Dorsal profile gently curved from snout to dorsal-fin base; slightly slanted posteroventrally at dorsal-fin base, gently slanted to adipose-fin and moderately concave at caudal peduncle. Ventral body profile gently curved from lower jaw tip to pectoral-fin insertion, somewhat convex to almost straight to anal opening, slanted posterodorsally at anal fin base and slightly concave at caudal peduncle. Dorsal and ventral body contour rounded in cross section, somewhat compressed at base of dorsal and anal fins. Prepelvic region a little rounder than other body sections, postpelvic region slightly compressed. Caudal peduncle elongated, almost rectangular, slightly longer than high.

Ground color brownish grey, slightly darker at dorsum. Scale edges darker than centrum, forming an incipient reticulate pattern on body. One slightly elongated dark blotch on body side, occupying 2–4 scales horizontally and 1–2 vertically, situated over the LL scale series and placed at dorsal fin level. Fins yellowish to light grey, with interradial membranes darker (especially on anal and caudal fin). Pelvic yellowish with anterior edge grey. Adipose dark grey at base and free edge, with center yellowish (

Dorsum brownish grey, darker on head and anterior portion of body. Ventral portion of body light grey to yellowish. One black, slightly elongated blotch over lateral line scales, at dorsal-fin level. Scales with base and free edge darker than centrum, producing a conspicuous reticulated pattern especially in upper half of trunk. Pectoral fin yellow, dorsal and pelvic fins yellow to bright orange at distal portion. Caudal and anal fins bright orange to red, suffused with dark melanophores at base and along rays. Adipose fin yellowish grey with base and center darker (

. All the measured specimens were collected in the central portion of the Rio Amazonas basin near Manaus. Nevertheless, the species may be expected to occur along most of floodplain habitats of the Rio Solimões-Amazonas in the Brazilian states of Amazonas and Pará.

) resulted in only a few specimens of the new taxon, and usually just one collected each time, indicating a low abundance and apparently solitary habits of this species. However, this supposed rarity may be biased by the concentration of our collecting efforts around Manaus, which may represent a marginal distribution of this species.
