The revision of Graphiurus by Genest-Villard (1978), based mostly on size grades, underestimated species diversity, particularly in the G. murinus group. Subsequently, species limits were defined in reports covering different African regions (e.g., Ansell and Dowsett, 1988; Holden, 1996b; Robbins and Schlitter, 1981) The species recognized below reflect information in the literature, as well as myexamination of museum specimens and preliminary, mostly unpublished multivariate analyses of cranial and dental measurements.
