and is now extinct.

I could not find any other information about this species so far, it appears that no one really cares for molluscs, let alone small to tiny ones.
