文摘

Megaleporinus is described to include ten valid extant species. Megaleporinus is supported by morphological, cytogenetical and molecular data. At least four undescribed, cryptic species, were identified. Synapomorphies include a ZW sex chromosome system. Paleogeographic and hydrogeological events have likely driven Megaleporinus speciation.
