About the Grand Leaf-nosed Bat

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.

Allen listed it as a subspecies of the intermediate roundleaf bat (Hipposideros larvatus). The holotype was collected in Chindwin, Myanmar. 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.

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.

This species is found in several countries in Asia, including China, Myanmar, Thailand, and Vietnam. It is also found in India. As of 2016, it is evaluated as a least-concern... Wikipedia →
