The Lord Howe Long-eared Bat differs from all other members of the genus and its generic status needs re-examination (Parnaby 2009).

The Lord Howe Long-eared Bat is known only from an incomplete skull found in Gooseberry Caves on Lord Howe Island in 1972 (McKean 1975). The skull dimensions indicate that the species was the largest of the long-eared bats (Duncan et al. 1999), however, other morphological characteristics of the species are not known.

This species was confined to Lord Howe Island and most likely existed primarily within the Lord Howe Island National Park (Duncan et al. 1999).

Following the discovery of the skull, numerous surveys have been carried out in an attempt to identify extant individuals of this species. Les Hall carried out a search of all caves at North Head, which did not yield any living animals or remains and Glen Hoye conducted an extensive survey using traps and mist nets, which also failed to capture any individuals (Duncan et al. 1999).

The threat which caused the extinction of the Lord Howe Long-eared Bat is thought to be predation by introduced species (Duncan et al. 1999).

Further effort should be made to discover further material of the Lord Howe Long-eared Bat, including post-cranial material, from cave deposits on Lord Howe Island (Parnaby 2009). If the species is found to be extant in the future, the following recovery actions have been identified (Duncan et al. 1999):

  • Determine population size and abundance.
  • Determine ongoing threatening processes.
  • Identify the behaviour that governs roost and maternity site selection.
  • Review conservation status as appropriate.

The following table lists known and perceived threats to this species. Threats are based on the International Union for Conservation of Nature and Natural Resources (IUCN) threat classification version 1.1.
