Potamotrygon tigrina , that must be the coolest name so far

Good to hear ichthyologists are describing freshwater stingrays better and better.

There is a lot of controversy within the field of scientists who work with rays, with these guys re-naming various species , as they don't do any actual field work and rely on hobby trade exporters for their samples, and we all know how flawed that can be.
Recently they redescribed and renamed Menchacai ( Tigers) and said they are the same species as Flowers. Now they are re-naming what to me ( from the picture) is clearly a Tiger ray ( ie: Menchacai)
They have done this with a few species in the last year or so. No problem with the redescibing, but the re-naming also just 'muddies the water'.
Aqualog already had a 'Tigrinus' ( castexi variant) ray , a Tigrillo ray ( another castexi variant) and a Tiger ( menchacai) ray described.
imo all they are doing s increasing the confusion
