Diagnosis. Tetragonopteurs argenteusis distinguished from all other congeners by having 11–17 predorsal scales ( vs.7–9). It further differs from T. anostomus, T. denticulatus, T. kuluene, and T. juruenaby having 4 principal teeth in dentary ( vs.5–6), and larger and more robust teeth ( vs.thinner and sharper teeth; Silva et al.2013: Fig. 2). Tetragonopterus argenteusdiffers from T. anostomusand T. araguaiensisby having 12–15 gill-rakers on the upper limb of the first gill arch ( vs.17–20; Silva et al.2013: Fig. 3); it also differs from T. anostomusby having a terminal mouth ( vs.subsuperior mouth). Tetragonopterus argenteusdiffers from T. ommatus sp. n.by bearing 1–4 maxillary teeth ( vs.7–8) and by the presence of a conspicuous dark mark on the caudal peduncle ( vs.inconspicuous mark limited to the posterior portion of the caudal peduncle). Tetragonopterus argenteusdiffers from T. carvalhoiby the presence of a rounded dark mark on the caudal peduncle ( vs.lozenge-shaped dark mark on the caudal peduncle). Tetragonopterus argenteusdiffers from T. rarusby the absence of dark longitudinal stripes on the trunk ( vs.presence of such stripes); it differs from T. rarusand T. georgiae n. comb.by having 3.5 scale rows between lateral line and pelvic-fin origin ( vs.4.5–5.5). Finally, T. argenteusdiffers from T. denticulatusby having humeral marks separated by one or two vertical rows of scales ( vs.humeral marks separated by three vertical scale rows).
Description.Morphometric data presented in Table 2. Body deep, compressed laterally, with greatest depth at dorsal-fin origin. Dorsal profile slightly convex between snout tip and vertical through middle of orbit; slightly concave from this point to end of occipital process; convex from that point to dorsal-fin origin. Slightly convex from dorsal-fin origin to adipose-fin end. Prepelvic region transversely flattened with distinct, longitudinally aligned lateral keels. Ventral profile of body convex from lower lip to anal-fin origin; straight or somewhat convex along base of anal fin. Caudal peduncle with dorsal and ventral profiles slightly concaves.

Premaxilla in two rows of relatively robust teeth. Outer row with 4 (6), 5 (68), 6 (104), 7 (31) or 8 (10) teeth with three cusps, central cusps longest. Inner row with 4 (1), 5 (228) or 6 (3) teeth with three, four or five cusps; if present, central cusp twice as long and broader than other cusps. Maxilla with 1 (3), 2 (62), 3 (132) or 4 (29) teeth with three cusps. Dentary with 3 (1) or 4 (228) anteriormost teeth with three or five cusps followed by a smaller tricuspid tooth and 8–13 smaller conical teeth of similar size (5 c&s).
