Distribution

This is a widespread and common species in savanna and grassland regions of southern Africa, including South Africa (Western Cape, Northern Cape, Eastern Cape, KwaZulu-Natal, Mpumalanga, Limpopo, Gauteng, North West, Free State), Angola, Botswana, Lesotho, Malawi, Mozambique, Namibia, Tanzania, Zaire, Zambia and Zimbabwe. It has been recorded from the following ecoregions: Angolan Mopane Woodlands, Drakensberg Montane Grasslands, Highveld Grasslands, Kalahari Xeric Savanna, Kalahari Acacia –Baikiaea Woodlands, Maputaland-Pondoland Bushland and Thickets, Nama Karoo, Namibian Savanna Woodlands, Southern Africa Bushveld, Southern Africa Mangroves, Southern Miombo Woodlands, Succulent Karoo, Zambezian and Mopane Woodlands, Zambezian Flooded Grasslands.

Remarks

This species has been collected in forest clearings, in weedy areas, in savanna on white clay soil, dry forest savanna, Thornveld savanna, Kimberley Thornveld, Miombo woodland, riverine-grassveld, old tobacco fields, sandy soil areas dominated by shrubs, and in citrus orchards. Tetramorium setuliferum normally nests in sandy to loamy soils, with nest entrances found in open areas. Circles of grass seed husks, piles of small stones or scattered soil particles have been found around nest entrances. Seeds are regularly found in nests. Reproductive forms have been collected from nests between October and February. Collected using pitfall traps, tuna baits, and sugar baits.
