Dorsale stekels (totaal) : 9; Dorsale zachte stralen (totaal) : 10 - 11; Anale stekels: 3; Anale zachte stralen: 7. Silvery in color but olive brown above; brown stripes following scale rows above lateral line and the 4 rows below it; spinous dorsal fin with black margins (Ref. 4372). Squamation pattern on the preopercular flange 5-17 scales (Ref. 41102).
