Light-necked Sportive Lemur

The small-toothed sportive lemur (Lepilemur microdon), 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 (Lepilemur mustelinus) 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.
According to the original description, some of its teeth are smaller than those in other sportive lemurs. It is relatively large for a sportive lemur, and is difficult to visually distinguish from the weasel sportive lemur. The species weighs between 0.9 and 1.2 kg (2.0 and 2.6 lb) and measures 55 to 64 cm (22 to 25 in) from head to tail. Its fur is mostly reddish-brown or chestnut color, with a dark stripe running from its head down its back. Its underside and neck are lighter in color. Like other sportive lemurs...
