With 149 currently recognized species, Hypostomus is one of the most species-rich catfish
genera in the world, widely distributed over most of the Neotropical region. To clarify the …

Distribution history of the widespread Neotropical genus Hypostomus was studied to shed
light on the processes that shaped species diversity. We inferred a calibrated phylogeny …

With an estimate of around 9,000 species, the Neotropical region hosts the greatest diversity
