Abstract

Simpsonichthys carlettoi, an annual fish collected in the upper Rio das Rãs floodplains, middle Rio São Francisco basin, north-eastern Brazil, is described. It seems to be closely related to S. magnificus and S. picturatus, with unpaired and pectoral fins in males in all three species possessing the same derived colour patterns. The new species differs from S. magnificus and S. picturatus in having dorsal and anal fins pointed in males, and by the absence of a black distal edge on the unpaired fins of males.
