Data Deficient (IUCN 3.1)|Data Deficient
The small-toothed sportive lemur (Lepilemur microdon), or small-toothed weasel lemur, is a primate species in the family Lepilemuridae that—like all lemurs—is endemic to Madagascar. The species lives in dense rainforest in southeastern Madagascar, and can be found in Ranomafana National Park and Andringitra National Park. As its name implies, 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, it is nocturnal, sleeping in concealed tangles of vegetation as well as tree holes. The small-toothed sportive lemur is solitary and eats leaves, fruits, and flowers. Due to recent taxonomic changes and a lack of clarity about its population size and range, it is listed as "Data Deficient" by the International Union for Conservation of Nature (IUCN). It is also protected from international commercial trade under CITES Appendix I. Its primary threats are habitat loss to slash and burn agriculture and hunting.
