Karyotype of the African Small-Eared Dormouse (Graphiurus microtis) from Nganda (Nyika Plateau, Malawi) consisted of 2n=52 chromosomes: 11 pairs of metacentrics, 14 pairs of acrocentrics and subtelocentrics, the X-chromosome being a metacentric, Y-chromosome a small acrocentric. It represents a new karyotype reported for African dormice (Graphiurinae). Regarding the scarity of data (thus far karyotypes of only four species representing five populations, including the present data, out of currently recognized 13–14 species, distributed throughout Sub-Saharan Africa have been described) it is worth of being published but any efforts to derive conclusions regarding chromosomal speciation in graphiurines would be preliminary and speculative.
