Lesser Pygmy Flying Squirrel (Petaurillus emiliae)

The Lesser Pygmy Flying Squirrel was described in 1908 based on a single specimen that was collected in 1901 in Sabah, northern Borneo.

It is the smallest of the three species within its genus, reaching a full size of about 14 cm (including the tail).

The species was never found since its description and, probably being restricted to intact forest habitats, may now be extinct since large areas in the region have been converted into oil palm plantations.
