Logo: Gliding mammals of the world

The world’s gliding mammals are an extraordinary group of animals that have the ability to glide from tree to tree with seemingly effortless grace. There are more than 60 species of gliding mammals including the flying squirrels from Europe and North America, the scaly-tailed flying squirrels from central Africa and the gliding possums of Australia and New Guinea.

Petaurillus emiliae

Order: Rodentia
Family: Sciuridae, Pteromyini

Description: A very small gliding squirrel, similar to Hose’s Pygmy Flying Squirrel, but even smaller. Its cheeks are entirely pale buffish without grey below its eyes.

Its colouration is very like that of Hose’s Pygmy Flying Squirrel but its fur is paler rufous on the back, with the tips of the hairs near vinaceous-cinnamon, and its belly is pure white. Its cheeks are a pale buff colour and there is no perceptible darker line below the eye.

Distribution: Known only from the type locality in the Baram District, eastern Sarawak on Borneo, where an adult male and female were collected in 1901 by the colonial administrator, zoologist and ethnologist Dr Charles Hose.

Reproduction: Nothing is known.

Diet: Nothing is known.

Ecology: Nothing is known.

Status: Least Concern.
