Geographic Range [top]

Range Description: This species has been recorded from both West Africa and East Africa, and presumably ranges more widely between the known records. In West Africa, it has been recorded from Mauritania, The Gambia (at Sapu), Senegal, Mali, Sierra Leone (Mount Loma) (Grubb et al. 1998; Hutterer 2005). It has also possibly been recorded from Guinea, Côte d'Ivoire, Ghana (Pinkwae) and Nigeria, but the identity of these animals is unclear and they are not mapped here. In East Africa, it has been recorded from Uganda (the type locality is probably Entebbe), Kenya and Tanzania (including Ngorogoro) (Hutterer 2005).
