Subspecies and Distribution.
N.m.melanotisS.Miller,1840—WJava.
N.m.bancanusLyon,1906—BangkaI,Indonesia.
N.m.borneanusLyon,1906—Borneo,andLautI(offSEBorneo).

Descriptive notes. Head—body mean 79-6 mm (males) and 79 mm (females), tail mean 62 mm (males) and 70-5 mm (females); weight mean 17 g. Dorsum of the Black-eared Squirrel is plain pale agouti, with a black stripe from nose to eye; a broad bufly stripejust below black stripe extends to a buffy patch behind eye, and a second thin black stripe below buffy stripe extends to mouth. These stripes differentiate the Black-eared Squirrel from species of Exilisciurus. Back of ear and patch of fur just behind it are black. Subspecies melanotis has darker pelage than the other subspecies, dorsum is orange-brown and venteris pale orange-brown. Nape of neck is lighter brown than crown. Subspecies bancanus has yellow brown pelage, a distinct nape patch, and a buffy facial stripe. Subspecies borneanus has yellow brown pelage; a nape patch is present, although darker and less distinctive than pulcher. Facial stripe is whitish and slightly tinged with buffy. Subspecies pulcheris very similar to bancanus, although bancanus has darker pelage. Pelage is yellow brown with a distinct nape patch and whitish facialstripe.
Habitat. Lowland dipterocarp forests, up to elevations of ¢.1070 m.
Food and Feeding. The Black-eared Squirrel is a bark gleaner.
Breeding. There is no information available for this species.
Activity patterns. The Black-eared Squirrel is mostly seen on tree trunks and major branches due to its foraging behavior.
Movements, Home range and Social organization. There is no information available for this species.
Status and Conservation. Classified as Least Concern on The IUCN Red List. The Blackeared Squirrel is widespread and abundant in suitable habitat. Although it prefers primary forest, it is also known to occur in secondary and selectively logged forest. It is threatened by habitat loss due to logging and agricultural conversion, though this is not a major threat.
