Bathytoshia is a genus of stingrays in the family Dasyatidae found worldwide in tropical and warm temperate oceans (except the East Pacific and tropical Indian Ocean). It was formerly regarded as a junior synonym of the genus Dasyatis.[1]
Species

Molecular phylogenetic data indicate that several previously recognized Dasyatis species are in fact populations of wider-ranging Bathytoshia species.

Bathytoshia brevicaudata (F. W. Hutton, 1875) (including Dasyatis matsubarai)
Bathytoshia centroura (Mitchill, 1815)
Bathytoshia lata (Garman, 1880) (including D. thetidis, D. ushiei, and eastern Atlantic B. centroura)
