Two species of Hylopetes, a genus of small flying squirrels native to Southeast Asia, found in the island of Java, Indonesia: (1) narrow-tailed flying squirrel (Hylopetes sagitta) and Bartel’s flying squirrel (Hylopetes bartelsi). The arrow-tailed flying squirrel (Hylopetes sagitta) (Sciuridae, Rodentia) is endemic to the islands of Java (H. s. sagitta Linnaeus, 1766) and Bangka (H. s. aurantiacus Wagner, 1841). The original specimen described by Linnaeus (1766) was named Sciurus sagitta and placed in Hylopetes by Chasen (1940), including Pteromys lepidus (Horsfield, 1824) and H. sagitta aurantiacus as a subspecies. Ellerman & Morrison-Scott (1955) recognized these species as Hylopetes lepidus which included subspecies H.l. aurantiacus and H.l. platyurus. Medway (1977) separated Hylopetes lepidus and Hylopetes sagitta into different species. Then Rasmussen & Thorington (2008) considered these species to be Hylopetes lepidus, placed H. sagitta as a synonym, and included H.l. aurantiacus and but not H.l. platyurus.
