Phallobrycort synarmacanthus, a new species of Stevardiinae from the Xingu basin, Brazil (Teleostei: Characidae)

Phallobrycon synarmacanthus, new species, is described from the rio Bacajai (right bank tributary of the rio Xingu). It is recognized based on the presence of bilaterally arranged bony hooks on the last unbranched and anterior 11 or 12 branched anal-fin rays of sexually mature males, the presence of...
