背棘 (總數) : 1; 背的軟條 (總數) : 79 - 89; 臀棘: 1; 臀鰭軟條: 79 - 89; 脊椎骨: 64 - 66. This species is distinguished by the following set of characters: body relatively deep, its depth at anal-fin origin 17-18% SL; greatest body depth 1.8-2.1 times length of longest first dorsal-fin ray; snout relatively long, horizontal length 4.8-5.6% SL; horizontal diameter of eye 5.3-5.5% SL, 1.1-1.2 times interorbital width; interorbital width relatively broad 4.3-4.8% SL; orbit-upper jaw relatively broad, width 2.7-3.4 % SL; caudal peduncle relatively narrow, its depth 1.3-1.6% SL; caudal-fin length 18-25 times caudal peduncle length; anal-fin base relatively long, length 54-57% SL; length of longest pelvic-fin ray 26-34% SL, 2.3-2.9 times length of longest first dorsal-fin ray; length of longest first dorsal-fin ray 11-12% SL; absence of accessory caudal-fin bones X and Y ; first ventral procurrent ray linked to hemal spine of vertebrae 7-8; dorsal-fin rays total 79-89; anal-fin rays total 79-89; pectoral-fin rays 21-23; caudal-fin rays 30-35; primary rakers in outer gill arch 17-19; total vertebrae 64-66; scales relatively large, ~18 in transverse line from anal-fin base posteriorly to dorsal margin of body (Ref. 122017).
