背棘 (總數) : 2. Diagnosis: caudal peduncle relatively long, with minimal depth as large as horizontal distance between adipose and caudal fin bases, or in a few cases almost twice as large as the horizontal distance between the adipose and caudal fin base (never twice as large); pectoral spine almost completely smooth on its anterior margin; preorbital head length less than maximum head depth; colouration pattern on flanks faint and not clearly demarcated, often with 1 horizontal row of round spots on flanks; adipose fin mostly very well-developed (height 5-8% SL), dorsal fin high (19-30% SL), head deep (head depth 79-97% head width)(Ref. 81642).
