Kalimantan Treeshrew Tupaia salatana French: Toupaye du Kalimantan / German: Kalimantan-Spitzhérnchen / Spanish: Tupaya de Borneo Taxonomy. Tupaia longipes salatana Lyon, 1913 , “Pangkallahan River, S. E. Borneo, 15 miles [= 24 km] from mouth,” Indonesia . Tupaia salatana was historically considered an island population of 7. glis . Recent morphological work recognized differences between specimens from Borneo (now containing T. longipes and 1. salatana) and 1. glis . Fine-scale morphological evaluation by E. J. Sargis and colleagues in 2012 elevated the once subspecies salatana to a distinct species. Monotypic. Distribution. S Borneo, S of the Rajang and Kayan rivers. Descriptive notes. Head-body 175-210 mm, tail 175-205 mm, hindfoot 50-53 mm. No specific data are available for ear measurements or body weight. The Kalimantan Treeshrew is quite similar in appearance to the Long-footed Treeshrew (7. longipes ), with only slightly different pelage. Pelage of the Kalimantan Treeshrew is slightly more reddish, and shoulder marking also appears more red. Length of hair on the Kalimantan Treeshrew is slightly longer. There is dark saddle on underparts at mid-abdomen; remaining ventral fur is tan anteriorly and ivory posteriorly. Tail has longer hair at base that shortens at tip. Habitat. Presumably found in lowland forests in Southern Sarawak and Kalimantan. Food and Feeding. No information. Breeding. No information. Activity patterns. There is no information available for this species, but the Kalimantan Treeshrew is presumably diurnal. Movements, Home range and Social organization. No information. Status and Conservation. CITES Appendix II. Classified as Least Concern on The IUCN Red List. The Kalimantan Treeshrew has probably undergone declines due to ongoing forest loss, particularly at low elevations; these declines during the past ten years are probably not large enough to warrant listing in a threatened category.
