Description

A small species, this dormouse has a head-and-body length of and a tail of . The fur on the back is soft, smooth and rather long. The dorsal colour varies, ranging from golden brown, rusty brown or drab brown to dark brown, the ridge of the back often being darker than the rest. The underparts are white or cream, slightly tinted with grey, and there is a sharp line demarcating the junction between the dorsal and ventral colouring. The ears are large, brown and rounded and the eyes are large. There is a conspicuous mask round the eyes and the cheeks are white or cream, this colour extending in a band to the shoulders. The tail has short fur near the base and long hair near the tip. It is basically the same colour as the dorsal fur but some white hairs are mixed with the darker ones and the tip is white. This species is similar in appearance and skull characteristics to the rock dormouse (''Graphiurus platyops'') but their distributions do not overlap. The stone dormouse (''Graphiurus rupicola'') is larger and not found in

woodland, and the small-eared dormouse (''Graphiurus microtis'') is smaller and the ranges of the two species only overlap in Zambia.

Distribution and habitat

The known species range includes only northern and central Angola and western Zambia, at altitudes between about . It has only been recorded from seven locations and is likely an uncommon species, its typical habitat being tropical dry woodland, and wooded savannah. In

woodland it tends to occur in the vicinity of water.

because of its dubious taxonomic status, the lack of knowledge as to the extent of its occurrence and its conservation status, and the lack of information on its life cycle and the threats it faces.
