Tiger Rays come from Peru.
True Hystrix do not come Peru.
True Reticulatas do not come from Peru.
Is this an asian exporter/breeder? Importer? Wholesaler?
All these stingrays do not come from the same area, or even close.. What is he asking for True Hystrix? Anything less than $200 and they are not 'true'.. Ask him when these 'true hystrix' were imported, and if it was anything less than 2 years ago, than they are not 'true'..
Laticeps and Signatus are likely 'made-up' or 'out-dated' names that exporters give to their unidentified rays.. They were probably scientifically reclassified many years ago, atleast laticeps was.. Signatus is probably a brown peruvian motoro variant that they needed to find a name for..
for whatever reason they found a name that they think works, but likely its from an old book, old fishermans nickname, or just because the exporter felt like naming it.
If the exporter you are purchasing these 'true hystrix' from is really irresponsible to the point of claiming they are 'true hystrix', I wouldn't recommend purchasing from them at all.
Do you work with Massive Aggression at all? He works with PAEX, who labels his rays a bit more appropriate..
