A new Hyphessobrycon (Characiformes: Characidae) from the rio Xingu Basin, Brazil
ABSTRACT A new species of Hyphessobrycon is described from the middle and lower rio Xingu Basin, Pará state, Brazil. The new species can be distinguished from all congeners by the combination of a large caudal peduncle blotch (largest in mature males), absence of humeral blotch, and largest teeth on dentary, inner premaxillary and maxillary relatively compressed with 6-9 cusps. The new species is compared to three other congeners with similar color pattern: Hyphessobrycon diastatos Dagosta, Marinho & Camelier 2014, Hy. negodagua Lima & Gerhard 2001, and Hy. parvellus Ellis 1911, and one species of Hemigrammus, He. rodwayi Durbin 1909.
