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..

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5010 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00871 (0.00404 - 0.01876), b=3.07 (2.90 - 3.24), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).

Niveau trophique (Ref. 69278): 2.7 ±0.1 se; based on size and trophs of closest relatives

Résilience (Ref. 120179): Haut, temps minimum de doublement de population inférieur à 15 mois (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (13 of 100).
