Rousettus celebensis

The Sulawesi rousette or Sulawesi fruit bat (Pilonycteris celebensis) is a species of megabat in the family Pteropodidae endemic to Sulawesi, an island in Indonesia. It is presently the only member of the genus Pilonycteris.

Taxonomy

It was formerly classified in the genus Rousettus until 2021, when a phylogenetic study found it to belong to its own genus (and tribe, although a new tribe was not described for it) that was more derived than Rousettus, which was described as Pilonycteris. P. celebensis is thought to be the only member of Pilonycteris, but Rousettus linduensis may also belong. [2] [3]

Description

The tibia of the Sulawesi rousette bat is covered in dense fur. Its antitragal lobe is fairly reduced. The bony arch of its cheek is narrow and triangular in shape. The male's distal end of the penis has a flattened and triangular shape. [4]

Diet

Rousettus celebensis is a fruit-eating bat; it has big wings which allow it to carry heavy loads and also make it a good seed disperser. Its diet consists of large seeds, an uncommon feature, compared to other frugivorous bats. R. celebensis has a unique digestive system which allows it to digest certain seeds or seed coats or both. [5]

<span class="mw-page-title-main">Megabat</span> Family of fruit bats

Megabats constitute the family Pteropodidae of the order Chiroptera (bats). They are also called fruit bats, Old World fruit bats, or—especially the genera Acerodon and Pteropus—flying foxes. They are the only member of the superfamily Pteropodoidea, which is one of two superfamilies in the suborder Yinpterochiroptera. Internal divisions of Pteropodidae have varied since subfamilies were first proposed in 1917. From three subfamilies in the 1917 classification, six are now recognized, along with various tribes. As of 2018, 197 species of megabat had been described.

<i>Cynopterus</i> Genus of bats

Cynopterus is a genus of megabats. The cynopterine section is represented by 11 genera, five of which occur in Malaysia, namely, Chironax, Balionycteris, Penthetor, Dyacopterus, and Cynopterus. About 30 names for Cynopterus species have been proposed, but only 16 are taxonomically valid forms.

<i>Rousettus</i> Genus of bats

Rousettus is a genus of Old World fruit bats or megabats, referred to as rousette bats. The genus is a member of the family Pteropodidae. The genus consists of seven species that range over most of Africa to southeast Asia, and the islands of the south Pacific. They are among the few megabats capable of echolocation, and the only genus of megabats known to use vocal echolocation.

<span class="mw-page-title-main">Egyptian fruit bat</span> Species of bat

The Egyptian fruit bat or Egyptian rousette is a species of megabat that is found in Africa, the Middle East, the Mediterranean, and the Indian subcontinent. It is one of three Rousettus species with an African-Malagasy range, though the only species of its genus found on continental Africa. The common ancestor of the three species colonized the region in the late Pliocene or early Pleistocene. The species is traditionally divided into six subspecies. It is considered a medium-sized megabat, with adults weighing 80–170 g (2.8–6.0 oz) and possessing wingspans of approximately 60 cm (24 in). Individuals are dark brown or grayish brown, with their undersides paler than their backs.
