All the representatives of said "species", IME, have all had far more extensive striping/networked patterns than is regularly encountered in L-260, and I should know--I have kept trios of both.
Here are some, not in any particular order, "monte dourado" specimens (with due respect to their photographers);
They look quite similar, IMO, to the fish in question, not to mention that differing individuals have varying wash hues; even those by-caught together; take a look at the PC profile or something.
This, also, is in light of recent influx of Rio Jari specimens gaining more widespread popularity and henceforth importing interest. Given so many signs pointing to said "species", I do not personally believe that it is likely to be anything else.
