Other common names: Mentawai Treeshrew

Taxonomy. Tupaia chrysogaster G. S. Miller, 1903,

“North Pagi Island, [Mentawai Is- lands], Sumatra,” western Indonesia .

Recent morphological research deter- mined that 7. glis siberut from Siberut Is- land (another island in the Mentawai Islands) wasalso likely 7: chrysogaster, which was formerly included in the 7. glis complex but has since been elevated to a distinct species, as have many formsfrom this complex. Monotypic.

Distribution. Sipora and North and South Pagai Is, MentawaiIs; population on Siberut I likely belongs to this species.

Descriptive notes. Head-body 180-220 mm, tail 125-150 mm, ear 13-17 mm, hindfoot 43-45 mm. No specific data are available for body weight. The Golden-bellied Treeshrew is large; dorsum is uniform brown, with tinges of red; and venteris lighter, with tan hue. Tail has short hair, ¢.10 mm in length, and diagnostic light shoulder marking seen in many tupaiids is faint in some specimens and absent in others.

Habitat. [Lowland primary rainforests on four Mentawai Islands at elevations up to 1000 m.

Food and Feeding. There is no specific information available for this species, but the Golden-bellied Treeshrew is presumably a generalist based on cranial morphology.

Breeding. No information.

Activity patterns. There is no specific information available for this species, but the Golden-bellied Treeshrew is presumably diurnal.

Movements, Home range and Social organization. No information.

Status and Conservation. CITES Appendix II. Classified as Endangered on The [UCN Red List. The Golden-bellied Treeshrew is one of the two treeshrew species currently listed in this category.
