The extant species of fleas in the North American ceratophylline genus Malaraeus Jordan, 1933, are reviewed and redescribed. Malaraeus sinomus (Jordan, 1925) is considered to be a junior synonym of Malaraeus eremicus (Baker, 1904). The second species, Malaraeus telchinus (Rothschild, 1905), is the commonest member of the genus. Traubella grundmanni Egoscue, 1989, is treated as a third species of Malaraeus. A key to the species is provided and the diagnostic characters of the three taxa are illustrated.
