Épines dorsales (Total) : 4 - 6; Rayons mous dorsaux (Total) : 7 - 9; Épines anales: 1; Rayons mous anaux: 16 - 20; Vertèbres: 47 - 49. Scales in lateral series above lateral band 47-53; and predorsal scales 24-26 (Ref. 47314). Differs from O. bicudo and O. ledae by the following characters: thin fragile premaxilla, not projected anteriorly in its medialmost portion; ventral head profile usually split into two straight sections, forming an angle at the retroarticular joint; snout short, as long as wide in dorsal view; mouth slightly upturned in lateral view and positioned above a horizontal line crossing near the center of eye and above a horizontal line crossing near the middle of head depth (Ref. 47314).
Body shape (shape guide): elongated.
Occurs exclusively in freshwater (Ref. 47314).
