The Sunda flying lemur (Galeopterus variegatus), also known as the Malayan flying lemur, is a species of colugo (see below for notes on the common name "flying lemur"). Until recently, it was thought to be one of only two species of flying lemur, the other being the Philippine flying lemur which is found only in the Philippines. The Sunda flying lemur is found throughout Southeast Asia in Indonesia, Thailand, Malaysia, and Singapore.The Sunda flying lemur is protected by national legislation. In addition to deforestation and loss of habitat, local subsistence hunting poses a serious threat to this animal. Competition with the plantain squirrel (Callosciurus notatus) represents another challenge for this species. More information is needed on population declines, but at present the rate of the decline is believed to be probably not fast enough to trigger listing in any category other than Least Concern.
