Tupaiidae

The Tupaiidae are one of two families of treeshrews, the other family being Ptilocercidae. The family contains three genera and 19 species.[1] The family name derives from tupai, the Malay word for treeshrew and also for squirrel which the Tupaiidae superficially resemble. The former genus Urogale was disbanded in 2011 when the Mindanao treeshrew was moved to Tupaia based on a molecular phylogeny.[2]

Unlike shrews, they contain a fairly large brain for their size. While some research has found tree shrews as the closest living relative to primates, most molecular studies currently find the flying lemurs (colugos) as the sister group to primates despite their gliding specializations.[3]

Taxonomy

Conservation

A majority of the species,71.4%, in this family are of least concern, according to the IUCN red list. Nearly a twentieth of the species,4.8%, are vulnerable and the same number are endangered. 19% of the species have not had enough data collected yet for them to be rated on the scale.[4]
