Not. Could be an hybrid but also a totally original species. We can't be really sure DNA tests would be unreliable. This ray has being swimming in formaldehyde for more than a thousand years; The DNA is damaged beyond recognizable and many morphological aspects could had been seriously damaged also (Specially if improperly fixed). stingrays are specially sensitive to overfishing, but we need to remember that 90% of the ocean is still basically unknown, and the number of marine biologists expert in this family are... like four or so for the whole area?.
