Clés d'identification | Morphologie | Morphométrie
Rayons mous dorsaux (Total) : 10 - 12; Vertèbres: 33 - 34. Can be diagnosed by the following apomorphies: foramen in posterior region of metapterygoid forms an incomplete arch, bordered posteriorly by the hyomandibula; pectoral-fin rays bearing hooks; posterior margin of second infraorbital posteroventrally oblique and second infraorbital ventrally bordering anterior region of third infraorbital; fourth infraorbital more developed longitudinally than dorsoventrally; ascending process of premaxilla reaching just anterior end of nasal; and lateral line interrupted. Further distinguished from several characids by having 6-11 maxillary teeth and longitudinal, wavy stripes laterally on body in larger specimens (Ref. 89798).
Body shape (shape guide): short and / or deep.
Occurs in streams and semi-lentic and lotic shallow areas (up to 1.2 m deep) with moderate submerged vegetation and riparian vegetation composed by trees and shrubs. Streams are characterized by transparent water and bottom with mud, some stretches with sand or gravel (Ref. 89798).
