Genus Hybomys Thomas, 1910

Species of Hybomys from the Cameroon volcanic line require taxonomic revision ( Musser & Carleton 2005). They all belong to the so-called Hybomys univittatus (Peters, 1876) species complex. Pending further molecular analyses, we keep the old nomenclature by recognizing H. eisentrauti Van der Straeten & Hutterer, 1986 from Mt Lefo and Oku, H. badius Osgood, 1936 from Mt Cameroon, and H. basilii Eisentraut, 1965 from Bioko at specific rank. In fact, Musser & Carleton (2005) placed H. eisentrauti and H. badius in synonymy because no clear morphometric distinction was shown between the two species by Van der Straeten & Hutterer (1986). However, the small size of the available sample prevented correct morphometric assessment of the variability for these species. For this study, 16 new Hybomys samples of Mt Oku were examined in order to test the evidence of skull variability among the CVL taxa.
