摘要：

Aequidens pallidus (Heckel) reaches c. 140 mm standard length and occurs in the drainages of the blackwater rivers Negro, Puraquequara, Preto da Eva and Uatuma in Brasil. Aequidens duopunctata Haseman is a junior synonym. Aequidens tubicen sp.n., was collected in the Trombetas and Mapuera rivers a little upstream of Cachoeira Porteira. The largest specimens is 116 mm standard length. It differs from all other Aequidens species in the possession of a dark spot at the inner angle of the preopercle and adjacent cheek. Aequidens pallidus and A. tubicen form a group diagnosed by a high number of vertebrae (14 + 13 = 27) and three colour pattern synapomorphies: lateral band positioned more dorsally and the midlateral spot positioned more posteriorly than in other Aequidens species, and caudal spot preceded by a large light spot at the dorsal margin of the caudal peduncle.
