Pastinachus is a genus of stingrays in the family Dasyatidae. This genus was long held to be monotypic, containing only the cowtail stingray (P. sephen). Recent studies of Indo-Pacific stingrays have revealed that there are in fact a number of different species of Pastinachus, and that some former junior synonyms may need to be resurrected. [1]
Combining the molecular genetic relationship analysis of the NADH2 DNA, which was used to assign Pastinachus stellurostris, [2] and the analysis of the COI gene, which was used to evaluate P. gracilicaudus accordingly, [3] results in approximately the following cladogram for the genus:
