Hipposideros sp. ‘New Caledonia’

New Caledonian Roundleaf Bat (Hipposideros sp.)

The New Caledonian Roundleaf Bat is known from subfossil remains that were recovered from Holocene deposits in the Mé Auré Cave near the southern shore of Grande Terre, New Caledonia.

The remains were compared to the bones of several other congeneric species from the nearest regions but did not match to any of them, thus it most likely was a distinct species that might well have been endemic to New Caledonia. [1]

Besoaka Roundleaf Bat (Hipposideros besaoka)

The Besoaka Roundleaf Bat was described in 2007 based on subfossil remains that were recovered from deposits in the Grotte d’Anjohibe in the former Mahajanga Province in northern Madagascar.

The species was closely related to the recent Commerson’s Raoundleaf Bat (Hipposideros commersoni (E. Geoffroyi)) (see photo below) and both species apparently lived sympatrically.

The Besoaka Roundleaf Bat seems to have disappeared at the beginning of the Holocene.
