Abstract: Hypsolebias tocantinensis n. sp. is described from a temporary pool located in the rio Tocantins basin, Maranhão state Brazil. Hypsolebias tocantinensis belongs the H. flammeus species-group. It is the first occurrence of genus Hypsolebias in Maranhão state. This new species differs from all other species of that group, except Hypsolebias flammeus (Costa, 1989), Hypsolebias multiradiatus (Costa &Brasil, 1994) and Hypsolebias brunoi (Costa, 2003), by male color pattern and by the presence of a metallic blue sheen surrounding the black spots in the female. It differs from H. flammeus, H. multi-radiatus and H. brunoi by the shape of the dorsal and anal fins (rounded vs. pointed) and by the orientation of the reddish brown bars in males (diagonal vs. vertical). Hypsolebias tocantinensis differs from all other Hypsolebias by the presence of, in females, irregular light brown stains on the anal fins and by the pattern of the metallic blue sheen around the black spots (completely surrounding the black spots while in congeners this blue sheen is either absent or present in vertical bars).
