A short-snouted species of Dasyatis with a broad rhomboidal disk. Eyes and spiracle large. Tips of pectoral fins subangular (not rounded).

Median denticles continue down the tail to the caudal spine. Additional denticles on the head are often present. Ventral fin-flap much larger than dorsal. Tail long and whip-like with spine close to tail base. Pelvic fins protrude beyond pectorals.


Disk gray-green to gray-brown with a thin white margin. Dorsum covered in numerous black speckles. Caudal finfolds black. Ventrum white.

Petean, F.F., Naylor, G.J., & S.M. Lima. 2020. Integrative taxonomy identifies a new stingray species of the genus Hypanus Rafinesque, 1818 (Dasyatidae, Myliobatiformes), from the Tropical Southwestern Atlantic. Journal of Fish Biology, 97(4), 1120-1142.

Other Notes

This species is sister to the eastern Atlantic Hypanus rudis, which in turn are sister to the eastern Pacific H. longa and the NW Atlantic H. americanus. The pattern of black speckles on the dorsum best distinguishes it from H. americanus (Petean et al., 2020).
