Etymology: Megaleporinus: Name from Greek 'mega' meaning large or largest, plus Leporinus, the genus which most species (now in this genus) were previously assigned; refrring to the large size of most congeners; brinco: The specific name brinco refers to the vernacular name of the species, 'piau-brinco', which means a species of Leporinus ('piau') with an earring ('brinco' in Portuguese) in allusion to the red blotch behind the head, immediately dorsal to pectoral-fin origin. A noun in apposition.
