New specimens of <i>Acomys spinosissimusi> from northern Malawi and southern Tanzania were subjected to morphological, molecular (cytochrome <i>bi> mitochondrial gene) and cytogenetical analysis in order to establish the phylogenetic position of these populations among <i>A. spinosissimusi>, as well as their relationships with other species (<i>A. subspinosusi> and <i>A. wilsonii>). The monophyly of the <i>spinosissimusi> clade is supported by morphological and molecular phylogenies. Cytogenetics and morphology, but not the cytochrome <i>bi> phylogeny show the possible existence of two sibling species within <i>spinosissimusi>. Incongruences are noted between molecular and morphological trees, especially concerning the position of the Transvaal specimens. Two different biogeographic scenarios for the origin and dispersal of <i>A. spinosissimusi> are discussed in the light of available palaeontological data.
