Taxonomy. Lepilemur grewcocki Louis et al., 2006,
Madagascar, province of Mahajanga, Anjiamangirana Classified Forest, (¢. 15°09° 8,47° 43’ £).
In 2007, M. Craul and coworkers described L. manasamody from Ambongabe (15° 19’ 38.3" §, 46° 40’ 44-4” E) and Anjiamangirana (15 ° 09’ 24-6” S, 47° 44’ 06 -2” E) in the province of Mahajanga. D. Zinner and coworkers pointed out that same year that localities for this species and those for L. grewcockorum were only 2 km apart (the Anjiamangirana Classified Forest is the type locality for L. grewcockorum) and that there was no obvious biogeographical barrier between them. They suggested that manasamody was a junior synonym. A molecular genetic analysis by R. Lei and coworkers in 2008 subsequently confirmed this. Monotypic.
Distribution. NW Madagascar, from the Anjiamangirana region and forest fragments near Anjajavy and between Antsohihy and Analalava, N of the Sofia River and S of the Maevarano River; the range also includes the Bongolava Massif.
Descriptive notes. Head-body c.25 cm,tail 28-29 cm; weight 900 g. Similar to Milne-Edwards’s Sportive Lemur (L. edwardsi) but slightly smaller. The pelage is predominantly gray above and light gray to white below, with chocolate-mottled fur on the shoulders and along the sides of the body. A dark stripe is present on the midline of the crown, which may continue onto the back in some individuals. The area around the maxilla and the dorsal surface of the snout is whitish-pink, with whitish fur along the mandible that continues down the throat. The tail is usually entirely gray, but it can have a white tip of variable length—a characteristic found occasionally in Milne-Edwards’s Sportive Lemur and the Ambodimahabibo Sportive Lemur (L. otto). The ears are quite conspicuous, with short hairs on the dorsal surface, making them look almost pink.
Habitat. Dense primary forest fragments in mountainous and coastal areas of the southern Sambirano.
Food and Feeding. There is no specific information available for this species, but it is presumably largely folivorous.
Breeding. There is no information available for this species.
Activity patterns. Nocturnal and arboreal.
Movements, Home range and Social organization. This species has not been studied in the wild.
Status and Conservation. CITES Appendix I. Classified as Data Deficient on The IUCN Red List. However, at the IUCN/SSC Lemur Red-Listing Workshop held in July 2012, L. grewcockorum was assessed as endangered due to the high hunting pressure and the extent of habitat fragmentation in its small 1200 km? range. The Anjiamangirana Sportive Lemur is known to occur in the Anjiamangirana Classified Forest and a proposed 50,300ha conservation area on the Bongolava Massif. Encounter rates in forest fragments near Anjajavy and between Antsohihy and Analalava were low compared with those of other sportive lemur species.
