Year Assessed: 2008
Assessor/s: Maeda, K.
Reviewer/s: Hutson, A.M., Racey, P.A. (Chiroptera Red List Authority) & Chanson, J. (Global Mammal Assessment Team)
Justification:
This species is listed as Data Deficient as it is known only from the holotype of unknown provenance, which may or may not be from Japan. There is doubt about the taxonomic status, as well as the distribution of this species. Previously incorrectly presumed Extinct based on the assumptions about its distribution and taxonomic status.
History:
2006 – Data Deficient (IUCN 2006)
2000 – Extinct
1996 – Endangered
1994 – Extinct (Groombridge 1994)

Geographic Range [top]

Range Description: Pipistrellus sturdeei is known only from Hahajima Island in the Bonin (= Ogasawara) Islands, Japan (Abe 2005). Some experts believe that this bat never actually occurred in Japan, and that the type locality is in error (Abe 2005). Therefore, the true distribution and country of origin are unknown.
Countries:
Presence uncertain:
Japan (Ogasawara-shoto)

Population [top]

Population: Unknown. Only the type specimen presumably collected at the end of the 19th century is preserved (housed in the British Museum of Natural History) (Abe 2005), and there have been no further records for over a century.
Population Trend: Unknown

Habitat and Ecology [top]

Habitat and Ecology: Unknown.
Systems: Terrestrial

Threats [top]

Conservation Actions [top]

Conservation Actions: There is a need to confirm the taxonomic validity of this species. If this is a valid species, there needs to be research into its actual distribution and whether there are any extant populations. It is listed as Data Deficient (DD) in the Japanese Red List (2007).
