Most of the retics are actually orbignyi
No.
The hobby has always used reticulatus about the ray we see in your papers as magdalenae. You can take a look around this forum if you want to see for yourself.
The same thing can be said about fx. the fish we know in the hobby as scobina. Its actually from Rio Tocantins (holotype collected near Cametá) while the fish we see on the forums listed as scobina, is caught in the xingu (IBAMA has released pics of the real scobina).
And the list goes on...
Best thing is to just ignore it.
