Morphology | Morphometrics
soft rays: 8. This species can be diagnosed from all congeners by the combination of the following characters: lateral line incomplete, with 3-4 pored scales; 20-21+1 scales in the lateral series, ½4/1/2 scales in transverse line on body; 8 predorsal scales; last unbranched dorsal-fin ray strong, curved, serrated, with 24-27 large, curved serrae on posterior margin; barbels absent; a broad black band around caudal peduncle covering scales 17-19 of longitudinal series. Three diffuse black blotches on body, first behind opercle, second below dorsal-fin origin, third above anal-fin origin. Black spots at base and root of dorsal, anal and pelvic fins (Ref. 94011).

= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01096 (0.00516 - 0.02330), b=2.99 (2.82 - 3.16), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 2.8 ±0.2 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low vulnerability (10 of 100) .
