Hylopetes platyurus (Jentink, 1890)
Jentink’s Flying Squirrel
description: Taxonomically confused with H. spadiceus
and H. lepidus in the past, H. platyurus is distinctly smaller in
its overall body dimensions and in at least 21 craniodental
measures than these other two species. In H. platyurus the
cheeks and the base of the tail are gray, as compared with
those of H. spadiceus and H. lepidus, which are more pinkish,
although overlap occurs between the three species. The tail
of H. lepidus is also shorter and narrower than that of the
other two species.
size: Female—HB 130.0 mm; T 100.0 mm.
distribution: Jentink’s fl ying squirrel is found only in
northern Sumatra (Indonesia), peninsular Malaysia, and the
island of Borneo (divided among Malaysia, Brunei Darus-
salam, and Indonesia). Neither the South China Sea nor the
Malacca Strait has been a barrier for H. platyurus.
geographic variation: None.
conservation: IUCN status—data defi cient. Population
trend—no information.
habitat: Little is known about this species’ preferred habi-
tat. It is reported from rubber forests, forest edges, and near
human activities; however, it has not been observed in pri-
mary forests.
natural history: Little is known about the distribution,
ecology, and behavior of this species.
