Habitat:
The Loyalty Bent-winged Bat is a colonial cave-roosting species that roosts with both Very little is known of the species ecology. It is currently known from Pregnant females have been captured in October 2001 (Kirsch et al. 2002). The biometrics of the species are: Length Head Body: male 44-46 mm, female 43-49 mm; Tail: male 37.5-43.5 mm, female 42-46 mm; Forearm: male 39.5-40.5 mm, female 39-42.2 mm; Tibia: male 15-15.8 mm, female 14.3-15.2 mm; and Ear: male 11.5-12.2 mm, female 12-13 mm (From Revilliod 1914 and Flannery 1995).

Range:
The Loyalty Bent-winged Bat has the smallest distribution of other Miniopterus species and is known only from the islands of Lifou and Maré in the Loyalty Islands of New Caledonia (Flannery 1995). The species range is severely fragmented on Lifou and Maré in the Loyalty Islands of New Caledonia (two subpopulations; two locations). Its area of occupancy (AOO) is calculated as 28 km² (using the 2 x 2 km grid approach) at the seven (7) known cave roosts where the bats are most at risk as they spend approximately half of their lives in the roosts. Its extent of occurrence (EOO) is 4,422 km².

Conservation:

It is not known if the Loyalty Bent-winged Bat is present in any protected areas. The known cave-roosts need effective long-term protection and restoration, both of the cave system and habitat in the surrounding area to ensure they are not lost or degraded further. Human visitation should be carefully controlled or even restricted depending on the configuration of the caves. Robust monitoring of the species and its habitat is warranted and invasive species should be controlled and eradicated if possible. Further studies are required into the distribution, ecology, possible threats, and current status of this species.
