A new species of dung beetle, Proagoderus mabuensis Daniel, Josso, Nganhane & Strmpher, new species from Mount Mabu, northern Mozambique, is described, diagnosed, and illustrated. We provide a morphological comparison between the new species and a similar species from Mount Namuli, Mozambique, Proagoderus camiadei Josso, 2014. Both species belong to the Proagoderus dives (Harold, 1877) species-group. Furthermore, we provide an updated checklist of all known members of the dives species-group.
