Many sources suggest that L113 is also L234. Both are spotted. L113 is from the Rio Paraná and has a darker base colouration and, at least in adulthood, a lower dorsal fin. L234 is closely related but from the Rio São Francisco and has a lighter base colouration and, at least in adulthood, a taller dorsal fin. This confusion stems from the original L234 (DATZ, 1996) article which shows the Rio São Francisco fish but incorrectly states it came from the Rio Paraná. Possibly collection data was mixed up or commercially sensitive and so was not reported accurately.
