|Scientific Name:||Nyctophilus howensis McKean, 1975|
|Taxonomic Notes:||In describing the species, McKean (1975) provisionally placed it with Nyctophilus, but the generic status of the species requires re-evaluation because it might not belong with Nyctophilus (H. Parnaby pers. comm.).|
|Red List Category & Criteria:||Critically Endangered (Possibly Extinct) D ver 3.1|
|Assessor(s):||Hall, L., Lumsden, L. & Parnaby, H.|

Listed as Critically Endangered (Possibly Extinct) because, although this species is only known from a single skull found in 1972 and extensive surveys have failed to locate it since, islanders continue to report seeing two different sized bats. There is only one other bat species known from Lord Howe Island, such that these recent sightings raise the possibility that this species is not extinct. Were the species to be found, its population would almost certainly be less than 50 individuals.
|Date last seen:||1972|
|Previously published Red List assessments:|
|Range Description:||This species is endemic to Lord Howe Island, New South Wales, Australia.|
|Range Map:||Click here to open the map viewer and explore range.|
|Population:||It is known only from an incomplete skull that was considered to be a sub-fossil until a recent re-examination indicated that it was from the 20th century (Richards 2008).|
|Current Population Trend:||Unknown|
|Habitat and Ecology:||The only known specimen (an incomplete skull) was collected from a ledge in a cave that may have been an owl roost (Duncan et al. 1999).|
|Major Threat(s):||The reasons for its decline are unclear, however, it is possible that this species was predated by introduced owls and rats.|
Introduced owls have now been eradicated from Lord Howe Island and programmes to eradicate rats are underway (Duncan et al. 1999).
Extensive surveys for this species have not located any remaining animals (Duncan et al. 1999). Contemporary reports by locals, however, of two sizes of bats flying at dusk, the larger currently unidentified (N. Carlile pers. comm.), indicates the need for further survey work. If it were found to be extant, further studies would be needed into the abundance, natural history, and threats to this species.
