Abstract

Simpsonichthys punctulatus, new species, collected in a seasonal swamp of the upper rio Paracatu drainage, rio São Francisco basin, central Brazil, is described. It is a member of the eastern clade of the subgenus Simpsonichthys, which also includes S. boitonei, S. santanae and S. zonatus, and is diagnosed by pectoral fin red with blue spots in males. Simpsonichthys punctulatus is distinguished from all other species of the subgenus Simpsonichthys by the presence of longitudinal rows of light blue dots on flank in males and a long fi lamentous ray on tip of dorsal fin in males.
