Hyphessobrycon heliacus n. sp. is described from the upper rio Tapajós basin, Mato Grosso, Brazil. The new species is distinguished from other currently recognized Hyphessobrycon species by the combination of an enlarged caudal spot, the golden body coloration in life, the elongate filamentous dorsal and pelvic fins, thickened anal fin rays, and the absence of anal fin lobe. These last three characteristics are present only in mature males.
