Ridley's roundleaf bat, Singapore roundleaf horseshoe bat
Ridley's leaf-nosed bat has a forearm length of 47–51 mm (1.9–2.0 in). Its nose-leaf is very large and dark, covering its muzzle. The nose-leaf lacks lateral leaflets (smaller projections to the side).
It is found in Southeast Asia where it has been documented in Brunei, Malaysia, and Singapore. It is found at a range of elevations from 0–500 m (0–1,640 ft) above sea level. Its habitat is lowland old-growth forest. Possibly, its range also includes Indonesia.
As of 2020, it is evaluated as a vulnerable species by the IUCN. It met the criteria for this classification because predicted habitat loss from 2008–2018 meant that the species would likely experience a population reduction of more than 30%.
