Partula taeniata, common name the Moorean viviparous tree snail, is a species of terrestrial gastropod in the Partulidae family.

[1] This species was considered to be extinct in the wild, but intensive field surveys have recently detected surviving wild populations.

[1] Previously it was incorrectly listed as extinct on the IUCN Red List of Threatened Species from 1988 to 1994[1] and as Extinct in the wild in the 1996 IUCN Red List, before being corrected to Critically Endangered in 2009,[3] although two subspecies survive in captivity and one still exists in the wild.

[4] This error may be the result of changing taxonomy (the subspecies were previously considered to be separate species).

simulans was transferred to the Edinburgh Zoo; the subspecies now has several hundred individuals surviving in captivity.
