The Tete veld aethomys or Tete veld rat (Aethomys ineptus) is a species of rodent in the family Muridae. It is found in South Africa and Swaziland. Its natural habitats are temperate forests, shrubland, and grassland. The common name refers to the type locality, Tete, on the Zambesi River.
The Tete veld rat is moderately sized, with a head-body length of 12 to 18 cm (4.7 to 7.1 in), an almost hairless tail measuring 14 to 17 cm (5.5 to 6.7 in), and a weight of 65 to 107 g (2.3 to 3.8 oz). The fur is reddish-brown over most of the body, but ticked with blackish hairs, giving an overall shade varying from brown to cinnamon. The underparts are white or very pale grey, with the fur being sharply demarcated from that on the rest of the body.
Tete veld rats are physically indistinguishable from the closely related red rock rats, and were thought to represent a subspecies of the latter until as recently as 1998. In that year, genetic analysis revealed that the two species were distinct, making the Tete veld rat an example of a cryptic species. Other than analysis of chromosomes or mitochondrial DNA, the two species can only be reliably distinguished by the shape of their spermatozoa, which have an unusual spatulated shape in Tete veld rats.
Because of the extreme physical similarity between Tete veld rats and red rock rats, the exact range of the latter is unclear, and some areas may exist where both species are found together. However, the current best estimate suggests that Tete veld rats are found in Swaziland and northeastern South Africa, where they are found in the North West, Limpopo, Mpumalanga, Gauteng, and KwaZulu-Natal provinces, and the northern part of Free State province. They may also be found in some neighbouring regions of Mozambique and Botswana, although this has yet to be confirmed. They prefer environments with substantial cover, whether from low-lying vegetation or rocky outcrops. While they are typically found at elevations of over 1,000 m (3,300 ft), they can also be found at much lower altitudes, including coastal forests near Durban.
