| Diagnosis |
Can be differentiated from its congeners by the unique combination of the following characters: head width 18.3-19.5%SL, length of caudal peduncle 18.8-20.7%SL, depth of caudal peduncle 9.4-10.3% SL, length of adipose-fin base 21.2-26.3%SL, dorsal to adipose distance 6.3-8.6%SL, absence of a dark midaxial streak, 4-7 serrations on dorsal spine, bifurcated serrae on the pectoral spine, upper lobe of the caudal fin rounded posteriorly, dorsal fin without an extended second ray, with broader membranes and allowing the fin to be spread wider to give a more rounded appearance. |
