land of Sulawesi (Indonesia), in areas with elevations no
higher than 100 m in the coastal lowlands around the central
mountains and fringing the northwestern margin of the bay
(Teluk Bone) in the southeastern part of the island. This spe-
cies’ total distribution is unknown.geographic variation: None.conservation: IUCN status—data defi cient. Population
trend—no information.habitat: Little is known, but collection localities indicate
that its habitat is tropical lowland evergreen rainforests.natural history: Nothing is known about the natural
history of P. weberi. Due to its morphological similarity to P.
topapuensis and P. alstoni, however, it is conjectured that P.
weberi lives in the upper canopy and eats soft fruits, seeds,
and insects.general references: Musser et al. 2010.Rhinosciurus Blyth, 1856
