Tragelaphus selousi is a regional form of sitatunga recorded in wetlands around Lake Ngami and the Zambezi basin. The described male was dark yellow-brown, with pale marks near the eyes and on the cheeks and throat.
The 1900 account is based on the skin and skull of an adult male from the Barotse River and gives his shoulder height as about 102 cm. He was dark yellow-brown overall, darker on the shoulders, belly, and legs, with pale patches extending inward from the eyes, a yellowish patch above the eye, pale cheek spots, and white patches on the throat. His horns measured about 65 cm along the curve. The adult female was hornless and nearly the same colour. The account also reports an immature female from Barotse as rich red with a dark back, while a Lake Ngami female, kept in captivity from half-grown, was nearly uniform in colour; the authors left this difference unexplained.
The 1900 book quotes Selous’s field account from the Chobe. In 1879 he watched one female standing chest-deep among reeds and feeding on young shoots just above the water; when disturbed, she splashed away through the water. Selous reported that the animals emerged from dense reed-beds only at night, but he saw only this one animal alive during that search.
