Dorsale stekels (totaal): 2; Dorsale zachte stralen (totaal): 5-6; Wervels: 31 - 32. Diagnosis: Labial disk moderately developed and rounded, covered with large papillae; mandibular barbels little developed, auxiliary barbels absent; premaxillary teeth large and arranged in 3-4 rows; mandibular teeth numbering 4+4 to 5+5, sometimes even 6+6; dorsal fin with 5-6 branched rays, the 6th soft ray always slender, very close to 5th; adipose fin short, beginning slightly ahead of anal-fin origin; caudal peduncle rather elongate, but less so than in C. batesii; caudal fin deeply forked, with distinctly pointed lobes, lower lobe longer than upper; usually a longitudinal black band on one or both lobes of caudal fin; eyes moderately developed; sexual dimorphism absent or weak (Ref. 57223). Colouration: body with 3 more or less well defined dark vertical bars separated by paler areas; lower caudal-fin lobe, and sometimes also the upper, with a more or less distinct black band (Ref. 57223).

Estimates based on models

Fylogenetische diversiteitsindex (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).
Trofisch niveau (Ref. 69278):  3.2   ±0.4 se; based on size and trophs of closest relatives
Weerstandsvermogen (Ref. 120179):  Hoog, minimale populatieverdubbelingstijd minder dan 15 maanden (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
