L. manasamody Craul et al., 2007 Grewcock's sportive lemur (Lepilemur grewcockorum), or the Anjiamangirana sportive lemur, is a sportive lemur endemic to Madagascar.

[4] Grewcock's sportive lemur is found in northwestern Madagascar, living in dry deciduous forests.

[4] Originally named L. grewcocki, the name was found to be incorrectly formed and was corrected to L. grewcockorum in 2009.

[5] It was also found to be synonymous with the Manasamody sportive lemur (Lepilemur manasamody),[5][6] known for its primarily grey-brown coloration and known only from Ambongabe and Anjiamangirana I (between the Sofia River in the south and the Maevarano River in the north).

[7] The decision was made because the sampling sites were within 2 km (1.2 mi) of each other, and no geographic barrier could be identified.
