This species has a wide distribution, ranging from northern Namibia and Angola, eastwards through south-eastern Democatic Republic of the Congo, Zambia, Zimbabwe and northern Botswana to western Tanzania, Malawi, eastern Mozambique and the northern and north-eastern parts of South Africa. The northern limits of the distribution range of this species are not well defined; although the range as shown here includes Rwanda and Burundi, where their presence requires confirmation.

There are two subspecies: G. m. moholi ranges from the eastern part of the species distribution to south-eastern Botswana, and is found throughout Zambia and intergrades with G. m. bradfieldi in the Western Province of Zambia; G. m. bradfieldi has been recorded from the Waterberg, Namibia, northwards into southern Angola, and eastwards to northern and northeastern Botswana and the Makgadikgadi Pan, and the Western Province of Zambia (Meester et al. 1986).
