Hipposideros atrox, commonly known as the lesser bicolored leaf-nosed bat, is a species of bat found in Southeast Asia. Originally described as a subspecies in 1918, it was recognized as a full species in 2010. It uses echolocation to navigate and find prey, and roosts in caves during the day.
Taxonomy
Hipposideros atrox was described as a new subspecies of Hipposideros gentilis by Danish mammalogist Knud Andersen in 1918; [2] [1] he described H. gentilis in the same publication. The holotype had been collected by Arthur Lennox Butler in the Malaysian state of Selangor. [2] Hipposideros gentilis has been recognized as a synonym of the Pomona roundleaf bat (Hipposideros pomona). [3] In 1963, British mammalogist John Edwards Hill included H. atrox as a subspecies of the bicolored roundleaf bat (Hipposideros bicolor). [4] However, in 2010 H. atrox was recognized as a distinct species for the first time, [4] [5] which was followed by the IUCN in 2019. [1]
Description
H. atrox has a forearm length of 40.7–46.0 mm (1.60–1.81 in). Males have an average body weight of 6.6 g (0.23 oz) while females have an average body weight of 7.0 g (0.25 oz). [4]
Biology and ecology
It is an echolocating species of bat, using constant frequency echolocation. The frequency of maximum energy is approximately 142 k Hz. It roosts in sheltered areas during the day such as caves, which it cohabitates with other species of the genus Hipposideros [4]
Range and habitat
It is native to Southeast Asia where its range includes Malaysia, Indonesia, and Thailand. It has been documented at a range of elevations from 9–860 m (30–2,822 ft) above sea level. [1]
Conservation
As of 2019, H. atrox is considered a least-concern species by the IUCN. It meets the criteria for this designation because it has a wide geographic range; its population is presumably large; it tolerates human disturbance of the landscape; and it is not thought to be experiencing rapid population decline. [1]
