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 kHz. 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]

The Indian roundleaf bat, also known as the large Ceylon leaf-nosed bat or Kelaart's leaf‐nosed bat is a species of bat in the family Hipposideridae. It is endemic to the Indian subcontinent, with marginal populations also detected in Southeast Asia. Its natural habitats are subtropical or tropical dry forests and caves. The bat has three subspecies that occur in India, Sri Lanka, and Myanmar. The Indian subspecies, H. l. indus, is smaller than the ones found in Sri Lanka and Myanmar, although there are no other characteristics that differentiate the subspecies.

<span class="mw-page-title-main">Bicolored roundleaf bat</span> Species of bat

The bicolored roundleaf bat is a species of bat in the family Hipposideridae found in Indonesia, Malaysia, Singapore, the Philippines, Thailand, and Timor-Leste. This bat inhabits caves, rock crevices and tunnels among lowland forests. They roost in large numbers and consume mostly small winged insects. Their navigation and hunting skills come from the use of echolocation. Its leafnose is used to release ultrasonic shouts to distinguish its surroundings. Echolocation is also used to distinguish other species based on their wingbeat and size. The habitat of this bat decides the color of its fur. Bleaching fumes of a cave environment will cause an orange colored fur. Those who inhabit a well-ventilated roost will be a light brown color.
