spend their entire lives in shallow seasonal pools formed by rains, in different natural areas of South America (Costa, 1995), including rainforests (the Amazonian forest and the Atlantic forest, including the adjacent coastal Restinga); semiarid areas (the Caatinga of northeastern Brazil, the Gran Chaco of Paraguay and Bolivia, and a coastal area of Rio de Janeiro state, southeastern Brazil); and savanna-like regions such as the Brazilian Cerrado, which includes forested vegetation formations such as the Mata Ciliar and Mata de Galeria, and open vegetation formations as Campo Limpo, Brejos, and Buritizal (Buriti-palm). The pools in all these regions are dry during some months of the year (usually between July and November), when all individuals

is the strong sexual dimorphism, the males possessing striking color patterns and longer fins than females. Meristic differences between sexes of the same species are common, especially with regard to numbers of dorsal and anal rays (counts in males are always greater). In addition, the dorsal and anal fins of males often have filamentous rays. Because of their small size, beauty, and diversity of color patterns and fin morphology, species are widespread in the aquarium trade, often appearing in aquarium magazines and on internet sites throughout the world. Several species are maintained by specialized breeders and have become popular aquarium fishes.

were described after 1941, and 46 of these have only been described within the last 20 years. This is a consequence of recently increased interest in South American seasonal fishes, which has resulted in greater collecting effort and an increased number of publications involving the ecology and taxonomy of these fishes. This work has also revealed, unfortunately, that several species are threatened with extinction (Costa, 2002).

have been the focus of recent phylogenetic studies (Costa, 1996, 1998, 2003, 2006a). Despite this work, some species are still poorly known, and data on morphology and geographic distribution is often limited to that appearing in their original descriptions. The present revision incorporates a considerable amount of new information; including detailed descriptions of species, primary synonyms, taxonomic keys to subgenera and species, lists of material examined, and information on geographic distribution and habitat for each species.
