The Sumatran Treeshrew occurs on Sumatra and Tanahbala in the Batu Islands. A 2011 survey recorded a field-identified Tupaia glis at a forest trap line in Riau, Sumatra.
It has a slight gray tint at the neck, a reddish wash across the middle of the body, and darker blackish-brown fur toward the rump. The underside is gray or tan, and a distinct shoulder marking is present.
In May 2011, a field-identified Tupaia glis was captured at trap line RA1105AC in Rama Rama Estate, Riau, Sumatra. The trap line is recorded as forest.
An extinction-risk assessment has not been added yet.
