Fornasinius hermes sp. nov. is described from North-East Uganda; type locality: Mt Morungole, Kidepo valley. The new species is reminiscent of Fornasinius fornasini Bertoloni, 1852 and Fornasinius aureosparsus (Neervoort Van De Poll, 1890), but presents a combination of constant characters that distinguish it from both taxa: protibia strongly tridentate, mesotibia with external tooth and cephalic apophysis with proximal lateral teeth.
