The lesser kudu (Ammelaphus imberbis, formerly Tragelaphus imberbis) is a forest antelope found in East Africa. It was first described by Edward Blyth in 1869. The lesser kudu at one time was thought to be a smaller version of the greater kudu, but now is considered to be a more primitive species. The lesser kudu are 90 to 110 cm (35 to 43 in) tall at the shoulder and weigh 60–100 kg (130–220 lb).
