Épines dorsales (Total) : 2; Rayons mous dorsaux (Total) : 7; Rayons mous anaux: 37 - 40.
Body shape (shape guide): elongated.
Occurs in medium to large-sized rivers (Ref. 12975). The stomachs of the specimens examined were more or less filled with mollusks, usually bivalves (Ref. 7432). Enters flooded forest (Ref. 9497).
