Randrianasolo's sportive lemur (Lepilemur randrianasoloi), or the Bemaraha sportive lemur, is a sportive lemur endemic to a small area of western Madagascar. It is threatened by habitat loss.[1]
Taxonomy and phylogenetics
[edit]Randrianasolo's sportive lemur was originally described in 2006 as L. randriansoli, in honor of the Malagasy researcher Georges Randrianasolo.[4] However, the name was misspelled and was corrected to L. randrianasoloi in 2009.[5] The original 2006 description was entirely online, and therefore did not meet the pre-2012 ICZN standards to be a valid name.[6] It was therefore given a follow-up description in 2017.[3]
Genetic analyses show Randrianasolo's sportive lemur to be sister to the Antafia sportive lemur.[7]
Description
[edit]Randrianasolo's sportive lemur differs from all other members of genus Lepilemur, except the antafia sportive lemur and the red-tailed sportive lemur, by its number of chromosomes (2N=40). It differs from the other two species by its slightly smaller size, narrower but longer head, and cytochrome b sequence. Additionally, the hind feet are longer than in the red-tailed sportive lemur.[4][3]
It has a total length of about 49 to 56 cm (19 to 22 in), of which 21–26 cm (8.3–10.2 in) is the tail.[8]
Distribution and habitat
[edit]Randrianasolo's sportive lemur inhabits dry deciduous forests in a small region of western Madagascar. Known localities include Andramasay forest, Tsingy de Bemaraha National Park and a few other nearby forest fragments. It is estimated to occupy less than 2,200 km2 and is found between 47 and 139 metres above sea level.[1]
It has been proposed that the natural northern and southern limits of the species's range are the Manambolo river and Tsiribihina river, respectively.[4][3] However, this has not been tested empirically.[1]
Threats
[edit]The most pressing threat to Randrianasolo's sportive lemur is the clearing of forests within its range for agriculture and timber extraction.[1] Additionally, an 87% reduction in this species's range is expected by 2080 due to climate change alone.[9]
