This species is distinguished by having the anterior disc margin distinctly undulating; pectoral-fin apices narrowly or abruptly rounded; preorbital length times orbital length 2.00-2.68; preorbital length times interorbital length 1.02-1.30; interorbital space times orbit length 1.20–-1.50; orbital length times spiracle length 2.00-2.53; with a median row of thorns originating from the posterior half of the disc; number of median thorns 26-30; interdorsal thorns 1 or 2; the dorsal disc surface and tail with finely textured denticles on adults confined to a narrow median band originating just posterior to mid-disc and extending along the tail; teeth arranged in quincunx; predorsal tail vertebrae 62; total predorsal vertebrae 93; pectoral-fin radial count 72. Colouration: uniformly colored on their dorsal and ventral surfaces, no blotches, spots, or other distinctive patterns which is consistent at all sizes from young to adult (Ref. 127873).
