The Betsileo sportive lemur (Lepilemur betsileo) is a sportive lemur endemic to Madagascar. Like all members of its genus, it is nocturnal and largely folivorous. [3] It is threatened by habitat loss. [1]

Taxonomy and phylogenetics

The Betsileo sportive lemur was described in 2006 based on genetic samples and morphometrics collected in 2000 and 2004. The specific epithet betsileo is in reference to the Betsileo people. [4] Genetic analyses show that the Betsileo sportive lemur is a sister species to James' sportive lemur. [5]

Description

The Betsileo sportive lemur is predominantly grayish to reddish-brown, with the back darker than the underside. The tail is black, contrasting sharply with the rest of the body. The lower face below the mouth is white, while the rest of the face is gray. The fur in the ear auricle is light and bordered by dark hairs along the outer edge. [3] [4]

The species is relatively large. The head-body length measures 25 cm and the tail length is 28 cm, which combined together gives a total length of 53 cm. It weighs 1.1-1.2 kg. [3] [4]

Distribution and habitat

The Betsileo sportive lemur is only known from the Fandriana region of central-eastern Madagascar. While the northern and southern limits of its range have yet to be identified, they are suspected to be the Mangoro/Onive and Namorona rivers, respectively. [4] Using niche modeling, a 2018 study estimated the species to occupy 1,167 km2 and have a population size of approximately 2,315 individuals. [6] Within its range, it inhabits rainforests. [3]

Threats and conservation

The main threats to the Betsileo sportive lemur is habitat loss due to agricultural practices, use and modification of biological resources, and unsustainable levels of hunting. [1] The only protected area in which it is known to be present is the Bemosary Classified Forest in the Fandriana-Vondrozo Corridor. [3]

<span class="mw-page-title-main">Sportive lemur</span> Genus of lemurs

The sportive lemurs are the medium-sized primates that make up the family Lepilemuridae. The family consists of only one extant genus, Lepilemur. They are closely related to the other lemurs and exclusively live on the island of Madagascar. For a time, this family was named Megaladapidae, but the current name was given precedence since the extinct genus Megaladapis was removed from the family.

<span class="mw-page-title-main">Weasel sportive lemur</span> Species of lemur

The weasel sportive lemur, also known as the greater sportive lemur, weasel lemur, or greater weasel lemur, is a species of lemur endemic to Madagascar. Like all members of its genus, it is nocturnal and largely folivorous. Described by Isidore Geoffroy Saint-Hilaire in 1851, it is the type species of genus Lepilemur. It is threatened by habitat loss, climate change and hunting.

<span class="mw-page-title-main">Small-toothed sportive lemur</span> Species of primate from Madagascar

The small-toothed sportive lemur, or small-toothed weasel lemur, is a primate species in the family Lepilemuridae that—like all extant lemurs—is endemic to Madagascar. The species lives in dense rainforest in southeastern Madagascar, and can be found in Ranomafana and Andringitra National Parks. Described in 1894, it was considered either a subspecies or taxonomic synonym of the weasel sportive lemur throughout most of the 20th century. Phylogenetic studies not only support its species status, but also suggest that it is the only eastern Malagasy sportive lemur that is more closely related to western than to other eastern species.
