Short Description
Original diagnosis after LAST, WHITE & NAYLOR, 2016 [24346]: A species of Himantura distinguished by a combination of the following features: disc weakly rhomboidal; preorbital snout moderately short (length 19–22% DW), rather broad, angle 117–127°, with a distinct apical lobe; lateral apices narrowly rounded; orbits moderately large, often strongly protruding (particularly in young); 1–2, mostly heart-shaped suprascapular denticles (not preceded before and after by a row of smaller primary denticles); secondary denticle band developed before birth; dorsal surface of juveniles (smaller than 370 mm DW) dark spotted or with spots and weak reticulations, subadults and adults (exceeding 390 mm DW) more strongly reticulated; dorsal tail of juveniles with 3 rows of spots before caudal sting, faint dark saddles beyond sting (tail lacking alternating black and white bands); tail uniformly dark ventrally; pectoral-fin radials 146–152; vertebral centra (excluding synarcual) 123; including synarcual 124.

Dentition
Teeth in a juvenile paratype (CSIRO H 4542-06) small, subequal in size in upper and lower jaws; narrowly rhombic with 1–2 low, transverse ridges on crown, ridges separated by prominent groove; ~59 vertical rows in upper jaw [24346]
