 In 2001 , Lisa Rosenberger published a phylogenetic analysis of 14 Dasyatis species , based on morphology . The common stingray was reported to be the most basal member of the genus , other than the bluespotted stingray ( D. kuhlii ) and pelagic stingray ( D. violacea ) . However , D. violacea has generally been recognized as belonging to its own genus Pteroplatytrygon , and recently D. kuhlii has also been placed in a different genus , Neotrygon .
