Abstract

A new species ofHyphessobryconis described for the upper Munim and Preguiças river basins, northeastern Brazil, supported by morphological and molecular species delimitation methods. This new species belongs to theHyphessobryconsensu strictogroup, as it has the three main diagnostic character states of this assemblage: presence of a dark brown or black blotch on the dorsal fin, absence of a black midlateral stripe on its flank and the position of Weberian apparatus upward horizontal through dorsal margin of operculum. Our phylogenetic analysis also supported the allocation of the new species in this group; however, it was not possible to recover the species sister-group.PristellamaxillarisandMoenkhausiahemigrammoideswere recovered as the sister-clade of theHyphessobryconsensu strictogroup.
