Neofundulus

''Neofundulus'' is a genus of fish in the family Rivulidae. These annual killifish are endemic to the Paraguay, Guaporé, Mamoré and São Francisco basins in Argentina, Bolivia, Brazil and Paraguay.Nielsen, D.T.B. & Brousseau, R. (2013): Description of a new species of annual fish of the genus ''Neofundulus'' (Cyprinodontiformes: Rivulidae) from the upper río Mamoré basin, Bolivia. ''aqua, International Journal of Ichthyology, 19 (3): 109-114.'' They inhabit temporary waters, such as swamps or ponds, that typically are located in open habitats like grassland. Once the water disappears, the adults die, but the eggs that have been laid in the bottom remain, only hatching after several months when the water returns.

They are small fish, with the largest species up to in total length.
