Macopaeus is a spider genus of the Salticidae family (jumping spiders). Its only described species, Macopaeus spinosus, is endemic to Madagascar. Two other species (M. celebensis Merian, 1911 and M. madagascarensis Peckham & Peckham, 1903) were described in this genus in the early 20th century. However, these were transferred to the genus Brettus in 1980.
