Common names: Fat Mouse (English), Vetmuis (Afrikaans), Thilivhe (Tshivenda), Thanyani (Xitsonga), Igundane (Zulu). Distribution: Although the extent of its distribution remains under scrutiny, the range of the Fat Mouse is currently considered to stretch widely across the savannahs of southern Africa, and marginally into East Africa. The records from Kenya and Ethiopia may, however, represent misidentified specimens of S. parvus (Happold 2013; Monadjem et al. 2015). In southern Africa, this species has been recorded across northern Namibia and Botswana, throughout Zimbabwe, into parts of Mozambique, extensively into northeastern South Africa, and across Swaziland but not Lesotho (Lynch 1994). In South Africa, it has a relatively wide distribution across the Limpopo, Gauteng, North West, Mpumalanga and KwaZulu-Natal provinces (Figure 1; Skinner & Chimimba 2005). In the North West Province, this species is restricted to the northeastern bushveld regions (Power 2011), and its distribution probably does not extend further west than Pilanesberg National Park (Rautenbach 1982; Power 2014), although Monadjem et al. (2015) show a record more westerly on the border with Botswana.
