ေက်ာဘက္တြင္ရွိေသာ ေရယက္၌ပါေသာ အမွ်င္မ်ား (စုစုေပါင္း) : 10; ေက်ာရိုးမ်ား: 37 - 39. Knodus figueiredoi differs from all other species of the genus by having only tricuspid teeth in the inner premaxillary row (vs. teeth with 5 or 7 cusps). It can be further distinguished from all its congeners by having i,5,i (vs. i,6,i or i,7) pelvic-fin rays. It can be diagnosed from K. breviceps and K. savannensis in having a conspicuous, round humeral blotch (vs. inconspicuous, vertically elongate). It can be further distinguished from K breviceps in having five (vs. six) longitudinal scale rows between the dorsal-fin origin and lateral line, and from K. savannensis in having branched anal-fin rays 15-17 (vs. 20-21), and a hyaline caudal fin (vs. dark longitudinal band on lower caudal-fin lobe). It can be differentiated from Bryconamericus novae, the only species of the genus in the Araguaia-Tocantins basin, in having a conspicuous, round (vs. inconspicuous, vertically elongate) humeral blotch, 15-17 branched anal-fin rays (vs.18-20); five (vs. four) longitudinal scale rows between the dorsal-fin origin and lateral line; four large tricuspid teeth in the dentary (vs. pentacuspid); and presence of scale rows covering the basal portions of the caudal-fin lobe (vs. absence) (Ref. 97362).
Body shape (shape guide): fusiform / normal.
The type locality, Rio das Gasças, is a large and relatively deep river characterized by rapid waters and riffles, marginal sandbanks, and transparent water. The bottom of the river consists of stones, sand and moderate amount of the vegetal debris (Ref. 97362).
