Etymology: Hisonotus: Greek, isos = equal + Greek, noton = back (Ref. 45335); vespuccii: The specific name “vespuccii” comes from Italian and is in reference to Américo Vespúcio (Amerigo Vespucci in Italian), navigator and explorer to whom is attributed the discovery of the rio São Francisco in 1501 (Ref. 114934).
Eponymy: Amerigo Vespucci (1454–1512) was an Italian navigator after whom the Americas are named. [...] (Ref. 128868), visit book page.

Short description
Identification keys | Morphology | Morphometrics
Dorsal spines (total): 2; Dorsal soft rays (total): 7; Anal spines: 0; Anal soft rays: 6; Vertebrae: 27. Diagnosis: Hisonotus vespuccii differs from the congeners by having a unique coloration pattern of caudal fin with 1 black spot extending from its origin to the ventral lobe and 2 dark spots at the end of the lobe`s rays and the following combinationof character states (none is unique): odontodes forming longitudinally aligned rows (1 odontode after the other, but not necessarily forming parallel series) on head and trunk; a functional V-shaped spinelet; the presence of a single rostral plate at tip of the snout; the lack of contrasting dark geometric spots on the anterodorsal region of the body; a low caudal peduncle (depth 6–8% SL); few lateral median plates (21–23); and numerous premaxillary and dentary teeth (13–21 and 11–21, respectively) (Ref. 114934).
Facultative air-breathing in the genus (Ref. 126274); Associated with marginal vegetation in the rio São Francisco and in three of its tributaries, rio das Velhas, rio Paraopeba and rio Formoso; seems to be abundant through all rio São Francisco basin (Ref. 114934).
