Short description Identification keys | Morphology | Morphometrics
This species possess a longer body, smaller interorbital space (equal to that of the mouth width which is 0.78-0.82 times the pre-oral length); short caudal fin; differently-proportioned first dorsal fin (interdorsal space, 24.6% to 25.8% of TL); relatively short snout; prenarial length 0.64-0.69 times mouth width and 1.32-1.59 times eye length; denticles wide, tricuspidate, overlapping, and rhomboid; caudal 'bar' present at the fork of the caudal fin; dorsal caudal lobe wide, and a broad rounded tip (Ref. 120195).
Body shape (shape guide): fusiform / normal; Cross section: angular.
