Anoplolepis steingroeveri is a species of ant. It is commonly known as the black pugnacious ant. It is native to southern Africa, and occurs in South Africa, Lesotho, Botswana and Namibia.[1] The worker is similar in appearance to darker morphs of the common pugnacious ant (Anoplolepis custodiens), but that species has a chequer-board-like dark pattern on the gaster, which is caused by reflection of light by pubescent hairs which lie in different directions on the two sides.[2]
