The grand roundleaf bat (Hipposideros grandis), also known as the grand leaf-nosed bat, is a species of bat in the genus Hipposideros. It can be found in China, Myanmar, Thailand, and Vietnam.
Per George Henry Hamilton Tate, it was described as a new taxon in 1936 by American zoologist Glover Morrill Allen.[1] [2] Allen listed it as a subspecies of the intermediate roundleaf bat (Hipposideros larvatus). The holotype was collected in Chindwin, Myanmar.[1] It was frequently listed as a subspecies until 2006, when analyses of its echolocation and morphology demonstrated that the grand roundleaf bat is distinct enough to be considered a full species.[3]
Males have a mean forearm length of, while females have a mean forearm length of . Males weigh, while females weigh . In India, the species has a peak echolocation frequency of 98 kHz, which helps distinguish it from other Hipposideros species.[3]
This species is found in several countries in Asia, including China, Myanmar, Thailand, and Vietnam. It is also found in India.[3]
As of 2016, it is evaluated as a least-concern species by the IUCN. It meets the criteria for this classification because it has a wide geographic range, it is relatively abundant in Vietnam, and it tolerates some human disturbance to its habitat.
