n viviparous tree snail Partula taeniata is a species
of gastropod in the Partulidae
family. It is endemic to French Polynesia
.
This species was considered to be extinct in the wild, but intensive field surveys have recently detected surviving wild populations.
in the 2011 IUCN Red List of Threatened Species.
Previously it was incorrectly listed as extinct in the 2007 IUCN Red List of Threatened Species and as Extinct in the wild
in the 2009 IUCN Red List,although two subspecies
survive in captivity and one is still extant. This error may be the result of changing taxonomy
(the subspecies have been considered separate species before).
