amazonum, Curimatus Humboldt [F. H. A. von] in Humboldt & Valenciennes 1821:165, Pl. 45 (fig. 2) [Voyage de Humboldt et Bonpland v. 2 (Title page 1833); ref. 5612] Rio Marañón, Cachoeira de Rentema, provincia de Saint-Jean de Bracamoros, Peru. No types known. The epithet amazonum [of the amazons, women warriors after which the Amazon River was named] is a noun in the genitive plural and should not be treated as amazonus or amazona.
