Épines dorsales (Total): 1; Rayons mous dorsaux (Total): 7; Rayons mous anaux: 12 - 14; Vertèbres: 44 - 46. Can be differentiated from its congeners by a unique combination of the following characters: head length 31.0-34.3% SL; dorsal to adipose distance 7.3-10.9% SL; length of dorsal-fin 27.3-30.8% SL; post-adipose distance 14.7-16.2% SL; interorbital distance 28.1-31.1% HL; presence of filamentous extensions on the first three dorsal-fin rays in adults (Ref. 38441). Depressed dorsal fin reaching adipose fin; adipose fin same color as body; body and fins a uniform dark brown; crenulate ridge along anterior edge of pectoral spine; 8 branched anal-fin rays (Ref. 12693). Elongated upper caudal lobe ending in a filament (Ref. 43281).
