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.

Taxonomy

Per George Henry Hamilton Tate, it was described as a new taxon in 1936 by American zoologist Glover Morrill Allen.^[2][3] Allen listed it as a subspecies of the intermediate roundleaf bat (Hipposideros larvatus).^[4] The holotype was collected in Chindwin, Myanmar.^[2] 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.^[4]

Description

Males have a mean forearm length of 60.5 mm (2.38 in), while females have a mean forearm length of 61 mm (2.4 in). Males weigh 18.3 g (0.65 oz), while females weigh 17.6 g (0.62 oz). In India, the species has a peak echolocation frequency of 98 kHz, which helps distinguish it from other Hipposideros species.^[4]

Range and habitat

This species is found in several countries in Asia, including China, Myanmar, Thailand, and Vietnam.^[1] It is also found in India.^[4]

Conservation

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.^[1]
