This species was considered to be extinct in the wild, but intensive field surveys have recently detected surviving wild populations.[2]
Conservation status
The species is listed as Critically Endangered in the 2022 and 2024 IUCN Red List of Threatened Species.[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).
In 2010, a single Partula taeniata spp. simulans was transferred to the Edinburgh Zoo; the subspecies now has several hundred individuals surviving in captivity.[5]
Subspecies
Listing of subspecies in the 2011 IUCN Red List of Threatened Species (not up to date):
