Diagnosis

Description: A large stingray; disc rhombic, its anterior margins forming an obtuse angle (Ref. 81259). Dorsal surface partially rough, with scattered dermal denticles, more concentrated on head and trunk; an irregular mid-dorsal row of backward-pointing thorny tubercles with oval bases embedded in the skin, as well as two parallel scapular segments of small, irregular tubercles (Ref. 81259). Tail whip-like and spinous behind the sting, with a dorsal ridge and a well developed ventral fold as high as tail depth (Ref. 81259).

Colouration: Back greenish-grey-brown; belly white, pectoral margins slightly darkened; tail brownish behind the sting, ventral tail fold blackish (Ref. 81259).
