Oromana Tubuaia Snail (Tubuaia voyana ssp. oromanaensis)
The Oromana Tubuaia Snail was described in 1962; it was only ever known from its type locality, the Oromana Hills on the island of Rimatara in the Austral archipelago, a place that today is completely degraded and transformed into agricultural fields (like actually most of the island).
This snail is now clearly extinct. [1]
